Photo: GetYourGuideStrap in for one of Nepals longest and highest ziplines, screaming down a forested ridge near Dhulikhel with the Himalaya as a backdrop on clear days. The half-day adventure includes hotel pickup and lunch, making it an easy adrenaline hit from the city. It is well run with modern safety gear and thorough briefings. Wear closed shoes and secure any loose items, and go in the morning when winds are calm and mountain visibility is usually at its best.
