Trekking around the central Himalaya in respect of its cultural diversity and topographical variations is more exciting and interesting, exploring different culture of various ethnic groups, the lower ridges are inhabited by Tamangs and Sherpas whereas the higher region by Nepali Tibetans. This trek also provides a chance to observe one of a holy site of Hindu people, the sacred Gosaikunda Lake.

Straight north from Kathmandu is the Langtang region which enjoys snow covered peaks, a mild climate, and friendly hospitable inhabitants which makes it the ideal trek almost year round. The 1,710 SQ km Langtang National Park hosts a variety of natural splendours, from lush valleys alive with languor monkeys to the towering fir and rhododendron forests bursting with spring colour. The 7,246 meter Langtang Lirung to the north, Gang Chhenpo (6,388 meters) to the south and Dorje Lhakpa (6,975 meters) to the east dominates the beautiful Langtang valley. Helambu, the mid elevation region to the Park's south, is a study centre of Tibetan Buddhism. Lama and Tamang people maintain a rich cultural heritage, evident in ornately carved wooden windows, lively dance festivals, and skilled weaving traditions. Trekkers can enjoy these sights on any of the three main trekking routes. Hiking times and overnight stops are planned for a moderate hiking pace, and proper acclimatization to altitude. Treks range in difficulty from moderate to challenging. All trail heads are accessible by bus or private transports from Kathmandu.
