The Rolwaling Valley trek, in the Gaurishankar Conservation Area (GCA) is a moderately difficult teahouse trek located in between Langtang National Park and Khumbu (Mt.Everest) in Nepal. It forms part of The Great Himalaya Trail.
The Rolwaling Valley trek is a relatively quiet trekking route that runs parallel to Tibet. The Sherpa village of Beding (3 days walk from Gonghar Khola) is the largest settlement in the Rolwaling Valley.
It is possible to combine this trek with Everest crossing Tashi Lapcha La (5755m), however, you will need climbing experience and guides to achieve this and another set of permits.
Tsho Rolpa (4580m) is one of the largest glacial lakes in Nepal. This is the point of turnaround if returning to Gonghar Khola.
Direct buses leave Kathmandu to ChhetChhet, Dolakha from the old bus park in the centre of the city (next to Ratna Park). This is conveniently located next to the Nepal Tourist Board where you can purchase your trekking permit. Two buses leave, at 6am and 8am, but double check times and consider reserving seats the day before. Price NPR 650.
The beginning of the trek is ChhetChhet Bazaar. The journey takes approximately 8 - 10 hours on a rough road.
Alternatively, you can take a bus to Charikot (NPR 330) and then catch another one to Lamabagar and get off at Chhetchhet.
Trekking permit costs 2000rs. If doing this trek in winter, likely that permit will not be checked (except possibly if you walk past the small office just before the bridge in Singati). February 2017, permit not checked.
TIMS not required.
Download maps.me app. Very useful to calculate distance, and many walking trails are accurately mapped. Useful if the trail splits and you don't have a guide or a helpful local nearby.
Standard mountain diet. Dal Bhat, fried rice, noodles. No fixed menus like Annapurna etc, which makes prices much cheaper at around 300rs for Dal Baht all the way up (February 2017).
Bowl of instant noodles around 100rs.
Black tea 30 - 50 rs.
You won't come across many shops once you leave the road so bring adequate supplies with you.
Don't forget water purification tablets/iodine etc.

This teahouse is also closed during the winter.
