It is said that in the early days the local villagers of Kullu, Chamba or Kangra valley of Himachal Pradesh used a route to reach Barabangal through some high altitude passes in Dhauladha ridge. One of such passes is known as the Thamsa Pass (15,434ft), used by the local villagers to communicate with the NayaGaon or Barabangal. Solang Pass which is also known as Tentu Pass (4996m) is another option for the same but has a steep dangerous ascends from the Solang side. This pass is a divider of two sources of the river viz. Beas in Manali side and Irabati in Baranagal side. Now days it is rarely used by the trekkers to reach Barabangal because of the stiffness of the trail. TapanPandit with his team members Shiv Shankar Pal, KarunaPrashadMitra, UshaPandit and Anjan Das explored this unconventional trail in May, 2003.
