The country's diverse terrain is what mountain bikers' dreams are made of. Biking offers an environmentally sound way of exploring the country. Riders can explore rims and ridges of Kathmandu valley and Pokhara through off routes that weave in and out of the cities. Centuries-old roads and trails offer a chance to go on extended trips to exotic locals like Annapurna and Kanchenjunga areas. Normally 21-27-gear bicycle are recommended when riding through tough terrain. Mountain bikes are available in Kathmandu or Pokhara for rent by day or longer.
