Wish to visit unpopular places??? Dalhousie- Chamera, less tourists. Kalatop jungle resort. Chamba- stay at orchard hut on hilltop away from the commercial town. Mashobra near Shimla.
Dharamsala, McLeodganj
These both are located like 5-10kms from each other, there's lot of untouched beauty out there you'll love it. From McLeodganj you can go for Triund Trek (Google It) I bet you, you've never been on something like that. so much of scenery and Adventure at one place. Camping under the stars.
