3. Mustang, Nepal
Mountain biking in the Himalayan foothills may sound intimidating, and it certainly is! This is an area for experienced mountain bikers who love gorgeous scenery and local culture. One of the best trails is called Lo Manthang, which leads into the royal city of Mustang. Most bikers start their journey near Annapurna or at the nearby airports in Jomsom or Kathmandu. Keep in mind that biking the Upper Mustang requires a $500 permit, which is valid for 10 days.
