Himachal Pradesh is paradise for trekking freaks and offers a virtual bonanza for them. April-May for low altitude trekking & camping & June to October is season for treks (moderate to strenuous). The land of many facets. Himachal lies to the south of Jammu and Kashmir State. The lush green valleys of Kullu & Manali are populated by the descendants of Hindu Aryans, while the high arid desert plateau of Lahaul and Spiti is a stronghold of the Buddhist religion, and is similar to Ladakh and Zanskar, in landscape as well as culture. Not much of the fascinating area has been explored yet, and the valleys of the Dhauladhar range, populated by the Gaddis or the nomadic shepherds of this region hold mysteries in their lap for you to unveil. Paradise for trekkers. Every grade of treks are available. Glacier line ( Permanent snow line) is much closer in Himachal than any where else in Himalayas.
