Trek over Gosainkunda back to Kathmandu instead of driving. Gosainkund is a beautiful blue high-altitude lake. It is preferable to trek to Gosainkunda on the return from Langtang rather than on the way, as it requires a fairly steep ascent, and by this point you will be better acclimatized, making the height of the lake (4,380 m.) less of a concern. (If trekking this route without a guide, be especially careful with the altitude—numerous people have been caught out by a dangerous error in a commonly available trekking map that incorrectly lists some altitudes.

Accommodation & meals
The Langtang Valley had been very well set-up with plenty of comfortable lodges. The standard here is good, with warm blankets, fireplaces, comfortable beds, the occasional hot shower (for an extra fee) and a variety of food. Don’t forget to try the momos in this region, as they are larger and more pastry-like than those commonly found in the capital.
