The vast, turquoise blue Siang runs through the heart of the valley it lends its name to, and is easily its showstopper. Nearly everywhere you go, you can see a sliver of greenish-blue hues gleaming in the distance. Rafting down the length of the river is a great way to get up close with the river and experience it. Aquaterra organises fixed departure rafting expeditions down the length of the Siang. Be sure to visit villages and experience homestays too and not just be restricted to campsites.
