I have visited only Mussoorie. I would like to visit more in future. Shimla, Manali, Darjeeling, Ooty, Nainital, Coorg, Kodaikanal,etc, etc almost all. I'm also keen on visiting Buddhist monasteries high in the Himalayas for solitude. I think people should visit the hills more often for solitude and spiritually rather than the beaches for party and liquor.
