Kooh Lake in Anakar Kalam Valley
Perched amid high mountains, Kooh Lake ─ a 'colour-changing' glacial lake in Anakar, Kalam valley ─ stands out from the 50 other such lakes spread over the alpine zone of Swat valley.
The lake, popular for its pristine water, is located 10,800 feet above sea level and can be reached after a seven- to eight-hour-long trek that guides visitors through a beautiful, lush-green valley.
It has nonetheless become a wildly popular attraction for local tourists and adventure seekers.
