The lake is surrounded by lush greenery and the weather is conducive for trekkers and nature enthusiasts who wish to enjoy the scenic beauty without the hindrance of heavy rains that dominate the monsoon season. Furthermore, as this is also the migratory period for various bird species, bird watchers get an exclusive opportunity to observe a plethora of avian life in its natural habitat.
Visitors should particularly consider planning their visit between November and February, when the temperatures range from a comfortable 11°C to 24°C. During these months, the lake's environment remains serene, and one can indulge in boating or picturesque walks around the area. It's important to note that while the days are generally warm and sunny, nights can become quite chilly, so travelers should come prepared with appropriate clothing.
