Rightly termed as the trekker's heaven, this is one of the most adventurous trekking routes of Himachal Pradesh. The route starts from the heart of the beautiful village of Manikaran and is covered with colorful flowering plants and waterfalls as you start climbing. This grace and charm will then slowly give way to the rustic beauty in the form of rocky terrains and rough roads as you go higher up. You should carry a kit with you with all essentials including water and some light food. Also important is wearing is comfortable clothes and shoes.
