Old Manali and McLeod Ganj were my fave places. My friends used to tell me (rave about) other places in the Himalayas that were very remote, but I never found time to go there.
Nor did I get to the NorthEast .. Assam, Nagaland, etc. I really would have loved to get there, and had even made some plans which fell through. Then I left India.
Maybe someday ...
Oh I've been there, they're beautiful places. I can't wait to go back home again until later this year. I haven't been to the Northeast either though, I do wish to visit Nepal too. Hopefully, someday we all get to be where we want to be :D
