The Ala-Kul trek is the most popular multi-day route from Karakol, and for good reason: it combines dramatic scenery, manageable logistics, and a genuine high-mountain experience within a two or three-day walk of town. The route heads up the Karakol Gorge through dense spruce forest, climbing past waterfalls and alpine meadows before reaching the Ala-Kul lake at 3,532 metres — a startling turquoise pool hemmed in by grey cliff faces and glaciers.
The standard circuit crosses the Ala-Kul pass (3,860m) before descending into the Altyn-Arashan valley and returning to Karakol via the hot springs at Altyn-Arashan — a natural hot-spring settlement where a soak in the outdoor baths after three days of walking is one of the finer experiences the country has to offer. The full loop takes two to three days depending on pace. Yurt camps along the route provide accommodation and simple meals in summer; a tent is advisable outside peak season. Most guesthouses in Karakol can arrange guides, horses for luggage, and transport to the trailhead.
