The Bhutanese word for river is "chhu," so the Paro Chhu is translated to the Paro River. The Paro Chhu starts on the South side of the 24,035 ft Mount Jomolhari flowing through mountain meadows and deep gorges before entering the Paro Valley and meandering through the town of Paro. Just downstream of Paro is a fun Class III+ section of whitewater with one portage.

The road from Paro to Thimphu follows the river and there are several places to put-in downstream of Paro. The first few miles have great warm-up rapids before the Boulder Choke (V) which normally scouted and portaged on the right. Below Boulder Choke the scenery and rapids are the best on the run. The take-out is just before the confluence with the Thimphu Chhu at the small village of Chhuzom.

Trip Highlights

Mile 0: There are several places to put-in, but the most common is just upstream of a bridge where the road from Paro to Thimphu switches from river left to river right.

Mile 0.5: Wallbanger (III+) is a rapid you can see from the road and worth scouting from the road. The river takes a turn to the right after slamming into a wall on the left bank.

If you bring proper clothes and a Bhutanese guide you can also hike up and visit the Tachong Lhakang (monastery) established by the famous iron bridge builder Thangtong Gyalpo.

Mile 2.9: A driving bridge crosses the river here offering alternate river access before Boulder Choke (V).

Mile 3.8: Boulder Choke (V) is a long complex rapid with a lot potential to pin a kayak or raft. The entrance swiftly leads into the rapid so you should know where to pull over to scout/portage ahead of time.

Downstream of the portage the canyon is beautiful and the rapids come in quick succession. This is a really fun section of Class III+ rapids that ends just before Chuzzom.
