The Lower Chamkar Chhu gorge is one of the most beautiful canyons in Bhutan. It’s nestled in a deep forested canyon South of Jakar in the Bumthang Valley. You can start anywhere downstream of Jakar where the road is close to the river. After a mile or two warm up the road leaves the river and the canyon starts to gorge up. Boat-scoutable Class III rapids come on after another for the next few miles.
The take-out for this run is the tricky part. There is a small eddy behind a rock on the left side that you must catch to reach the take-out trail. Below here the river gets much more difficult with little access. It’s a steep 10-15 minute walk up the canyon to reach a parking area in a pine forest.
Mile 0: Put-in at the bridge in Jakar. There are a few other places to access the river below here if you’re looking for a shorter warm-up.
Mile ??: There is a tricky Class III rapid that can be scouted from the left.
Mile ??: Take-out behind a rock on river left. You don't want to miss this eddy since the rapids below are much more difficult and there is no river access.
