The Helambu area, one of the most beautiful regions in the foothills of the Himalaya, is just a few days trek away from the city of Kathmandu, just over the Kathmandu Valley rim. It is situated directly northeast of Kathmandu in the Central Himalayan Region. It is in the Sindupalchowk district of the Langtang National Park. Helambu treks begin from Sundarijal or Melamchi Pul.
The people of the Helambu region are often referred to as ‘Sherpas’. However, neither their languages, customs nor clan structure resemble the Solu-Khumbu Sherpas of the Everest region. They are thought to be more akin to the Langtang Bhotias, and may also have originated from the Kyirong area of Tibet just across the border. Their religion and monasteries show their rich Buddhist culture. At lower elevations along the edges of the park, other middle hill tribes and castes reside, including Brahmins, Chhetris, Newars and some Gurungs.
