Ala-Kul Trek in 3 Days: Stage by Stage

Ala-Kul is the trek most visitors to Karakol come for: a turquoise lake at 3,532 m, a high pass at 3,860 m, and a finish at the Altyn Arashan hot springs. The usual direction is a loop: up the Karakol Gorge, over the pass and down to Altyn Arashan.

Transport at either end is on Ala-Kul trek transfer and getting back after the trek.

This is a practical stage-by-stage guide. Times are typical walking times for a fit hiker with a full pack. Slower walkers should add an hour or two per day.

The route at a glance

Total distance is about 40–50 km. Stage times follow the classic itinerary published by central-asia.live.

Before you start

Season. July to September. June can work, but expect snow on the pass. In May the lake is usually frozen.

Fees. Expect a national park registration fee at the Karakol Gorge entrance (central-asia.live gives about 300 som) and a vehicle eco-fee if you drive in. In 2025 a Russian-language report gave about 500 som per car. Carry cash.

Water. Streams are frequent, but treat or boil everything.

Signal. Patchy at best. Assume no mobile coverage from the first day.

Acclimatisation. You sleep at about 2,900 m the first night and at 3,532 m the second. Spend a day or two in Karakol or do a day trip to Altyn Arashan first. Headaches and poor sleep at the lake are common.

Day 1: Karakol Gorge to Sirota

Getting to the trailhead. A taxi from Karakol to the Karakol Gorge trailhead costs about 1,500–2,000 som one way according to central-asia.live. Some hikers use the alpine camp road further in.

The walk. A long, gentle-to-moderate climb along the river through spruce forest. The path is wide and easy to follow. You gain about 1,100 m over the day.

Overnight. The Sirota area at about 2,900 m has a popular camp with mountain views. Water is nearby.

Tip. Go slowly. Day 1 is long, and pushing hard here makes Day 2 at altitude harder.

Day 2: Sirota to Ala-Kul lake

The walk. The path leaves the forest and climbs steeply over rocky ground and past a waterfall to the lake basin. Expect roughly 960 m of gain. A Russian-language 2025 report gave about 6.8 km and around four hours from the alpine camp area to the lake.

Overnight. Camping by the lake at 3,532 m. It is cold, often windy, and frost is normal even in August. A good sleeping bag and a stove are essential.

Tip. Arrive by early afternoon. Weather at the lake usually turns after midday.

Day 3: over the pass to Altyn Arashan

The walk. Follow the lake shore, then climb steeply on scree to the Ala-Kul pass at 3,860 m. On a clear day the view back over the lake is the highlight of the trip. The descent to Altyn Arashan is long and steep at first, then eases into meadows. About 630 m net loss over the day and four to five hours in total.

Overnight. Altyn Arashan has guesthouses, yurt camps and camping spots, plus hot pools at 35–41 °C. After three days on the trail, the soak is the reward. See where to stay in Altyn Arashan.

Tip. Start early to cross the pass before clouds build. Turn back if visibility is poor on the scree.

Day 4: getting back to Karakol

From Altyn Arashan, the jeep road runs about 12–17 km down to Ak-Suu village. On foot that is three to four hours on a rough track, then a minibus or taxi back to Karakol. Our Ak-Suu marshrutka guide explains the minibus.

Or skip the walk-out: a one-way seat in the shared 4x4 leaves the valley at 16:00 and reaches Karakol around 18:00. It costs 2,750 som. Book it before you set off: there is no signal in the valley.

Reverse direction: start at Altyn Arashan

Some hikers prefer to start with the 4x4 and do the trek backwards:

1. Day 1. One-way seat from Karakol at 08:00 to Altyn Arashan for 2,750 som. Arrive around 10:30. Rest, soak, acclimatise.
2. Day 2. Altyn Arashan → pass → Ala-Kul. The climb is long and steep from this side, so start early.
3. Day 3. Ala-Kul → Sirota → Karakol Gorge trailhead.

Advantages: you skip the long valley approach, sleep at 2,500–2,600 m first, and get the hot springs before the hard part. Pickup at the Karakol Gorge end is possible on request via WhatsApp. We confirm availability and price for that leg individually.

More on both directions on our Ala-Kul transfer page.

Two-day option

Fast hikers sometimes go up the Karakol Gorge to the lake in one long day (7–8 hours) and come back the same way the next day. This skips the pass and Altyn Arashan entirely. It is shorter but you miss the hot springs.

Packing essentials

• tent, sleeping bag rated to around freezing or lower, mat, stove;
• waterproof jacket and warm layers;
• boots with good grip for scree;
• water filter or tablets;
• map or offline navigation app;
• cash in som for fees, guesthouse and the jeep if you pay on the spot.
