Hi! Himachal would be your perfect go-to if you want to enjoy snow-capped mountains and serene valleys, and is nearest from Delhi. You could travel to Manali, Shimla and/or other higher peaks. Most of these are accessible via Volvo buses running from ISBT/Mandi House/Majnu ka Tila and take 9-10 hours on average. Tip - Travel through the night to save time and you would wake up in the hills by the time its morning!
