**The Ala-Kul trek is Kyrgyzstan’s most popular multi-day hike: about 50 km in 3–4 days from the Karakol valley up to the turquoise Ala-Kul lake (≈3,550 m), over a pass of roughly 3,860–3,900 m and down to the hot springs of Altyn-Arashan.** It starts 10 km from the town of Karakol, the season is July to mid-September, and guided tours cost roughly $250–550 per person (as of 2026).

## Ala-Kul trek route by day

| Day | Section | Distance / time | Altitude gain | Overnight |
|---|---|---|---|---|
| 1 | Karakol valley gate → Sirota camp | ≈15 km / 5–6 h | +800 m (gradual) | Tent or hut |
| 2 | Sirota → Ala-Kul lake | ≈6 km / 4–5 h | +1,000 m (steep) | Tent at the lake |
| 3 | Ala-Kul → pass ≈3,900 m → Altyn-Arashan | ≈15 km / 7–8 h | +350 m / −1,300 m | Guesthouse with hot springs |
| 4 | Altyn-Arashan → Ak-Suu | ≈14 km / 4–5 h walk or 1.5 h 4x4 | −1,000 m | Karakol |

Fit hikers sometimes do it in 3 days by combining days 1 and 2 (a very long day) or by driving to the second bridge in the Karakol valley. You can also walk it in reverse from Altyn-Arashan, which makes the climb to the pass more gradual.

## How difficult is the Ala-Kul trek?

Moderate to hard. The first day is easy forest walking along the river. Day 2 is a steep climb next to a waterfall, gaining about 1,000 m in a few kilometres. Day 3 crosses the Ala-Kul pass on loose scree; there may be snow patches even in August, and the weather changes fast. Altitude is the main risk: anyone arriving straight from Bishkek or Almaty should spend a day in Karakol first. You do not need technical skills, but you do need proper boots, poles and experience of mountain hiking.

## How much does the trek cost?

| Item | Price (as of 2026) |

| Guide / porter | ≈$40–80 per day each |
| Guided 3–4 day tour, all-in | ≈$250–550 pp |

## Self-guided or with a guide?

The trail is well used and marked in places, and many hikers do it on their own in July–August using offline maps. Go with a guide if you have little high-mountain experience, are hiking alone, are travelling in September when snow is more likely, or simply want tents and food carried. Karakol has rental shops and trekking agencies; most now take bookings online and accept card or QR payments. Register your plan with your guesthouse and carry a charged power bank — mobile coverage is very limited above Sirota.

> **Myth:** “Ala-Kul is an easy day hike from Karakol.” **Fact:** the lake is at ≈3,550 m with a 1,000 m climb on the second day; one-day 4x4 + hike “express” options exist but make for a 10+ hour day.

## What to pack

- Tent and a sleeping bag rated to −5 °C (nights at the lake are near freezing).

- Waterproof jacket, warm layers, hat and gloves.

- Trekking poles for the scree descent; sunglasses and high-SPF sunscreen.

- Water filter or tablets; stove and food for 2–3 days.

- Cash in som for park fees, huts and guesthouses.
