This is a strenuous guided mountain expedition to the Nepalese Himalaya to climb the famous trekking peaks of Mera Peak (6461m) and Imja Tse (6189m), a three week trip that offers two high mountains which are both achievable for someone with good alpine skills up to PD/PD+.

Both mountains offer different challenges. Mera is high but has few objective dangers like crevasses, whereas Island Peak is almost like a mini Everest in terms of its objective challenges. In fact the route we use is the same as Hillary and Tenzing used back in 1953 in preparation for their successful Everest climb. There is a headwall which is a little like a mini Lhotse Face, a narrow ridge to the top like the SE Ridge on Everest, and a short section of broken seracs and crevasses a little like a mini Icefall.

The trip can be run in either direction, with either peak being climbed first. But the approach trek makes Mera Peak the better option to be climbed first, after which we cross into the Khumbu valley over the Zetra La and continue up to Island Peak which is along the Everest trail and up the Chukkung Valley.

Mera Peak is in the Makalu Barun National Park on the edge of the Khumbu region. At 6476m this is the highest of Nepal's trekking peaks and offers fantastic views from the summit including Everest, Lhotse, Nuptse, Makalu, Ama Dablam, Chamlang and Baruntse. This peak is not very technical but still requires members to be roped together. 

Mera Peak (2)
Advanced Base Camp on Mera Peak with sleeping tents and a cook tent set up for a few days on the permanent snow. From here the ascent is not technical but it is high and challenging.

Island Peak is at the top of the Chukkung Valley and surrounded by Himalayan giants. From Mera Peak the route crosses the Zetra La into the Khumbu valley and then follows the normal Everest trail as far as Dingboche. Instead of continuing towards the next village of Lobuje which is on the Khumbu glacier, this route goes up to the village of Chukkung and then another five or six hours to the base camp. The summit is a full day starting early.

Crossing the glacier on Island Peak and heading towards the headwall which has fixed to ascend onto the summit ridge which is narrow and exposed to the summit.

Fitness, experience and terrain

Climbers should have experience of moving on a climbing rope and using fixed lines, and be familiar with multi-day high altitude trips. It is a physically demanding expedition but offers a truly amazing experience of some famous 6000m Himalayan peaks. For a detailed look at the kit required, check out our Nepal kit guide.

The best preparation for this trip is training in a way that best replicates the demands of the trip. Concentrate on cardio-vascular fitness such as running, swimming, cycling, rowing and also some specifically-targeted body-weight or free-weight workouts such as squats, calf raises, planks in combination with low-intensity long period fitness like hillwalking with a pack of around 10kgs.

The terrain is very varied. A lot of the paths in the main valleys are very pleasant and easy, some are in cultivated farmland areas and others are quite high and open. Shorts and Tshirts and a day pack and some nice weather will be enough for some perfect mountain days.

Mera Peak is not technically demanding but it is high and a long summit day, and you are of course open to the elements. Take care with hydration and maintaining a slow manageable pace. The snow route itself is not steep but it is a big day out and will sap your strength. You will need to be comfortable moving on a man rope, clipping in and maintaining an efficient pace and a safe line. Also be familiar with walking on crampons and being able to self arrest with your walking axe. We use a high camp for this peak so experience camping on the snow and keeping warm, dry, hydrated and well fed is important to ensure you're in the best shape for summit day.

Island Peak is a classic Himalayan 6000'er and a classic climb graded PD+/AD- and requires multiple skills on mixed steep ground. Initially negotiating the paths in the dark up to the snow line is not too difficult but there is a lot of loose scree and switchbacks in and out of the rocks and cliffs. Once at crampon point, the journey continues on man ropes across glaciated ground with large crevasses. There are ladders in place and the route is normally easy to follow, but confidence and competence on a rope is important. Make sure you are familiar with your harness and tying into a rope, and moving safely in a team. Crossing ladders is not too difficult but it does take a bit of nerve and balance, there are handlines to help and it's important to clip into one of these.

The headwall to the summit ridge of Island Peak is 300 metres ascent between 40 and 55 degrees and takes about three to four hours depending on how busy it is, the weather and how efficient you can move on fixed lines. The headwall can be dry which means ascending on mixed rock and ice, and it is important to check the anchors especially if the descent is in the afternoon. The route is not difficult, there are plenty of shelves and rest points, plus there are lots of anchor points to cross, first with your safety karabiner and then with your jumar.

This routine is very important, you should make yourself a cow's tail before summit day, which is essentially a jumar and a locking karabiner on two slings or pieces of rope attached to your harness. Make sure their length is enough to keep a slight bend in your arm. When climbing, always ensure the jumar and the karabiner are attached to the fixed line and always move the karabiner above the anchor point before moving the jumar over.

At the top of the headwall the summit ridge extends a further 250 metres to the small and shapely peak, and this is quite exposed and airy with amazing views looking back towards Ama Dablam. The fixed lines are still in place, but it is important not to lean back on the rope. Use the jumar as a safety device, not something to 'jug' up the rope. Be mindful of other people coming down, there is very little space (if any) for two people to cross each other so communicate and decide who goes first. 

The summit itself is small, only room for about five people comfortably, and it is a truly remarkable spot with a panorama view of some of the great peaks of the high Himalaya. Everest itself is not visible, because Island Peak is close up to the vast and dramatic south side of the Lhotse/Nuptse wall, scene of many a famous winter climb by the great Polish super climbers in the 1970s.

Coming back down again you will feel the tiredness but it's vital to be completely alert. The first section back down the ridge is exposed and at the top of the fixed lines you will need to abseil down the headwall. The initial section is the steepest and there are quite a few anchor points every 30 metres or so. This is a single line abseil with no top roping so it's important you are competent and confident in abseiling (or rappelling) by yourself. Again, make sure you use a safety karabiner on the line as well, and make sure you move it across to below the anchor before moving the descender device you are using. Make sure you don't descend on a rope with someone else on it, and always check the anchor points before carrying on. If you are coming down in the afternoon then the sun will have warmed the slope and it's quite possible that anchor such as aluminium bars or screws will have worked loose from the ice. It is absolutely vital that you personally check each anchor yourself and make your decision before descending further, and communicate to the guide if you feel uncomfortable or unsure about anything.

Note that the fixed lines on Island Peak are not normally kernmantel ropes, they are quite thin polypropylene ropes which can easily ice up in the morning. This means that the toothed cam of a jumar might slip along them. Always check the line as best you can and when you move over the anchor points just check the cam isn't iced up.

There might be two up lines, and two down lines. Inevitably if it's busy there is a lot of chat from people, some looking to overtake for example. Keep to the principles of not having multiple people climbing on a fixed line and putting undue pressure on the anchor. Communicate clearly and don't shout or get annoyed!

Whilst it could be -20 on an early morning start or on the summit, it could also be +20 or more with strong UV in the valley. It is likely therefore that you will leave the tent in the morning in maybe; mountain trousers, baselayer, warm mid-layer, soft-shell, down jacket, windproof layer, two hats, gloves and over-mitts. By the time you return in the early afternoon you may be wearing just mountain trousers, thin long sleeved baselayer top, sun hat & sun glasses with everything else stuffed into your daysack.
