About Big Almaty Lake

Big Almaty Lake sits high in the Trans-Ili Alatau above the city, a turquoise reservoir held behind a dam with peaks rising straight from its shore. The drive up passes the Medeu rink and the Shymbulak ski resort, and walks along the ridge give wide views back over Almaty. Access is sometimes limited by landslides or snow, so it is worth checking locally before setting out. June to September is easiest; October brings golden larch, and winter closes parts of the road.
