Approach by Car: Park at Rhyd Ddu Car park. Approach by foot: Follow the signs to the ranger path (head NNW), the track stays away from the road and heads up hill crossing the railway line and through a slate quarry, when the track leads you to the footbridge over the river, you get in. Canyon entry: Enter by jumping, sliding or down climbing into the first pool (check depth first). Canyon descent: A progressive descent which starts off with small slides and abseils and progresses to more committing sections throughout. Refer to Topo. Exit: when you reach the footbridge, exit the canyon and head back to the car. Escapes: escape is possible in the upper section, would be much harder in the lower section.
