Hi Kavi, Nainital offers beautiful views of the mountains and the famous Naini Lake but lately its been crowded with people flocking from all over the nation. But just a few miles away from Nainital lies a tiny hamlet called Pangot which is absolutely secluded with virgin forests and chirps of over 300 species of birds. I recommend you explore Pangot, if possible, you won't be disappointed. Here's my experience from when I visited Pangot: https://www.tripoto.com/pangot/trips/pangot-an-ideal-weekend-getaway-to-a-paradise-lost-in-time-606092219d71b
Hope it helps!
