An endless variety of landscape, numerous villages of multi ethnic culture, from hot humid climate to cold tundra climate and simultaneous verity of vegetation is the speciality of eastern Nepal. The trekking to Makalu Base camp and Kanchanzanga base camp can really be challenging as it is one of the remote and unfrequented. Mt Everest, Kangchenjunga, Lhotse, and Makalu are the highlights of this region. Trekking in this region provides difficult & potentially very dangerous Passes like Sherpani & west Col into the upper Hongu Besi. Trekking through beautiful valleys of Barun and Arun can be an achievement of a life time.
