An excellent run in decent levels. The harder grade 4 drop is at the takeout, just below the bridge in Rhayader. Takeout after the drop on river right.
Takeout in Rhayader, just downstream of the B4518 bridge on river right after Rhayader Falls. Putin at Llangurig at the minor road bridge (turn off the A44 at the church).
Rainchasers is best experienced as an app.
