Due to rare bird species being present in the forest surrounding the Thol Lake, the area was declared as the Thol Lake Bird Sanctuary in the year 1988. Since many migratory birds also used to visit the lake the area for the sanctuary kept increasing over the years while protecting other animals present in the surroundings. Later the Thol Bird sanctuary was converted into Thol Wildlife Sanctuary where the flora and fauna of the wildlife were being protected by the state government.
According to the Environment (Protection) act 1986, the Thol Lake Bird Sanctuary was declared as an Eco-sensitive Zone. There is a resort located beside the Bird sanctuary which provides tourists with a peaceful environment while enjoying nature. This Bird sanctuary is very famous amongst tourists and thrill-seekers as various camping and trekking programs are also organized throughout the year but the best season to visit the Thol Bird Sanctuary would be between November to February ideally.
