Forest trail along the Karrika River. The trail passes through a small tunnel near Bidaita. The forested landscape is the perfect setting for any good hike.

This wonder of nature is one of the numerous geoforms that you can find in the Valley of Colors. To get there you will have to deviate a little from the trail, but it is worth it.
