Langtang area is toward the north of Kathmandu Valley. The scenery here is spectacular, and the trek more adventures as the area is visited by fewer tourists. To the west of Langtang is Ganesh Himal with a range of 6000 to 7000 meters. The main ethnic groups living here are Sherpas and Tamangs. The forests in the region have temperate and sub-alpine vegetation. Wildlife including migratory birds, dear, monkeys, Tahr and Pika. The best time for trekking in the Langtang area is spring and autumn. Most of the trekking routes in Helambu and Langtang are well served with tea house making independent trekking quite possible. But, there are no such facilities in the Ganesh Himal area or Ganja La area.

The northern parts of the area largely fall within the boundaries of Langtang National park. Entry permits should be obtained from Thamel, Kathmandu, before starting the trek. To reach Helambu from Kathmandu a permit to pass through Shivapuri watershed Area is required. This can be obtained at the entry permits counter at the National Park.
