Geographically, it is a land of dramatic contrast.
Trekking around the giant Himalayan Peak Dhawalagiri (8th highest Himalayan Peaks of the world) is one of the most challenging trekks.
The trek goes through big challenging mountain passes, crossing over French pass (5360 meter) and Thapa Pass (5200 meter); It is a challenging walk on an icy track.
The river Kaligandaki is named after goddess Kali, it rises in Mustang, an enclave of Nepal poking in to Tibet on the northern side of the Himalayan range.
It flows between the high Himalayas Dhawalagiri and Annapurna creating the world's deepest gorge and then into an arid open valley.
Rafting this river, riding through technical rapids, challenging the medium and lower flows is lots of fun.
