Helambu is popular among the trekkers for its scenery and favorable climate. Located about 72 kilometers northeast of Kathmandu, it extends from north of Taramarang to the tree limit of the Gosainkunda Lake and lower slopes of Jugal Himal. There we meet several highland Tamang and Sherpa villages, scattered on both sides of the Malemchi Khola.

The Langtang valley is aptly called " the valley of glaciers". Here the mountain-scape is spectacular. On either side of valley, mountains rise, soaring into the sky. The valley offers pine forest, slow moving rivers and swift mountain streams, rugged rock and snow-capped peaks, grassy downs and meadows strewn with daisies and wild primulas. In the upper part of the valley there are snow bridges spanning angry torrents, high passes enveloped in mist, tiny lakes with icebergs floating on them and waters of crystalline brightness.

This trek is comparatively easier one due to the fact that the elevations are lower, ranging between 800m. and 3600m, offering less climbing as well as warmer temperatures. The most important benefit of this trek is that the area is less crowded & free from noise in comparison to the Annapurna trek and some parts of the Everest treks. Besides this, the trek offers a wide range of cultures and spectacular scenery.
