Apart from playing an important role in Hindu mythology, Sheshnag Lake is also known for being home to various types of fish. Many people are seen fishing in the lake for brown trouts and more. Since the environment of the area gets colder and gets covered with snow during winters, the most suitable time to visit the Sheshnag Lake would be between June - September. Tourists will be able to view slight snow on the mountains which are visible from the lake and will be able to view pleasant yet dense forest covering the lake.
During winters, the Sheshnag Lake gets covered by snow and a layer of ice forms on the whole lake. This type of weather is suitable for people who love snow and want to visit cold places. Trekking and camping programs are also organized near the Sheshnag Lake which leads to Amarnath cave which is located near the Sheshnag Lake.
