The most baffling thing about the Hampta Pass trek, which sets it apart from the plethora of treks in the Himalayas is neither its remote location nor the challenges it offers but the absolutely contrasting vistas presented by the lush green Kullu valley and the rugged and dry Spiti valley. The high mountain pass acts as a gateway to an entirely different world, very few treks offer this dramatic transition. I shall now delve into the details of this trek objectively, before telling my own experience.
For your reference here is a map for the entire trek route assuming you will return via the Rohtang Pass to Manali.
Location:
The popular approach is from Hampta dam which is located at a distance of about 12km from Manali in Himachal Pradesh. From there the trek starts and after crossing the pass ends at Chhatru /Chatru, a small village on the Gramfu-Batal-Kaza road. The trek can also be done the other way round.For your reference here is a map for the entire trek route assuming you will return via the Rohtang Pass to Manali.
Season:
Try avoiding the monsoon at all costs. October - early November is definitely the best season. The roadway remains closed due to heavy snow accumulation till mid-August.
A note of caution: The travel agencies will tell you anything to keep their business running all year long, but do not make the mistake of taking any trek lightly irrespective of the tags like 'easy', 'moderate'. Depending upon factors like weather, River level which are beyond human control, a so-called easy hike in the Himalayas may seem to be an insurmountable obstacle.
