Issyk Kul is the largest lake in Kyrgyzstan and the second-largest saltwater lake in the world, after the Caspian Lake. The name of the lake means "Warm Lake" because even when the tops of the mountains that surround it are covered with snow, its surface does not freeze. Issyk Kul is the seventh deepest in the world, with a maximum depth of 668 meters. The beautiful blue water attracts tourists from the region, especially from Kazakhstan. Visitors from Western countries, in addition to swimming, often go trekking in the surrounding mountains.
