Three main trek routes; 1) Langtang Valley, 2) Helambu and 3) Gosaikunda Lake cover much of the Langtang National park and the southern Helambu region. Langtang and Helambu regions are connected through Lauribina La. All routes have the facilities of locally operated hotel/lodge, teahouse, and campgrounds for groups. The park offers a choice of moderate to more difficult hiking with duration ranging from 3 days to 3 weeks. Lodges operate year round except during the peak winter when the trails are blocked. Trekkers who take extra time to explore trailside wilderness (e.g. near Ghora Tabela and Kyanjin) hill top view point (Kyanjin), and cultural sites (notably in Langtang village and Melamchighyang. Tarkeghayang and Shemathang) will be well rewarded. One has to be self sustaining to venture remote areas of the Park such as Panch Pokhari (five lakes), east of Helambu, the toe of Langshisa glacier, and upper level valley from Kyanjin: and over the challenging Ganja La pass in upper Langtang Valley.
