Second stop- Himalayan zoological park (3 km from Gangtok)If you happen to be a person who likes to watch rare and wild animals while hiking through a park-cum-forest, then this is certainly the place for you. You can very easily spot snow leopard, red panda* (state animal of Sikkim), Himalayan bear, and civet cat inside the park which aren't typically seen in other parts of India.
6) Himalayan Zoological ParkOne of the best places I have ever been to. A zoo in between the hills. Here you can find some rare animals like Blue Goat, Snow Leopard, Red Panda etc etc. A must Visit place. But keep in mind you have to walk a lot through the elevation. There is also a bird sanctuary adjacent to it. Must Visit PlaceThe Entry Point to the Zoo...
