Langtang Region offers a multitude of trekking destinations, all accessible without flight. The major areas are Langtang, Gosainkunda Lake (Frozen Lake) and Helambu, which can be combined in many different ways to make treks lasting from 5 to 16 days. Langtang treks offer an experience not found elsewhere. The trail is challenging with long, step climbs and descends, often through deep forests or across glacial moraines. There are outstanding close-up mountain views and interesting villages with well-established lodges.

Just north of Kathmandu are two lovely where one may experience Tamang and Sherpa life, temperate forest and alpine pastures, glaciers, lakes and snowy peaks. Helambu valley noted for its scenic grandeur and pleasant climate is just north of the Kathmandu Valley. One can stay in highland monastery villages and small settlements in pristine forests. Above Helambu is a mountain pass the lake of Gosainkunda to the valley of Langtang. Gosainkunda Lake itself is situated at 4,380 meters. It is sacred to Lord Shiva and every summer is the scene of an important pilgrimage. Nearby are other lakes including Nagkunda, Bhairavkunda, Saraswatikunda and Suryakunda. The trek passes through a varied landscape ranging from evergreen forests, cascading waterfalls and turbulent streams to sub-alpine grasslands and stark, beautiful mountainsides.

Langtang Valley stretches north of Gosainkunda. One travels through pristine forests to the village of Langtang, then the valley opens out into a high, Himalayan river plain full of beautiful camping sites, spectacular peaks and wide glaciers. One can hike to the back of the valley or take numerous optional trips to explore glacier-filled side canyons.
