These regions are the most convenient to Kathmandu. Just above Kathmandu is Helambu and the basic trek through the Helambu region makes a circuit from Pati Bhanjyang. Trekkers can begin their trek to Gosaikunda and Langtang, beginning at Syabrubesi in Rasuwa to the northwest of Kathmandu and via routes linking them with Helambu.

Langtang, Gosaikunda and the northern part of Helambu come under the territory of Langtang National Park with headquarters at Dhunche.
