The Langtang trek can be done in as little as a week. After a days walk the trek gets really interesting, first following the continuation of the Dhunche road up the unpromising valley of the Bhote Koshi before leaving the road moving towards Syabru in the Langtang Valley. You climb up the gorge like lower valley, where oaks and rhododendron give way to peaceful hemlock and larch forest; after ascending an old moraine, snowy peaks suddenly loom ahead and the gorge opens into a U-shaped glacial valley. The Langtang village is good place to spend a night, while Kyangjin boasts a small gompa and a cheese factory. The Langtang Glacier is a full day’s walk further up the valley. You can move more ahead and reach Tsergo, from here you can view and awesome white wilderness of peaks.
