Malsi Deer Park / Dehradun Zoo is the only zoo in this city where you can spot deers and leopards with wide range of flora & fauna. Don't expect too much from this place if you love to see rare animals. This zoo has different areas like Aviary, Aquarium, Crocodile, Leopard & Adventure where you can start to walk from Aviary part and finish the round circle with Adventure. You can spend 1/2 - 1 hour easily walking around the premises but as I said, it's just a small zoo with nothing unique in it.
