The climb down to Nagdah is an extremely steep one: allow for much more time on your way back. After Nagdah, the trail leisurely follows the Tama Koshi through pine forests. Stay overnight at Singati (1 hour).

The trail follows the Sangewati Khola on the left side for about three hours until you reach a place called Sunung Khoh. A teashop serves 'dhal-bhat' on order here. Then comes a steep climb up to Chagu and again down to the river at Sangbe where there is a newly built suspension bridge. A less than average trekker should stay overnight either at Chagu or Sangba and attack the steep trek up to Bigu (2 hours) on the following morning.

Food and shelter are available at Sangba or infamnaly, with some of the richer people at Chagu

You can return to Charikot via Tinsang La (3319 m) and the Kalinchowk range (3,810 m). This can be done with a very early start from the Bigu monastery and if you are a very fast trekker, in one day, but it is more likely to take you a day and a half. You can reach Tinsang La in three hours and, if the shepherds are there, find very "down-to-earth" accomodation with them. On top of Kalinchowk and a little below on the other side are houses where accomodation is avaliable. The second hour is inhabited by a Yogi who accepts guests around his fireplace. In early spring watch out for snow. In the spring you might run into a hail storm on the top of the mountain, a rather unpleasant experience. This route is, however, a most beautiful and exciting one, especially in autumn when birds and wildlife abound.

You will need a guide here as the trails are numerous and ill-defined. Water sources are scarce and little known. Avoid returning by the area around Tarebhir as this is a most tiresome and difficult trail and the area is extremely poor in food crops.

An alternative to the Kalinchowk route is to go down from Tinsang La to Barhabise (5 hours) along the old trekking route on the ridge above the Sun Kosi valley. After a long day's walk you are compensated for your labours by all the blessings of electricity; light without smoke, cool drinks and comfortable lodges.
