Thalle La Trek: Pakistan's easiest Karakoram pass (2026/2027)

A three-day crossing from Khaplu to Shigar over a 4,572 m pass, with no glacier and no permit. Route, altitudes, season, costs and how hard it really is.

Almost everything written about Thalle La online is a tour listing, and the listings disagree with each other. One calls it easy and suitable for families. Another calls it moderate to challenging. The trek is four days on one site and thirteen on the next. Nobody publishes an altitude for a single campsite.

Most of those numbers are defensible. They just measure different things, and none of the pages say which. What follows is the trek the way it works on the ground, with the altitudes and the hours attached.

Thalle La at a glance

On the altitude: 4,572 m is the figure every operator publishes, and it is exactly 15,000 feet, which is a giveaway that it started life as a round number in an old survey. Mapping platforms that read elevation off a digital terrain model put the crossing point nearer 4,830 m. We use 4,572 m because that is the published convention and the one your guide will quote, but do not be surprised if your watch reads higher at the top. Either way it sits well below the 6,000 m line where Pakistan's rules change.

Where Thalle La actually is

The Thalle Lungma is a long green side valley that runs north-west off the Shyok river, 15 km west of Khaplu and about 85 km east of Skardu. Driving up the right bank of the Shyok from Skardu, you turn off at Doghoni. From there a jeep road climbs roughly two hours to Thalle Broq at about 3,200 m, which is where the walking starts.

Above Thalle Broq the valley is farmed and grazed most of the way. Olmo is the highest permanent summer settlement on this side, and beyond it the valley turns to open pasture, with stone shepherd huts and animals out on the grass. Higher still the valley forks. The north branch leads to Tusserpo La at 5,084 m, a harder crossing that sees a handful of parties a year. The south branch is the one you want: Thalle La at 4,572 m. Both drop into the Bauma Lungma on the far side, which runs south-west to Shigar.

This is an old road, not a discovered one. Between 1891 and 1947 the British used Thalle La as the preferred link between Skardu and Khaplu, because unlike the river route it offered grazing the whole way for pack animals. Local traffic has been going over it a great deal longer than that.

The route, stage by stage

The trek is walked in both directions. Khaplu to Shigar is the more common way round because the climb is spread over two days from the Thalle side and the Shigar descent is short. Going the other way makes a steeper ascent and an easier finish. Your operator will pick based on where the jeeps are and how the group is acclimatising.

Some itineraries merge the first two stages and cross the pass on day two, which is why you will see the trek sold as three days and as four. Both are honest. The four-day version gives you a night at 4,100 m before the pass, and if you have flown into Skardu two days earlier, that extra night is the difference between enjoying the crossing and grinding over it with a headache.

The crossing itself is a long walk uphill on scree and grass, not a climb. In a normal season there is no ice on the trail and nothing to rope up for. What you get at the top is the reason people come: Masherbrum, 7,821 m, the peak the Survey of India labelled K1 before anyone had noticed K2, and the sharp cone of Mango Gusor at 6,288 m.

How hard is it, honestly

Easy pass, awkward access. That is the shortest true answer, and the reason the listings contradict each other is that they are grading different things.

The walking is genuinely undemanding. There is no glacier, no exposure, no rope work, and a fit fourteen-year-old manages it. Days are five to seven hours at a steady pace with a porter or pony carrying the load.

What makes it more than a stroll is everything around the walking. You sleep at 4,100 m two or three days after leaving sea level, which is enough altitude to matter if you rush the approach. The jeep roads at both ends are rough and get rougher after rain. Camps have no facilities at all, so you are carrying water treatment, a proper sleeping bag and a tent whatever the brochure photograph suggests. And the weather at 4,500 m in the Karakoram turns fast in any month.

If you have done multi-day hill walking with camping behind you, and you take the acclimatisation seriously, Thalle La is well within reach. If your last trek was a day hike, book the four-day version rather than the three.

When to go

If the views are what you came for, go in September. If you want the valley alive with animals and families at the summer settlements, go in July. Our guide to the best time to visit Skardu covers the wider regional picture, including the road and flight conditions that decide whether you reach the trailhead at all.

What it costs

Published prices for Thalle La sit between USD 1,400 and 2,100 per person for the full package from Islamabad, with most operators clustered around 1,450. Short local versions that start and finish in Skardu, with no domestic flights and no Islamabad nights, run from around EUR 400.

The spread is almost entirely about what gets counted. A full package price includes the Islamabad hotel, the Skardu flights, the jeeps at both ends, a guide, a cook, porters or ponies, all camping equipment and every meal. The cheap number is the trekking days alone. Neither is wrong, but compare them carefully before deciding one operator is expensive.

Two line items move the total more than anything else. Group size is the first: the fixed costs of a guide, cook and jeep split across two people cost roughly double per head what they cost across six. The second is the Skardu flight, which is cheap when it operates and expensive in time when it does not, because the alternative is two long days on the Karakoram Highway. Build in a contingency day at the Skardu end and you will use it perhaps one trip in three. Our guided Thalle La trek is built as an eight-day trip with that contingency day already in it, and we plan all our Skardu trips around the same flight risk.

Permits and paperwork

Thalle La needs no trekking permit. Pakistan sorts trekking areas into open, restricted and closed zones, and the Thalle valley is open. A Pakistan visa is the whole of the paperwork.

This trips people up because the far more famous Baltistan treks are not in the open zone. The Baltoro, Concordia and K2 base camp all sit inside the restricted zone, where you need a permit, a fee and a government liaison officer with the group. Several Thalle La listings quietly borrow that language and tell you a permit is required. It is not. What some of them mean is the trekking visa category, which is a visa endorsement you apply for from home, not a permit issued in Pakistan. For an open-zone trek like this one, an ordinary tourist visa is enough. The Directorate of Tourist Services, Gilgit-Baltistan publishes the current zone rules.

One practical thing does follow from the geography. Ghanche is a border district, and you will pass army check posts on the Khaplu road where passports and visas get written into a ledger. Carry photocopies, keep the originals accessible, and allow a few minutes each time. The Thalle valley itself runs west, away from the sensitive ground near the Line of Control, and is trekked without restriction.

Thalle La compared with the treks people choose instead

Read across that table and Thalle La occupies a gap nothing else in Baltistan fills. It is the only short, permit-free, glacier-free trek in the region that still puts you above 4,500 m with an 8,000 m-class skyline in front of you. If you want the full Karakoram commitment instead, our Gondogoro La trek guide sets out what that costs in days and difficulty. If you are looking for something gentler at the Skardu end, Basho valley is the other direction entirely.

What to bring

• A four-season sleeping bag. The high camp drops below freezing in any month. This is the single item people under-spec and regret.
• Broken-in boots with ankle support. The descent to Deserpa is loose scree for a long stretch.
• Sun protection at full strength. High-factor cream, lip balm, a brimmed hat and category 4 glasses. At 4,500 m on old snow the glare is punishing.
• Water treatment. Filter or tablets. The streams look pristine and run through grazing land all the way.
• Warm layers plus a windproof shell. Pass mornings are cold and windy even when the valley is hot.
• Cash in rupees. The last reliable ATM is Skardu, and it is not always reliable.

Everything else, meaning tents, mats, cooking kit and the group equipment, comes with the operator. Porters or ponies carry the load between camps, so you walk with a daypack.

Frequently asked questions

How high is Thalle La?

4,572 metres, or 15,000 feet, in the figure every operator and map caption uses. Digital elevation models put the actual crossing point closer to 4,830 m, so your watch may read higher at the top. Nothing about the trek changes either way.

How many days is the Thalle La trek?

Three days of walking, or four with a rest day at the pastures. The seven to thirteen-day figures you see advertised are whole packages from Islamabad, counting flights, Skardu, sightseeing and a contingency day for the weather.

Do you need a permit for Thalle La?

No. The Thalle valley is in Pakistan's open trekking zone, so no trekking permit, no fee and no liaison officer. A tourist visa covers it. The permit rules people quote belong to the restricted zone, which is where K2 base camp and the Baltoro sit.

Is Thalle La suitable for beginners?

For a beginner with hill-walking fitness who is willing to camp, yes, and it is the trek we most often suggest for a first Karakoram crossing. It is not a first-ever multi-day walk: you sleep at about 4,100 m and cross above 4,500 m, which needs a sensible acclimatisation plan rather than technical skill.

What is the best month for the Thalle La trek?

Late June to mid September is the window. July gives you the greenest pastures and the summer settlements in full use. September gives you the clearest air and the best view of Masherbrum, at the cost of cold nights.

Is there a glacier on the Thalle La trek?

No, and that is the point of it. Thalle La is one of very few unglaciated passes in Baltistan, which is why nobody carries a rope or crampons over it in season, and no glacier experience is asked for.

Can you do Thalle La from Skardu rather than Khaplu?

Yes. The pass is crossed in both directions and the Shigar trailhead is the closer of the two to Skardu. Khaplu to Shigar is more common because it spreads the climb over two days, but reversing it is normal and sometimes better for jeep logistics.

What will you see from the top of Thalle La?

Masherbrum, 7,821 m, which the Survey of India catalogued as K1, along with Mango Gusor at 6,288 m and the ridgelines running back towards the Baltoro. On a clear September morning the view runs for a very long way.

Is trekking in Baltistan safe?

Gilgit-Baltistan carries no travel advisory against it from either the US State Department or the UK FCDO, and the Thalle valley is farmed, grazed and inhabited for most of its length. You will pass army check posts on the Khaplu road, which is routine in a border district. The real risks on this trek are altitude and weather, not security.
