The Ak-Suu region (Район Ак-Суу) is one of the best places in the country to launch yourself into the hills and mountains of the Tian Shan. With so many trekking opportunities and a concentration of well-informed travel agencies, there is no good reason not to. Using Karakol as a base, hike up to remote mountain lakes or down red-rock valleys with views out over Issyk-Köl far below.
