The Biafo-Hispar traverse is widely considered one of the greatest long-distance glacier treks on Earth. Connecting Askole in the Baltoro corridor to Hispar village in the Nagar Valley via the Snow Lake plateau at 5,128 metres, this eighteen-day point-to-point journey crosses two of the world's largest mountain glaciers outside the polar regions. The Biafo Glacier stretches 67 kilometres from Askole to the Snow Lake plateau, and the Hispar Glacier runs a further 49 kilometres from Snow Lake to the Nagar Valley. Together they form a single 116-kilometre glacial highway through the uninhabited core of the central Karakoram - an ice world of extraordinary beauty, silence, and scale that has captured the imagination of explorers since Martin Conway first traversed the route in 1892.
The traverse is a one-way journey starting in Askole and ending in Hispar. From Askole, the trail follows the Biafo Glacier northeast for six to seven days through progressively more remote terrain, passing the Uzun Brakk base camp area and the spectacular granite spires of the Latok group before opening onto the vast Snow Lake plateau. Snow Lake is not a lake but a high cirque of permanent snow and ice surrounded by unnamed peaks above 6,000 metres, filling the sky in every direction with a pure white landscape unlike anything else in the Karakoram. From Snow Lake, the crossing of the Hispar La (5,151m) descends onto the Hispar Glacier for a further five days of glacier travel to Hispar village and the Nagar Valley road.
Snow Lake sits at the centre of the traverse at 5,128 metres and represents the emotional and physical climax of the journey. The plateau is surrounded by the Latok peaks, Baintha Brakk (the Ogre), Sosbun Brakk, and dozens of unnamed summits above 6,000 metres. The sheer scale of the cirque, and the complete absence of any human infrastructure or sound, creates an experience of wilderness purity that very few places on Earth still offer. Camping at Snow Lake on a clear night, with the snow glowing blue in the moonlight and peaks rising 1,000 metres above the plateau rim, is one of the defining high-altitude experiences in world mountain travel.
The Biafo-Hispar traverse is only feasible from late June through early September. The Snow Lake plateau and Hispar La crossing require stable snow conditions that are only reliable in this window. July is the most popular month with the longest daylight hours. August sees the most expedition traffic and the most established trail markings on the upper glacier. The traverse should not be attempted in June without local guide confirmation of conditions, as crevasse bridges on the Biafo can be dangerously weak in early season.
This is a demanding trek graded as strenuous. Trekkers must have prior multi-day high-altitude experience and the physical capacity for six to eight hours of glacier travel daily over sustained periods. The Hispar La crossing at 5,151 metres requires crampons and ice axe, which are provided as group equipment. Navigation on the upper Biafo and Hispar glaciers requires guide experience as crevasse fields can make route-finding dangerous without knowledge of the terrain. This is not a route for beginners, and World of Mountain requires prior trekking experience above 4,000 metres from all participants.
The Baltoro Glacier and K2 Base Camp route is rightly famous, but the Biafo-Hispar traverse offers something the Baltoro cannot: true solitude. The number of trekkers completing this route each year is a small fraction of the Baltoro traffic, and for long sections of the upper Biafo and Hispar glaciers you may not see another party for days. For experienced trekkers seeking the ultimate Karakoram wilderness experience without the expedition permits, high altitude camps, or technical climbing of an 8,000-metre objective, the Biafo-Hispar Snow Lake traverse is the definitive answer.

Arrive in Islamabad and transfer to the hotel. Evening briefing covers the complete traverse: the Biafo approach, Snow Lake, Hispar La crossing, and the Hispar descent. Equipment audit and porter kit distribution plan reviewed. Welcome dinner with your lead guide.
Early morning flight to Skardu with views of the Karakoram. Afternoon acclimatization walk and final equipment check. The camp cook reviews the food inventory for eighteen days on the glacier. Rest and early bed.
Jeep drive along the Braldu Gorge to Askole, the last village before the Biafo Glacier. Permit formalities with the ranger station. Camp in Askole and meet the full porter team. The Biafo Glacier entrance is visible at the head of the valley from camp.
Step onto the Biafo Glacier for the first day of the traverse proper. The Biafo's lower section is a broad highway of grey ice with lateral moraines on either side. Namla camp on the northern moraine marks the first night on the glacier. The isolation begins here - no roads, no villages, nothing but ice and sky ahead for twelve days.
Continue up the Biafo, the glacier ice becoming progressively cleaner and more complex as altitude is gained. Marpogoro camp is a flat moraine area on the southern side of the glacier with good views back down the valley toward Askole. The Latok peaks begin to appear in the distance to the north.
Baintha camp sits beneath the extraordinary Latok group - Latok I (7,145m), Latok II (7,108m), and Latok III (6,949m) - whose granite north faces rise sheer above the glacier. These peaks are among the most technically demanding in the Karakoram and their unclimbed routes have defeated some of the world's best alpinists. The camp atmosphere is one of awe at the scale of the surrounding peaks.
The Biafo glacier narrows and its surface becomes more complex above Baintha as the ice is compressed between converging valley walls. The Ogre (Baintha Brakk, 7,285m) appears ahead, its serrated summit ridge one of the most technically demanding peaks in the world. Camp on the upper Biafo moraine with growing views toward the Snow Lake plateau still two days ahead.
A mandatory rest day on the upper Biafo before the final push to Snow Lake and the altitude gains ahead. Spend the morning on a short acclimatization walk onto the glacier to test crampon technique. The guide assesses team fitness and SpO2 levels. Photography, journaling, and rest fill the afternoon at one of the most remote camps on the traverse.
The glacier flattens and widens dramatically as the Snow Lake plateau comes into view ahead, the horizon expanding in every direction as the confining valley walls recede. Navigation on this section requires the guide's knowledge of the crevasse systems hidden beneath the apparently flat surface. Camp at the edge of the Snow Lake plateau as the sky turns extraordinary colours at sunset over the surrounding peaks.
A full day on the Snow Lake plateau at 5,128 metres. The sheer scale of the cirque - completely surrounded by peaks above 6,000 metres and filled with unbroken white from horizon to horizon - is something that photographs cannot fully communicate. Walk the perimeter of the plateau with your guide, identifying peaks and glacier flows. This is the highest point of the traverse and one of the great wilderness experiences available anywhere in the trekking world.
Cross the Snow Lake plateau toward the Hispar La, the high pass that marks the watershed between the Biafo and Hispar glacier systems. The approach to the pass is across a broad snow field that requires steady navigation. Camp at the base of the final Hispar La headwall with the pass visible above in the afternoon light.
The Hispar La crossing begins early. Crampons on, the team ascends the snow slope to the col at 5,151 metres with full views back across Snow Lake and ahead down the Hispar Glacier to the Nagar Valley far below. The descent on the Hispar side is steep on loose moraine before stabilising on the glacier surface. This is the technical highlight of the traverse. Camp on the upper Hispar with the sense of having crossed from one world into another.
Begin the long descent of the Hispar Glacier, now moving with the slope for the first time on the traverse. The Hispar's ice architecture differs markedly from the Biafo - more chaotic seracs and larger meltwater channels that require careful route-finding. The valley begins to widen ahead as the Nagar Valley approaches. Camp on the lower Hispar moraine.
Continue down the Hispar through Bitanmal camp, one of the few flat camping areas on the lower glacier. The ice becomes dirtier with moraine debris as the glacier snout approaches. The first signs of vegetation - scrub grass and willow bushes - appear on the lateral moraines, a welcome return of green after days on pure ice and snow.
The final trekking day on the glacier ends when the Hispar snout gives way to a rough trail descending through moraine and scrub to Hispar village at 3,100 metres. The first apricot trees and stone houses of Hispar appear after fifteen days of ice, rock, and snow. A deeply emotional return to human habitation after one of the great mountain wilderness traverses.
Jeep drive from Hispar down the Nagar Valley to Nagar town and on to a guesthouse near Karimabad with hot showers and clean beds. The drive passes through the same apricot terraces and Nagar villages that appear on approach to Rakaposhi Base Camp. Porter farewell ceremony in Hispar village before departure.
Full rest day in Nagar or Gilgit for physical recovery and celebration. The lead guide conducts a formal traverse debrief, reviewing the route, conditions, and individual achievements. Evening celebratory dinner with traverse completion certificates presented to all team members.
Morning flight from Gilgit to Islamabad. The Biafo-Hispar Snow Lake Traverse is complete - 116 kilometres of glacier, Snow Lake at 5,128 metres, the Hispar La crossing at 5,151 metres, and eighteen days in one of the world's last true wildernesses. Airport transfer and assistance with international departures provided.
The Biafo-Hispar Snow Lake Traverse is the most physically demanding trek in the World of Mountain portfolio. Eighteen consecutive days of glacier travel with multiple days above 4,500 metres requires a level of fitness and endurance that cannot be improvised on the mountain.
Begin a structured training programme at least ten to twelve weeks before departure. Long-distance hiking with a loaded pack (10-12kg) is the most specific preparation - aim for weekly long days of eight hours or more on varied terrain. Stair climbing, cycling, and running build the cardiovascular base needed for sustained glacier days. Core and back strength training directly reduces fatigue from pack carrying over the length of the traverse. Trekkers who have completed the K2 Base Camp Trek or Gondogoro La Trek are well-prepared for this route.
The traverse reaches 5,151 metres at the Hispar La and spends three days above 4,600 metres around the Snow Lake plateau. The gradual six-day Biafo approach from 3,015 metres to 5,128 metres provides effective natural acclimatization that is built into the itinerary.
Eighteen days on two major glaciers demands equipment that is durable, weatherproof, and appropriate for the specific conditions of the Biafo and Hispar glacier systems.
There is no resupply opportunity between Askole and Hispar village. All food for eighteen days must be carried from Askole by the porter team. This logistical reality makes the Biafo-Hispar traverse one of the most complex food planning exercises in Karakoram trekking.
The World of Mountain camp cook prepares three cooked meals daily using a combination of fresh produce (consumed in the first four days), dried and preserved foods for the glacier section, and high-calorie speciality foods for the Snow Lake and Hispar La days. Freshwater is available throughout the traverse from glacier meltwater streams. Water from the glacier surface is filtered and treated by the cook team before use. Personal energy snacks, chocolate, nuts, and sports nutrition should be carried in your daypack for daily consumption between meals.
The Biafo-Hispar glacier corridor is one of the last genuinely pristine wilderness trekking routes in the Karakoram. The very low number of trekkers who complete this route each year is its greatest ecological asset. Every trekker who passes through has a responsibility to keep it that way.
The Biafo-Hispar traverse passes through one of the most remote landscapes accessible by a trekking party in the entire Karakoram range. A clear and comprehensive emergency plan is part of every World of Mountain traverse briefing.
The lead guide carries a satellite phone with pre-programmed contacts for emergency services in Skardu and Gilgit, the World of Mountain office, and the Pakistan Army Aviation Corps helicopter rescue coordination number. Emergency landing zones are identified at Baintha camp on the Biafo and at Bitanmal on the Hispar - the only points on the traverse where helicopter access is potentially feasible. A full first aid kit, emergency oxygen, and a written medical protocol for altitude emergencies are carried throughout. All trekkers must nominate an emergency contact at home before departure.
