Dhaulagiri, in central Nepal, is the world's eighth highest peak and along with Annapurna I, stands as a sentinel over the Kali Gandaki River, which forms the deepest river valley on earth. This challenging trek takes you to spectacular wilderness areas as we travel around the entire Dhaulagiri massif and along valleys that are little-travelled by locals, let alone by trekkers. The contrast of cultures, landscapes and outstanding mountain views as we circle this vast mountain provides the attributes that make this one of the best extended treks in Nepal. The ascent of Thapa peak (6012m) will be the highlight of this trek.
