Annapurna III

Annapurna III is a peak from Annapurna massif which measures over 7,000 meters. It was first climbed in 1961 by the Indian expedition through the Northeast face. It’s Southeast face has never been climbed.


Annapurna III is the 42nd highest mountain that is not the subsidiary of another peak. It measures 7,555 meters (24,787 ft). The prominence of the summit is 703 meters. Along with Annapurna I, II,IV and V, it forms the greater Annapurna massif.

Annapurna I remains the popular peak for climb among the all.


The Northeast face of the peak was first summited by an Indian expedition led by Cap. Mohan Singh Kohli in 1961. It comprised of Cap. Mohan Singh, Sonam Gyatso and Sonam Girmi.

The Southeast fae has never been climbed before. The summit was attempted by a team, however, the entire team perished before they could make it to the top.

The latter summit was attempted by David Lama and the team in 2016 and 2017. However, they failed to successfully scale the peak.

Leah Thomas & Her Mera Peak Feat!

Leah Thomas (26) hails from Vermont, USA. An outdoor enthusiast, she guides rock climbing trips at Cat Ba, Vietnam through Asia Outdoors.

She recently completed her 17 days trip to Mera Peak summit. An arduous climb, Mera Peak makes up for the highest climbable small peaks in Nepal. At 6,476 meters, Mera Peak makes an exciting trip which includes both trekking and minimal climbing experience.

She says,

From the start, Caravan Outdoors was really easy to work with. I talked mostly to Salman who helped me through each step of the process of getting signed and getting to Nepal. I had never done anything like this before, climbing a peak, and they were very helpful in directing me to what I needed to get and do before arriving.

I ended up being the only one on my trip, but it was great. I summited Mera Peak (6400+ meters) which I had my doubts on doing since I was coming directly from sea level, but was able to do it with no major problems!

It was a great experience, the guides were amazing, the trip was amazing! I can’t say enough good things, I’m already looking to go back and do anther trip!

Insight on Everest Trekking

Mount Everest is the highest peak on earth. It attracts more than 50,000 people in a year to trek through the treacherous trail to reach its base camp. But, there’s more to the trekking than just seeing the Everest. The Sherpa inhabitants of the region, their native culture, rich biodiversity and the sight of humongous mountains are few treats of the trekking.

Everest Region

With the commercialization of Mount Everest, the trekking began in late 80s. Since then, millions of tourists have visited the Khumbu (Everest) region; few of them comprising of climbers. Today, the Everest Base Camp along attracts more than 50,000 tourists in a year.

Over 5,000 people have summited the Everest. With availability of better logistics and assistance, more climbers tend to join the expedition every year bringing the total summits over 300 per year.

Mount Everest

Khumbu is mostly accessible through a short flight from Kathmandu to Lukla. Those who wish to map it on foot can arrive through Jiri village. It may well take over 9-10 days to trekking to reach the base camp. However, there aren’t any lodges available in the base camp, hence, you must stay at Gorakshep or Lobuche before approaching it.

Kala Patthar at 5,643 meters is located just above the base  camp. It’s a small hill or the monument where the trekkers can spend time enjoying the up-close glimpse of the Mount Everest. (Note: Everest isn’t visible from the base camp. The towering Lhotse peak blocks the entire view)

Namche Bazaar, Gokyo lakes and Tengboche are another major attractions in the region. Namche and Tengboche are accessible through the usual trail, however, you must take an entirely different route to reach the Gokyo lakes. Gokyo is a discreet village located at the western section of Khumbu.


The trek is generally strenuous and may require walking over 5 hours a day. It begins at Lukla. The trail aslowly ascends towards Namche Bazaar through Phakding. Namche is the most populated Sherpa town and is known for its luxury lodges, markets and ethnic lifestyle. Hiking around the place or staying a day more is recommended.

The trek ascends further towards Tengboche. Tengboche boasts the highest monastery on Earth. The monastery is over 100 years old and the popular Mani Rimdu festival is held every year to commemorate its legacy. Few other Sherpa villages, you’ll come across are Dingboche, Lobuche and Gorakshep before heading towards the Everest Base Camp.

You can hike to the base camp from Lobuche in few hours and come back to Gorakshep to stay overnight. The next day, you an make an early hike to Kala Patthar and start descending the usual way afterwards.

Anyone from the age 8 to 59 can do this trek, with sound health and proper assistance. Acclimatization is essential to get used to the local environment and altitude.


  • The Everest was attempted by British mountaineer George Mallory before it was successfully summited by the 9th British expedition
  • Sir Edmund Hillary and Tenzing Norgay Sherpa became the first humans to touch the summit of the peak, in 1953.
  • Over 5,000 people have summited the Everest since 1953.
  • Reinhold Messner became the first person to summit the Everest without the use of bottled oxygen
  • The term Sherpa actually signifies the native tribe of Khumbu region. Today, Sherpa is used as a misnomer for porters, guides and such.
  • Over 250 people attempt the summit in a single day every year during the climbing season of May.
  • The disaster of 1996’s at Everest cost 15 lives. The incident was later adapted into the best-seller, Into Thin Air.
  • The popular trekking seasons are Spring and Autumn. They last from March to June and September to November simultaneously.

Island Vs Mera Peak

Nepal is an abode of Himalayas. It’s gifted with some of the most majestic mountains in the world. Out of the 14 Eight-Thousander peaks, 7 remains in Nepal. Along with these mighty mountains, there are 100s of smaller peaks which caters the enthusiastic climbers. These can be cheaper than climbing the Everest and can be completed with ease.

Island Peak and Mera Peak are the two most popular smaller peaks in Nepal. These two mountains attract the most amount of climbers in the country. The climb may account for a day or two, hence, it easier to undertake small peak climbing. An expert as well as an amateur climber  can complete the climb without the need of any expedition.

Here are some holistic differences between the two to help you decide better.

Island Peak

Island Peak or Imja Tse is a small peak located at the Khumbu region. It measures 6,189 meters (20,305 ft). It was named Island Peak by Eric Shipton’s party in 1951, since it appears as an island in a sea of ice when viewed from Dingboche.

An Alpine PD peak, you need to have proper technical skills to ascent the peak. Cramponing, harnessing and ice-axing is essential. A Sherpa guide will always be there to assist you during the climb. Most of  the trail encounters trekking, however, the last 400-500 m section requires climbing through snow and rocks.

The ascent is generally started during early morning. Around 2 am, you get up and ready to tackle the climb with your ice-axe, ropes and head-lamp. You may reach the summit around 11 am-12 pm in the morning. The rest of the time will be spent descending all the way to the Chhukung village, which offers better tea-house for lodging.

Mera Peak

Mera Peak at 6,476 meters (21,247 ft) is known as the highest trekking peak in the world. An Alpine PD peak, it is technically superior than most smaller peaks in the region. it is located in the Hinku valley of northeastern Nepal. It contains 3 main summits. Most climbers take on Mera North, the highest of them all.

You would need proper technical skills to ascent the peak. Cramponing, harnessing and ice-axing will be equally essential. A proper  logistical support and qualified Sherpa guides will always be there to assist you. From the summit, 5 of the major peaks will easily be visible, including Mount Everest.

Most of the trail accounts for trekking. The final 600-700 meters ascent requires climbing through snow, rocks and ice. The ascent starts early morning. You may reach the summit by noon and back to Lower Base Camp by the evening.

Ascent Profile & Logistics

Mera and Island Peak
Mera and Island Peak

Both the trip starts and ends at Lukla. The commute to Lukla is facilitated by the domestic flights. You’d generally trek 10-12 days and keep 2 days for climbing. A spare summit day is kept in case you aren’t able to summit the previous day due to bad weather.

Island Peak’s summit is just 287 meters lesser in height than the Mera Peak’s summit. Both requires a good amount of ice-axing, alpine style of climbing through ropes and cramponing. As the summit generally lasts only a day, the lengthy climb may prove to be a fatiguing experience for the most climbers.

10 Died Climbing the Everest in 2017

The Mount Everest has already usurped 10 innocent lives in 2017. The Spring season is popular for climbing the Everest, as the small window opens only for short time during May. Almost 509 climbing permits were issued for the Spring season.

373 permits were issued for summits from the Southern side (Nepal), while 136 were issued for summits from the Chinese side.

Brief History

Mount Everest stands at 8,848 meters, making it the highest peak in the world. It’s in the Mahalangur himalaya range and falls in Nepal and China on Southern and Northern side, respectively. The first successful ascent of Mount Everest was made on 1953 by the 9th British Expedition team, including; Edmund Hillary, John Hunt and Tenzing Norgay Sherpa.

Ever  since the commercialization of climbing in Nepal, more than 5,000 climbers have scaled the Everest. Most of the climbs took place only after 2000. The availability of logistics and assistants lately has made the expedition easier.

Reinhold Messner became the first person to climb Everest without the use of supplemental oxygen. Since then, many climbers have made a point to climb the Everest without the use of supplemental oxygen.

Dead Indian Climber’s body to be retrieved

Nepal Mountaineering Association (NMA) is on a task to retrieve the body of an Indian climber Ravi Kumar who died while descending from the summit on May 28. He purportedly fell 200 meters from the route and into the crevasse.

The move to retrieve the body has come under scrutiny and criticism by the chairperson of NMA Ang Tshering Sherpa, as they are supposedly forced by the Indian embassy and the family of the deceased to retrieve the body.

It would have been a different thing if was alive. We should be mindful and not be taking the decision to get the body from such a danger zone. The family should understand that. It’s too dangerous to recover a body from such a difficult place ~Ang Tshering

Spanish climber makes a record

Kilian Jornet
Kilian Jornet

The 29 years old Spanish climber Kilian Jornet has summited the Everest without supplemental Oxygen twice in the same week.

He summited the mountain from the south and north sides. The first climb was completed in 26 hours, and the following climb was completed within 17 hours.

Today I felt good, although it was really windy so it was hard to move fast. I think summiting Everest twice in one week without oxygen opens up a new realm of possibilities in alpinism and I’m really happy to have done it. ~Kilian

5 Best Climb Movies

There can’t be other pleasures than watching the movies – masterpieces – ever made on the subject, Climbing. Since the advent of commercial climbing and digital tech, many unexpected climbs have been captured or filmed for the fun of watching.

Well, here are 5 of such movies which have made a mark with their amazing story and cinematography. You must add these movies in your bucket-list.

#1 Touching the Void (2003)

touching the voidTouching the Void recalls the story of 2 climbers who faced an ill fate during the climb of the Six-thousander Siula Grande in Peruvian Andes in 1985.

Joe Simpson and Simon Yates venture out to ascent the Siula Grande. Their ascent goes well, however, while descending they a face sudden storm which encapsulates the entire summit. The succeeding plots cover more on Joe’s ordeal. He survives the fall, manages to come out alive through a crevasse and crawls all his way to the base camp for day.

#2 North Face (2008)

the north faceNorth Face is a movie based on the events of 1936, when two competing teams climbed the Eiger via North Face. The German climbers included Toni Kurz and Andi Hinterstoisser from Berchtesgaden.

The drama unfolds once the two German soldiers leave the Army to attempt the Eiger (falsely claiming one of them is getting married and the other is to be Best Man). The competing team of Austrians that eventually teams up with the German team are portrayed as hoping for a Nazi-led incorporation of Austria into Germany.

#3 Valley Uprising

valley uprising coverValley Uprising depicts the counterculture lifestyle of rock climbers living inside Yosemite valley. Their lifestyle was popular for dumpster-diving and wild parties that clashed with the conservative values of the National Park Service.

The movie presents the adamant rock climbers pushing their limit to climb Yosemite’s cliffs.

“Valley Uprising” is the riveting, unforgettable tale of this bold rock climbing tradition in Yosemite National Park: half a century of struggle against the laws of gravity — and the laws of the land.

Directed by Peter Mortimer

#4 Meru (2015)

Meru coverMeru is a documentary film chronicling the first successful ascent of the “Shark’s Fin” route on Meru Peak. After attempting but failing to summit Meru in 2008, famed climber Conrad Anker, Jimmy Chin, and filmmaker/photographer Renan Ozturk returned to ascent the mountain. A 2,000 meters wall known as the “Shark’s Fin” is toughest part of the climb.

The movie presents both the attempts made by the team. The 2008 expedition which failed and the 2011 expedition which went successfully.

Directed by Jimmy Chin, Elizabeth Chai Vasarhelyi

#5 The Wildest Dream (2010)

the wildest dream coverThe Wildest Dream is a docudrama based on the 1924 British expedition of the Mount Everest, when the climbers George Mallory and Andrew Irvine disappeared in the mountain.

The movie presents two different stories; one about climber Conrad Anker returning to the Everest to investigate Mallory’s disappearance and the other a biography of Mallory told through letters and archival footage from 1924. It is one of the most appreciated movies among the moviegoers.

Entertainment in August 2010 as The Wildest Dream: Conquest of Everest. The film was released in the UK by Serengeti Entertainment in September 2010 as The Wildest Dream.

Types of Climbing Rope

Rope is one of the most essential gears for any climbing activity. Learning about the durability and resistance of each types of ropes can ease off your work and even save you in the nick of time. Here is the list of modern ropes available in the market and their usages.

#1 Dynamic

A dynamic rope is a somewhat elastic rope used primarily in the climbing, such as; mountaineering, rock-climbing and boldering. The greater stretch allows a dynamic rope to absorb the energy of a sudden load,  which is quite common during the climbing.

The sudden fall or the heaving loads of the climbers can counter-react on the rope’s strength, therefore, dynamic ropes helps ease such loads and lessen the chances of breakage.

Kernmantle ropes are the most common type of dynamic rope, and nylon has replaced all natural materials such as hemp since 1945 for durability and strength.

Dynamic rope
Dynamic rope

The modern ropes are mostly made from Nylon, which requires less maintenance, and rated by the UIAA for certain standards and testing. They come in a variety of lengths and diameters, with the most common lengths being 50, 60, and 70 meters.

Ropes that are frequently used are often inspected for cuts, abrasions, or frayed areas; any cut or fraying that passes into the core of the rope is cause for concern. Ropes can also be washed to clean them of any extensive dirt or grime.

Single rope

Single ropes are designed to be used alone, and are by far the most common, and used for top-roping, sport climbing, and trad climbing.

Half rope

Half ropes are also used as a pair, but only one rope is clipped through each piece of protection- the climber alternates which rope is clipped through each piece. On wandering routes where protection is placed far apart on either side, half ropes can significantly reduce rope drag.

Twin rope

Twin ropes are used by treating the pair of ropes as a single rope, clipping both ropes through the same carabiner at each piece of protection. Twin ropes share many of the advantages and disadvantages that half ropes have compared to single ropes

There are all-purpose dynamic ropes available too which can be used for all the climbing purposes.

#2 Static

Static rope
Static rope

A static rope is designed not to stretch when placed under load, and are mostly used for rescue operations, lifting the loads and caving etc.

The static ropes have fewer purposes during the climbing and are restricted to certain applications. It isn’t recommended to use static ropes during any form of climbing, except abseiling.

Climbing Essentials

Check out the complete list

  • Alpine Climbing Harness – A good climbing harness should be light and simple in design, easy to put on and take off with gloves on, with positively foolproof locking features.
  • Crampons – Crampons must fit boots perfectly; steel crampons with anti-balling and ability to toe point positively and safely into ice. The lighter the better – extra weight on your feet is much more strenuous than anywhere else on your body.
  • Ice axe – Ice axe should be versatile and light. A general purpose technical ice axe (T rated) but not too aggressive.
    Ascender: Ascender or Jamar, a mechanical device used for ascending on a rope; must be suitable to be used with gloves or mittens. Practice using it with thick gloves on again and again.
  • Multi-LED Head Lamp – Multi-LED Head Lamp and spare batteries are essential; we do not recommend single bulb lights due to lower reliability
  • Carabiners – Minimum 2 locking carabineers, 1 large and 1 small and 4 regular.
  • Rappel Device – Figure 8, ACT or similar; be familiar with Munter Hitch as it may save your life if you lose your rappel device (which happens a lot)
  • Trekking Poles – Very handy for the approach; adjustable types are the best (preferably with a simple outside locking mechanism)
  • Slings – One 3m(10ft) and three 2m(6ft)
  • Prusik loops – Never hurts to carry a few (e.g. 0.6m and 1.2m), they come in handy in many situations
  • Masks, hoses, and regulators – Good quality for your safety.
  • Altimeter – ABC watch or more advanced GPS watches will do the trick. Watch for battery life
  • Climbing helmet – Climbing helmet is essential safety gear for crossing areas under rocks and ice cliffs; light weight is essential.
Upper Body
  • 1-2 (medium insulation) short-sleeve Merino shirt(e.g. Icebreaker Merino 150 or lightweight 200, Odlo Revolution medium)
  • 2 long-sleeve Merino shirts (e.g. Icebreaker Merino 150 and/or 200 or Odlo Revolution, one medium and one thick)
  • One fleece pullover, medium weight.
  • One fleece jacket.
  • One hardshellwaterproof Gore-Tex jacket with large hood to accommodate the climbing helmet. The Arc’teryx SV range is expensive but offers excellent wind and water protection.
  • Lightweight down jacket for chilly days in base camp or warm layer when stopping for short breaks.
  • One very warm expedition grade goose-down (duvet) jacket with hood or a down suit if you prefer, for high altitude use (e.g. Northface, Rab etc.)
  • One pair lightweight liner gloves. These will be worn when tying knots etc.
  • Mitten: Goretexovermitts (that block the wind) matched with the very warm down mitts, spare mitts might also be useful (For instance, Mountain Equipment Redline)
  • Warm wool or synthetic hat that covers your ears
  • Balaclava or face mask
  • Scarf or neck sleeve
  • Bandana or head scarf is useful for dusty conditions

  • Two Pair of liner socks. Polypropylene or wool
  • Vapour barrier liner socks or plastic bread-bags (matter of preference)
  • Two pair lightweight trekking socks, poly or wool
  • Light Merino wool or cotton socks for in town

The Island Peak

Island Peak is one of the most climbed mountains in Nepal, mainly for its easier technical accessibility and lesser altitude.


Island Peak or Imja Tse at 6,189 meters is an Alpine PD+ peak mainly know for the sports climbing.

It was named ‘Island Peak’ by the Erik Shipton’s party in 1951, because it seemed like an island floating in the sea of ice when seen from Dingboche.

Eric Shipton
Eric Shipton

Located at the Khumbu region of Nepal; which is also known for possessing Mount Everest, Lhotse, Ama Dablam and countless other peaks, Island Peak accounts for a fairly easy climb and can be done by amateurs as well as experts.

The ascent mostly requires scrambling and ice-axing skills. Cramponing becomes essential during the Ice wall climbing and thick snow areas.


Imja Tse summit was first climbed in 1956 by a Swiss team as a training exercise in preparation for Mount Everest and Lhotse. Since then, it has been climbed thousands of time by hundreds of climbers, mainly for sports, training or serious climb.


  • The summit attempt from Base Camp (BC) avoids a night spent at Advanced Camp (AC) that, during high season, can get overcrowded. It may be necessary to negotiate with other groups before leaving BC in order to ensure that there is a space to pitch your tent at AC.
  • An ascent from BC requires a very early start (midnight or earlier) and often means a very late finish (sometimes in the dark). This option should only be considered by fit groups who are well acclimatized.
  • Ascending from AC means you can start at 2 am and still descend in daylight.
  • If you stay at AC you will need to take water, food and camping equipment with you. There are no toilets.
  • Some people actually enjoy the experience and the atmosphere at the AC! It allows you to feel closer to the mountain and its environment and the surrounding scenery is very beautiful.

Peak Climbing

Ascent profileIn order to reach the summit you’ll be expected to be able to climb to Scottish Grade II standard (steep snow, possible use of two ice tools, possible difficult cornice exit, but technical difficulties are short) or Alpine PD (some technical climbing and complicated glaciers).

It can generally be climbed during two different seasons. Spring lasts from February to June, and Autumn lasts from September to November.

The place can be really crowded during these two occasions, and most climbing takes place in groups to avoid hassle. It’s easier to climb the Island peak compared to most other smaller peaks, and is generally completed within a day, however, one must need to comprehend the basic skills of ice-axing, cramponing and staying fit. Trekking can be a great opportunity to get in shape and imbibe the local environment for the climb.

Trekking Peaks in Nepal

Trekking peaks are the smaller peaks in Nepal which were opened for recreational climbing and training. They are called “Trekking Peaks,” because they mostly require trekking with minimal climbing to reach the summit, and are different than premier mountaineering. Small peaks can be climbed with ease and do not require lengthy Expeditions.

Nepal Mountaineering Association (NMA) has classified 33 such peaks as the Trekking Peaks; which are are lesser than 7,000 meters in altitude. Currently there are 326 peaks open for climbing in Nepal.

To encourage climbing, NMA has removed the royalty fee from the peaks which are lesser than 5,800 meters in height.

These peaks are divided into two groups. Most of them open for climbing during Spring (March-June) and Autumn (September-November) seasons.

Altitude Sickness & Its Possible Remedies

Altitude Sickness is a common occurrence during the travel to the higher altitude. A human body can take only a minor exposure to low partial pressure of Oxygen at higher altitudes. It is a pathological condition popularly known as AMS (Acute Mountain Sickness).

If not cured or prevented, it can advance to HAPE or HACE, which are highly fatal and hardly curable. HAPE or High Atitude Pulmonary Edema is a rare case caused by fluid accumulation in lungs, whereas, HACE or High Altitude Chronic Edema is a caused when brain is swelled with fluid.

Altitude & Oxygen

The availability of Oxygen is inversely proportional to the altitude. The higher you go, the lesser the oxygen is available.

The human body can perform best at sea level, where the atmospheric pressure is 101’325 Pa or 1013.25 millibars (or 1 atm, by definition). The concentration of oxygen (O2) in sea-level air is 20.9%, so the partial pressure of O2 (pO2) is 21.136 kPa. In healthy individuals, this saturates hemoglobin, the oxygen-binding red pigment in red blood cells (RBC).

As you ascend up, the level of Oxygen saturation in air starts decreasing, hence producing lesser Hemoglobin in RBC. To tackle such conditions, travelers usually spend more time acclimatizing to the altitude before advancing further.

Chart depicting the Oxygen level at various altitudes


  • It’s a common phenomenon during trekking or climbing at higher altitudes.
  • Most climbers are known to have died from AMS or HAPE/HACE on Mount Everest.
  • Most trekkers attract altitude sickness above the height of 3,000 meters, however, it is very rare and most of the time can be avoided with precautions.
  • Once you attract AMS, you should immediately start descending to prevent the condition from worsening. If you stay put or try ascending further, you can probably die from it.
  • The climbers at the higher altitudes are known to have hallucinated to their death due to lack of Oxygen. (Gunther Messner, brother of Reinhold Messner, at Nanga Parbat was hallucinating before dying).
  • The region above 8,000 meters is known as “Death Zone,” because, your body cannot acclimatize at the given altitude at any condition. Climbers during the summit of Eight-Thousander, such as; Everest & K2, spend as less time as possible above 8,000 meters. They basically camp below 8,000 before summiting and get back quickly below the given altitude after summit to avoid any further harm to themselves.

Remedies for Altitude Sickness

  1. Ascend slowly at the higher altitude. Take a rest or acclimatize in between to adjust yourself. The body needs a full day rest to acclimatize for every 1,500 meters of ascend.
  2. Do not ascend over 3,000 meters in a single day. you body is attuned to such high ascend in a single day.
  3. Take enough fluid, water, and protein-carb rich food to help you fight fatigue and dehydration. Carbohydrate is known to fight AMS and help store energy, therefore, carb rich food en trail is recommended.
  4. Take prophylaxis medicine after the consultation with your doctor. Acetazolamide (Diamox) is a diuretic, which increases urine production, and is known to cause an increase in respiratory ventilation that allows more oxygen exchange in our body. Take it before the trip and at the interval of 6-12 hours until you are fully acclimated.
  5. Test your RBC!  If you are found to have anemia or low red blood cells, your doctor may advise you to correct this before going on a trip. Lesser RBC in a body produces lesser hemoglobin which is essential for fighting fatigue.
