Tilicho Lake Route Map: Stages, Distances & the Landslide Traverse

The Route in One Paragraph

Most trekkers now start by driving up the Marsyangdi valley to Chame (2,670 m), since the road has swallowed the lower circuit. From there you walk to Upper Pisang (3,300 m) and take the high route via Ghyaru and Ngawal to Manang (3,540 m), the trading hub of the upper valley and the standard acclimatisation stop. The Tilicho branch leaves the circuit here: west to the last permanent village of Khangsar (3,734 m), then across the notorious landslide traverse to Tilicho Base Camp (4,150 m). From base camp it is a long pre-dawn climb to Tilicho Lake (4,919 m) and back down the same way. You then retrace the traverse and rejoin the circuit at Yak Kharka (4,050 m), continuing to Thorong Phedi (4,500 m) or High Camp (4,925 m) before crossing Thorong La (5,416 m) to Muktinath (3,760 m) and out via Jomsom (2,720 m).

The lake itself is an out-and-back from base camp. Everything else is part of the Annapurna Circuit, which is why the two treks are best understood as one trip with an optional high detour.

Standard Route Table (Tilicho plus Thorong La)

Distances are approximate and depend substantially on where the jeep drops you, which changes as the road extends. Walking hours assume a fit, acclimatised trekker with a daypack.

Total walking comes to roughly 110 to 130 km with cumulative ascent well over 5,000 m. The Tilicho detour itself adds about four days to a standard circuit.

The Landslide Traverse: The Crux of This Trek

Between Khangsar and Tilicho Base Camp the trail crosses a long series of actively eroding scree slopes. This is the single most-discussed section of the route and the reason some trekkers skip Tilicho entirely.

What it actually is: a narrow path cut across steep, loose, sandy-grey slopes with a long runout below and no vegetation to hold anything in place. There is nothing technical about it — no exposure requiring hands, no ice in normal season — but the ground is genuinely unstable and stones come down from above.

How to handle it:

• Cross early. Rockfall increases as the day warms and as parties above you dislodge material. Leaving Khangsar by 7 am is the standard advice and it is good advice.
• Do not stop in the middle of a chute. Move steadily across the exposed sections and take breaks on the stable spurs between them.
• Spread out. Groups bunched together on a scree traverse knock stones onto each other. Leave gaps.
• Look up periodically. Trekkers coming the other way, and goats, both start rockfall.
• Avoid it in or straight after rain. Wet scree is worse in every respect, and monsoon is when the slope genuinely reshapes itself.
• An upper and a lower variant exist, and which one is in use changes with the state of the slope. Your guide should know which is currently the safer line — this is a real argument for a guide who has been here this season.

Most trekkers find it less frightening than the descriptions suggested. That is partly because they cross it early, in good weather, with someone who knows the line. Do all three and it is a memorable walk rather than an ordeal.

The Lake Day from Base Camp

From Tilicho Base Camp (4,150 m) to the lake is a climb of nearly 770 m on a relentless zig-zag up a scree and rubble slope, followed by a short traverse to the shore. Six to eight hours round trip for most parties.

• Start pre-dawn, typically 4 to 5 am. The wind on the lake basin rises sharply through the morning and by midday it can be genuinely unpleasant standing on the shore.
• It is a hard day for the altitude gained — 770 m up and back down, starting at 4,150 m, with no lodge or shelter above base camp. Carry water and food.
• Dress for a windy 4,919 m. The basin is a natural wind funnel. Down jacket, windproof shell, hat, gloves, and eye protection against blown grit as well as sun.
• The lake is frozen from roughly December to April, which changes the experience entirely: a vast white plate ringed by the Grande Barrière rather than the turquoise-and-steel water of autumn.
• You sleep back at base camp. There is no accommodation at the lake, and sleeping at 4,919 m after climbing to it would be poor acclimatisation practice anyway.

At around 4,919 m, Tilicho is one of the highest lakes of its size anywhere in the world, sitting beneath the wall known as the Grande Barrière on the north side of the Annapurna massif. The scale is what people remember — it is a genuinely large body of water in a place where nothing else lives.

Route Variants

Tilicho out-and-back, skipping Thorong La (9–11 days)

Walk in to the lake and return the way you came to Manang and out by jeep from Chame or Besisahar. Shorter, cheaper, and it removes the highest and most demanding day. A sensible choice if the lake is your objective and a 5,416 m pass is not.

Tilicho plus the full circuit (16–20 days)

The complete Annapurna Circuit with the Tilicho detour built in, walking the lower Marsyangdi stages rather than driving them, and continuing past Jomsom down the Kali Gandaki. The most complete version of this journey.

The Mesokanto La crossing (expedition-style)

From the lake it is possible to cross Mesokanto La (around 5,100 m, with variants) directly west to the Kali Gandaki valley near Jomsom, bypassing Thorong La. This is not a teahouse route: there is no lodging, it requires camping and a support crew, route-finding is serious and conditions vary hugely. Only attempt it with an operator who runs it regularly and knows the current state of the crossing.

Extra night at Tilicho Base Camp

Some trekkers add a second night at base camp, either as a weather buffer or to acclimatise before the lake day. Given that the traverse is best crossed once in each direction in good conditions, and that base camp lodges are limited, this is worth building in during peak season rather than hoping.

Skipping Tilicho on the circuit

Worth stating plainly: plenty of circuit trekkers skip Tilicho, and it is a reasonable decision. It adds four days, one exposed traverse and a very hard high day. If the group is struggling with altitude at Manang, going straight to Yak Kharka is the right call.

Key Landmarks on the Route

• Chame (2,670 m): Manang district headquarters and the practical start point now that the road reaches this far. Hot springs, shops, ACAP checkpoint.
• Paungda Danda: the enormous curved rock face above the trail beyond Chame, one of the circuit's landmarks.
• Upper Pisang (3,300 m): the upper of the two Pisang villages, worth choosing over Lower Pisang for the views and for starting the high route.
• Ghyaru (3,730 m) and Ngawal (3,660 m): Tibetan-influenced villages on the high route to Manang. Harder walking than the valley trail and much better both for views and acclimatisation.
• Manang (3,540 m): the hub of the upper valley — bakeries, gear shops, a Himalayan Rescue Association post that runs free altitude talks in season, and the last substantial supply point.
• Khangsar (3,734 m): the last permanent village on the Tilicho branch, and where the traverse begins.
• Tilicho Base Camp (4,150 m): a small cluster of lodges in an otherwise empty basin. Limited beds, cold, and the launch point for the lake.
• Tilicho Lake (4,919 m): the objective. Frozen roughly December to April, open turquoise-grey in autumn.
• Yak Kharka (4,050 m): grazing settlement where the Tilicho branch rejoins the circuit.
• Thorong Phedi (4,500 m) and High Camp (4,925 m): the two staging options below the pass. High Camp shortens the pass day but is a harder night's sleep.
• Thorong La (5,416 m): the circuit's high point, marked by prayer flags and a tea stall in season.
