9. Khangchendzonga National Park
This is located in Sikkim and gets its name from the mountain Kanchenjunga, the third largest peak in the world. This park is full of glaciers and one can spot animals like musk deer, snow leopard and Himalayan Tahr. About 550 species of birds can be spotted in this park, but sadly, you need a permit to visit. The best time to visit is from March to May.
