Ansoo Lake is a high altitude lake in the Kaghan Valley near the Malika Parbat mountain (Himalayan range). It can be reached by a difficult trek from the Saiful Mulook Lake. The name comes from its tear-like shape (the Urdu word "Ansoo" means teardrop). The lake is said to have been discovered in 1993 by Pakistan Air Force pilots who were flying low above the area. Earlier the lake was not even known to the locals.16490 feet above see level.
