The Gondogoro La Trek is the most complete mountain journey in Pakistan. It begins at Askole on the edge of the Karakoram, follows the Baltoro Glacier all the way to Concordia and K2 Base Camp, then crosses the Gondogoro La pass at 5,585 metres into the Hushe Valley on the other side. Unlike the standard K2 Base Camp Trek, which returns on the same route, this crossing is a genuine one-way traverse: you enter through one valley and exit through another, with the full panorama of the Karakoram spread across both approaches.

This guide covers everything you need to plan the Gondogoro La Trek for 2025: the full route, elevation profile, pass crossing logistics, best season, technical demands, permits, and how to get there.

Trek Overview

The standard Gondogoro La Trek runs from Askole in the Braldu Valley to Hushe in the Hushe Valley, crossing the Baltoro Glacier, visiting Concordia and K2 Base Camp, then crossing the Gondogoro La. Total duration is 18 to 21 days from Skardu. The route is a one-way traverse, so logistics require a vehicle at both ends: jeep from Skardu to Askole at the start and jeep from Hushe back to Skardu (via Khaplu) at the end.

What makes the Gondogoro La Trek exceptional is the combination of two completely different valley systems in a single journey. The Baltoro approach is massive in scale: long glacier days, big moraine, enormous peaks on all sides. The Hushe Valley descent is narrower, greener, and faster, with the agricultural terraces and villages of Baltistan appearing below as you drop from the high pass. The transition between these two landscapes, made in a single day on the pass crossing, is one of the defining experiences in Karakoram trekking.

The Route: Day by Day

The Gondogoro La Trek follows the K2 Base Camp route as far as Concordia, then adds the pass crossing and Hushe Valley descent. The total route from Skardu to Hushe, including the flight or drive to Skardu, runs to approximately 21 days for most groups.

Days 1-2: Islamabad to Skardu

Fly from Islamabad to Skardu (approximately 55 minutes) or drive the Karakoram Highway over two days. Spend one full day in Skardu for permits, porter arrangements, and gear checks. The Skardu bazaar is the last place to buy any forgotten equipment at reasonable prices.

Day 3: Skardu to Askole (3,050m)

Jeep to Askole via the Braldu Valley: 6 to 8 hours on an increasingly rough road. Askole is the last permanent settlement before the glacier. Porters are hired here, loads are packed and distributed, and the trek briefing takes place. Camp in Askole for the night.

Day 4: Askole to Jhola (3,300m)

The first trekking day follows the Braldu River on stony trail through a wide, arid valley. Around 5 to 6 hours of walking on relatively flat ground. The Trango Towers appear on the northern horizon before camp.

Day 5: Jhola to Paiju (3,400m)

Continue along the valley floor to Paiju, the last campsite with trees and vegetation before the glacier. 5 to 6 hours. Paiju marks the psychological start of the serious section of the trek, with the Baltoro Glacier beginning just beyond camp.

Day 6: Rest Day at Paiju

A full rest day for acclimatisation at 3,400m. Use this time to walk up the hillside above camp for views of the lower Baltoro and the Cathedral Towers. Porters sort loads for the glacier section.

Day 7: Paiju to Urdukas (3,900m)

The first glacier day. From Paiju the trail climbs the lateral moraine and steps onto the Baltoro Glacier itself, one of the longest non-polar glaciers on earth at 63 kilometres. The Trango Towers dominate to the north. Urdukas camp sits on a rock shelf above the ice with wide views in every direction. 6 to 7 hours.

Day 8: Urdukas to Biange (4,200m)

Continue on the glacier moraine deeper into the Karakoram. Masherbrum (7,821m) dominates the southern skyline from Biange camp. Altitude effects begin to appear at this elevation for some trekkers. 5 to 6 hours of rough moraine walking.

Day 9: Biange to Concordia (4,600m)

Arriving at Concordia is the emotional centrepiece of the trek. The flat basin at the junction of the Baltoro and Godwin-Austen glaciers is ringed by K2, Broad Peak, Gasherbrum I, and Gasherbrum IV. The scale and concentration of 8,000-metre peaks is unlike anywhere else on earth. Two nights here for acclimatisation. 5 to 6 hours.

Day 10: Acclimatisation at Concordia / K2 Base Camp Day Trip

Most groups make the 6-kilometre walk up the Godwin-Austen Glacier to K2 Base Camp (5,150m) on this day, returning to Concordia for the night. The full south face of K2, including the Abruzzi Spur, fills the view on the approach. This is one of the defining moments of the entire trek. Return to Concordia: 5 to 6 hours round trip from camp.

Day 11: Concordia to Gondogoro La Base Camp (4,950m)

From Concordia, the route heads south toward the Gondogoro La. The base camp below the pass sits at approximately 4,950m on a moraine bench with a clear view of the pass route above. The Vigne Glacier approach is straightforward in good conditions. 4 to 5 hours.

Day 12: Cross Gondogoro La (5,585m) to Ali Camp (4,750m)

The pass crossing is the technical crux of the entire trek and begins before dawn. A 3:00 to 4:00 a.m. start is standard to cross the steepest snow slopes before the sun softens them and increases avalanche risk. Fixed ropes are in place on the upper section in season, and crampons with an ice axe are required for trekkers. The summit of Gondogoro La at 5,585m offers a panoramic view encompassing K2, Broad Peak, Gasherbrum I, Gasherbrum II, and Masherbrum simultaneously. The descent into the Hushe Valley is steep and requires careful footwork on the upper snow before the trail eases onto rock and moraine lower down. Camp at Ali Camp in the upper Hushe Valley. 8 to 10 hours total.

Day 13: Ali Camp to Saicho (3,500m)

Descend the Gondogoro Glacier moraine into the Hushe Valley. The landscape changes character completely from the Baltoro: narrower, with more vegetation appearing as you lose altitude. Saicho is a settlement in the upper valley. 5 to 6 hours.

Day 14: Saicho to Hushe (3,100m)

Final trekking day to Hushe village, where jeeps wait for the drive back to Khaplu and Skardu. Hushe is a compact Balti village with guesthouses and the first proper infrastructure since Askole. 4 to 5 hours of descent.

Days 15-16: Hushe to Khaplu to Skardu and Departure

The jeep drive from Hushe to Skardu via Khaplu takes 4 to 5 hours. Allow one or two nights in Skardu before the flight to Islamabad as buffer for weather-related delays.

The Gondogoro La Pass Crossing

The Gondogoro La pass crossing at 5,585 metres is what separates this trek from the standard K2 Base Camp route. It is the reason the Gondogoro La Trek is classified as more demanding, more logistically complex, and more rewarding than any out-and-back glacier trek in the Karakoram.

Technical Conditions on the Pass

The upper section of the Gondogoro La is a steep snow and ice slope of approximately 40 degrees gradient for several hundred metres. Fixed ropes are maintained on this section each season by local guiding organisations. All trekkers must use crampons and carry an ice axe for the crossing. A basic understanding of how to use these tools (self-arrest position, crampon technique on steep ground) is required before attempting the pass.

The most dangerous aspect of the crossing is not the gradient but the timing. The sun hits the upper snow slopes by mid-morning, softening the surface and increasing avalanche and rockfall risk from above. Groups that are not on the summit of the pass by 7:00 to 8:00 a.m. are in a significantly riskier position. An early start (3:00 to 4:00 a.m.) is not optional.

What You See from the Top

The summit of the Gondogoro La provides one of the most complete panoramas of the Karakoram range available from a non-technical walking route. K2 (8,611m), Broad Peak (8,051m), Gasherbrum I (8,080m), Gasherbrum II (8,035m), and Masherbrum (7,821m) are all visible simultaneously from the pass. No other accessible vantage point in the Karakoram places five 7,000-to-8,000-metre peaks in a single view.

When the Pass Is Closed

The Gondogoro La typically opens in late June, when snow conditions stabilise after winter accumulation. It closes again in September as early season snowfall makes the upper slopes unpredictable. Trekking groups that arrive at the pass base camp in poor weather should wait for a clear weather window rather than attempting the crossing in cloud, wind, or fresh snow. A single day of bad weather at pass base camp is common; two or three consecutive bad days are rare but possible.

Best Time to Visit

The Gondogoro La Trek has a shorter operational window than the standard K2 Base Camp Trek because of the technical pass crossing requirement.

Late June to Mid-July

The pass typically becomes crossable in the third week of June. Snow conditions are firmer in June and early July, making the upper slopes more stable. The glacier surface is snowier and route-finding on the lower moraine requires more care. Groups with previous crampon and technical alpine experience do well in this window. The Baltoro sees fewer people at this time of year.

Mid-July to Early August (Recommended)

The best overall window for the Gondogoro La Trek. Weather on the Baltoro is at its most stable, fixed ropes on the pass are well maintained by the season's first groups, and the upper snow slopes are in predictable condition. This is also when K2 and other expedition peaks see summit attempts, making Concordia particularly active.

Mid-August to September

Late season. The pass is still crossable but conditions become less predictable as autumn snowfall starts earlier at altitude. Post-monsoon moisture occasionally pushes into the Karakoram from mid-August. Groups completing the trek in this window should factor in additional weather buffer days at pass base camp.

Difficulty and Technical Requirements

The Gondogoro La Trek is rated very strenuous and includes technical alpine terrain on the pass crossing. It is not suitable for first-time high-altitude trekkers or those without prior crampon experience.

Physical Demands

The demands of the Baltoro approach (12 to 14 days of 6 to 8 hour walking days on rough glacier moraine carrying a 10 to 15 kg pack) are identical to the K2 Base Camp Trek. The pass day adds a 3:00 a.m. start and 8 to 10 hours of high-altitude physical exertion on steep terrain. The total trek is genuinely exhausting and should not be underestimated.

Technical Skills Required

  • Crampons: Must be worn for the upper snow and ice section of the pass. Experience with crampon use on steep ground is required before the trek.
  • Ice axe: Carried by all trekkers for the pass section. Basic self-arrest technique is necessary.
  • Fixed rope use: The upper 200 to 300 metres of the pass uses fixed ropes. Ability to clip into and ascend fixed lines is required.
  • Cold weather tolerance: Temperatures at the pass before dawn will be -10C to -20C depending on the year and season.

Trekkers without prior crampon experience can prepare by taking a one-day alpine skills course at a climbing school before departure. The technical skills required for the Gondogoro La are entry-level by mountaineering standards but critical for safe passage. Your licensed guide will assess conditions and provide instruction on the day.

Altitude

Maximum altitude of 5,585m on the pass is 435 metres higher than K2 Base Camp. The acclimatisation profile of the Baltoro approach (progressive elevation gain with rest days at Paiju and Concordia) is well-designed for this altitude. Trekkers who respond well to the elevation at Concordia generally manage the pass crossing without significant altitude problems. Diamox should be discussed with your physician before departure.

Permits and Regulations

The Gondogoro La Trek requires the same permits as the K2 Base Camp Trek, as the route covers the same Baltoro Glacier zone, plus an additional permit for the Hushe Valley exit.

  • Baltoro/Concordia Trekking Zone Permit: Required for all foreign trekkers on the Baltoro Glacier. Arranged through your licensed operator.
  • Gondogoro La Permit: A separate permit is required specifically for the Gondogoro La pass crossing. Cost approximately USD 50 per person.
  • Central Karakoram National Park Entry: Both the Baltoro and Hushe Valley sides fall within CKNP. Entry fees apply.
  • Porter and Guide Registration: All staff must be registered in both Askole (Skardu district) and Hushe (Ghanche district). Your operator manages this.

The logistics of porter transitions on the Gondogoro La are handled by your operator. Porters from Askole typically do not cross the pass; a new set of porters from Hushe will meet your group at Ali Camp or Saicho for the descent to Hushe village. Confirming this handover arrangement with your operator before departure is important.

Getting There: Skardu and Hushe Valley

To Skardu: Fly or Drive

Fly from Islamabad to Skardu (55 minutes, subject to weather) or drive the Karakoram Highway via Gilgit (20 to 24 hours). Always build 2 to 3 days of buffer into your schedule for flight delays. Skardu is the logistics base for both the Askole approach and the Hushe return.

Skardu to Askole (Start)

6 to 8 hours by 4WD vehicle on rough track through the Braldu Valley. The road is unpaved and requires a high-clearance vehicle for the final stretch. Your operator arranges all transport.

Hushe to Skardu (End)

The return from Hushe to Skardu via Khaplu takes 4 to 5 hours on better roads than the Askole approach. Khaplu has a small bazaar, guesthouses, and the restored Khaplu Fort (now a heritage hotel), worth a stop if time allows. From Khaplu, Skardu is approximately 2 hours further along the Shyok River valley.

What to Pack

The Gondogoro La Trek requires all the standard Baltoro glacier gear plus the technical equipment for the pass crossing.

Technical Equipment (Pass Crossing)

  • Crampons: 12-point, compatible with your trekking or mountaineering boots
  • Ice axe: 60 to 70 cm standard alpine axe
  • Climbing harness: lightweight alpine harness for clipping into fixed ropes
  • Locking carabiner: one is sufficient for fixed line use
  • Prusik sling or ascender: for fixed rope sections on steep terrain
  • Gaiters: essential for the snow sections above pass base camp
  • Mountaineering boots or stiff trekking boots compatible with crampons

Standard Baltoro Gear

  • Four-season sleeping bag rated to -20 degrees Celsius
  • Down insulated jacket (600-fill minimum)
  • Hardshell waterproof jacket and trousers
  • Thermal base layers (two sets minimum)
  • Fleece mid-layer
  • Two trekking poles with spike tips
  • UV-protective sunglasses and glacier sunscreen SPF 50 or above
  • Headlamp with fresh batteries for the 3:00 a.m. pass start
  • Water purification filter or tablets
  • First aid kit with Diamox, ibuprofen, and blister kit

The Hushe Valley: What to Expect on the Other Side

The Hushe Valley is one of the most scenically dramatic valley systems in Baltistan, but it receives a fraction of the visitors that the Baltoro route sees. After crossing the Gondogoro La, the descent brings you into a world that feels completely different from the wide glacier basin you left behind.

The upper valley is rocky and desolate immediately below the pass, but within a few hours of descent, vegetation begins to appear: first sparse alpine grasses and then the lower terraced fields and poplar trees of the traditional Balti settlements. Hushe village itself is a compact farming community with stone houses, apricot orchards, and a strong local mountaineering tradition. Many of Pakistan's most celebrated high-altitude porters and guides come from Hushe.

The Hushe Valley also serves as the base for expeditions to Masherbrum (7,821m) and K6 (7,281m). If you arrive with time to spare, a rest day in Hushe before the drive back to Skardu is a good way to absorb the contrast between the two sides of the pass.

Frequently Asked Questions

Is the Gondogoro La Trek harder than the K2 Base Camp Trek?

Yes, by a significant margin. The K2 Base Camp Trek is strenuous but non-technical. The Gondogoro La Trek adds the technical pass crossing (steep snow, crampons, ice axe, fixed ropes, a 3:00 a.m. start) on top of the same long glacier approach. The pass day alone is physically and mentally more demanding than any single day on the standard K2 Base Camp route.

Do I need mountaineering experience?

You do not need summit or expedition experience, but you must have prior crampon and ice axe experience before attempting the Gondogoro La. Trekkers who have never worn crampons should complete a one-day alpine skills course before the trek. Your guide will not be able to teach crampon technique from scratch on a 5,585m pass before dawn.

Can the Gondogoro La Trek be done in the other direction?

Technically yes (Hushe to Askole), but it is almost never done this way. The standard direction (Askole to Hushe) means you ascend the steep side of the pass from the Baltoro side, which is easier with the fixed ropes. The descent on the Hushe side is steep but shorter. Reversing the route would mean ascending the Hushe side and descending the Baltoro side, which is technically feasible but less commonly serviced by porter and logistics networks.

What happens if the pass is closed due to weather?

If weather prevents a pass crossing attempt, your group will wait at pass base camp for a clear window. Your operator will have a contingency plan, which typically involves either waiting for a 24 to 48 hour improvement or returning to Concordia and descending the Baltoro route back to Askole. Travel insurance with trip interruption cover is important for this scenario.

What is the best month for the Gondogoro La Trek?

Mid-July to early August offers the most reliable combination of settled weather and pass conditions. The pass typically opens in late June. Crossing in early July is possible for experienced groups. August is generally feasible but requires more attention to late-season weather patterns in the second half of the month.

How much does the Gondogoro La Trek cost?

More than the standard K2 Base Camp Trek due to the additional Gondogoro La permit, the Hushe Valley porter logistics (second team of porters for the descent), and the extra days. A fully supported trek with a licensed operator including all permits, guides, porters, cook, and camping equipment typically ranges from USD 2,800 to USD 4,000 per person for groups of 4 to 8. Larger groups reduce the per-person cost significantly.

Do I need a guide?

Yes, and on the Gondogoro La Trek a certified guide with high-altitude and technical glacier experience is essential, not just a permit requirement. The pass crossing requires someone who knows the current fixed rope condition, can assess snow stability, and can make the call on whether to proceed or wait. This is not a route to attempt without qualified local leadership.

Is there mobile signal on the trek?

Signal exists in Askole and the Braldu Valley, then disappears completely on the glacier. There is no coverage between Paiju and Hushe for the entire crossing. Hushe village has intermittent signal. Plan to be offline for 12 to 14 days from the start of the glacier walk.

What is the Gondogoro La elevation exactly?

The Gondogoro La pass summit is at 5,585 metres (18,323 feet) above sea level. This makes it approximately 435 metres higher than K2 Base Camp (5,150m) and well above Everest Base Camp on the Nepal side (5,364m).

Can I do the Gondogoro La Trek if I have only done Everest Base Camp before?

Prior EBC experience is good preparation for the Baltoro approach, but the Gondogoro La Trek adds a technical pass crossing that has no equivalent on the standard EBC route. If your EBC experience included acclimatising well above 5,000m and you have some basic alpine skills, you are well-positioned to attempt the Gondogoro La with proper preparation. If EBC was your first mountain experience and you had significant altitude problems, speak with your doctor and operator before committing.

What visa do I need for Pakistan?

Pakistan's e-Visa is available for citizens of over 190 countries and can be processed online in 3 to 5 business days. Check current requirements for your specific nationality, as processing times and conditions vary. Your trek operator can advise on the visa application process.
