The Manaslu Circuit Trekking is about 177 kilometers long. In the past, there was no road access to the Manaslu region or the Annapurna Circuit (from Dharapani to Besisahar). Therefore, the only way to do the Manaslu Circuit was to trek the entire circuit. This is known as the Classical Manaslu Circuit, which takes 17 days to complete, starting in Arughat and ending in Besisahar. Today, there are several different customized Manaslu Circuit itineraries available, ranging from 12 to 20 days. The 12-day and 14-day itineraries are for the Short Manaslu Circuit Trek, while the 20-day itinerary is for the Manaslu Circuit and Tsum Valley Trekking.
