Let us mention the most reputed treks: the Dhaulagiri tour - Jomosom and Muktinath via the valley of the Kali Gandaki and the Annapurna tour, one of the world's most beautiful treks. Many itineraries also in the Khumbu region (leaving from Namche Bazar) - land of the Sherpas and mythic territory of the Everest. Finally, those who love "out of this world" hikes will have to go to Dolpo, in the west of Nepal. This old Tibetan kingdom is one of the world's highest inhabited regions. Beware, if you want to go to Dolpo, you must apply for a trekking permit and necessarily require the services of an agency.
