The region north of Kathmandu offers a multitude of trekking destinations, all accessible without flights. The major areas are Langtang, Gosainkund and Helambu, which can be combined in many different ways to make treks lasting from seven to 16 days. Langtang treks offer an experience not found elsewhere. The Langtang valley provides opportunities to relax into local settlements and to study flora and fauna along the way.
