Dudipatsar Lake or Dudipat Lake is a lake encircled by snow clad peaks in Lulusar-Dudipatsar National Park. The lake lies in the extreme north of the Kaghan Valley, in the Mansehra District, Khyber Pakhtunkhwa province, in northern Pakistan. The word “dudi” means white, “pat” means mountains and “sar” means lake. This name has been given to the lake because of the white color of snow at surrounding peaks. In summer the water of the lake reflects like a mirror. The word “sar” is used with the name of each lake in the area, translating as ‘lake.’
