Hi, Vaibhav! If you're currently in Kasol, you have to reach Jari by bus or a taxi. Once in Jari, you can start the trek to Malana which takes around 4 hours. From Malana, it is further 10-km trek through stunning rhododendron forests with incredible views of Parvati valley landscape.
Reach Jari ( a place 23 kms from Bhuntar). Best way to do this is to board a public bus which is going to Manikaran/Barshen (20-50 INR). From Jari hire a cab till Malana gate (400INR/person). Then, from Malana Gate you need reach a dam which is at a distance of 2 kms from the gate.
