Auli is a mesmerising spot to visit in winter. Though winter drops to minus, still there is lot of magic in winter snow. As you drive, so mesmerising nature of auli winter follows you. You could try winter views of snow capped hills- Mana parvat, Trishul, dunagiri and Nanda Devi..Trekking is so popular here, you shouldn't miss on skiing too. Visiting Pandukeshwar, neelkanth, Lord badri temple reminds you it's a devbhoomi, while you should try Asia's longest gondola ride. Manali is a popular tourist spot to peep in winter. playing and making snowmen, views of Beas kund,Bhrigu lake, wildanimals at the sanctuary are some spots to visit. Trek at chandrakhani pass, hampta pass are some must things to do besides visiting Mall road, Manu temple, old Manali and vashist kund. Since both are popular winter spots, I would suggest Auli.
