Ansoo Lake, Mountain lake in Kaghan Valley, Pakistan.
Ansoo Lake sits at approximately 4,200 meters altitude and has a distinctive teardrop shape with clear water surrounded by steep mountain slopes. The lake extends across several hundred meters and is fed by glaciers in the higher regions above.
Pakistan Air Force pilots discovered this hidden lake in 1993 during a low-altitude flight over the Kaghan Valley mountains. This discovery later brought attention to the site among trekking enthusiasts.
The name Ansoo comes from the Urdu word for teardrop, reflecting local legends about a prince whose tears formed the lake. The shape and story of the lake are known among hikers who visit this remote location.
Reaching the lake requires a multi-hour trek from Saif ul Malook Lake through mountain paths and is best attempted during warmer months. Hikers should start early and bring sturdy footwear and weatherproof clothing, as conditions can change rapidly at this elevation.
The lake reaches depths of around 36 meters and remains cool enough to swim in even during summer temperatures. Its remote location and extreme elevation make it a rare destination for adventurous hikers seeking something few others have seen.
