A classic waterfall run. Two of the major drops are often portaged. The first is runnable with care (shallow landing), the second looks filthy - good luck! The rest of the run is excellent grade 4 before mellowing in the last km to easier water.
Takeout at the small bridge in Pontneddfechan, at the start of the "waterfall walk". To reach the putin head up the small road on river left before heading down a steep hill to the riverside picnic site at Pont Melin-Fach.
Rainchasers is best experienced as an app.
