Drive from Mongar to Trashigang

The road from Mongar climbs past fields, to Kilikhar with its Buddhist college (shedra) and then through blue pine forests. Soon the road begins the climb clinging to the side of the cliffs and passing through deep forests of mainly rhododendron trees, up to Kori la pass (2400m) with mani (prayer) walls and prayer flags. From Korila pass, the road descends, switch backing down through broadleaf forests to the village of Naktshang. Continue descent through corn and mustard fields to arrive after one hour from the pass to a large village of Yadi (1480m). From here, the meandering road (Yadi loops) drops to Sherichhu valley, then meet Drangme Chhu river and the roads winds in and out of the side valleys to Thungdari (71km from Mongar or 20km from Trashigang). A side road leads to Drametse (18km of dirt road takes around 1hour each way). The road from Thungdari continues along the side valleys of Drangme Chhu river to Chazam (literally meaning iron bridge, named after chain bridge, built in 15 century, which stood here once). Chazam is the junction for road to Gomkora and beyond to Tashiyangste. From Chazam, the road climbs up for about 20minutes to Trashingang.
