Pontsarn Blue Pool

Highlight • Natural

Blue Pool.
At the bridge, head downstream on the right bank, following the path, to reach the Pontsarn Blue Pool. The path can be followed as far as desired beyond here, through the nature reserve. After some distance, there are a couple of paths leading up to the Taff Trail (such as one just before a weir in the river, 2 km downstream of the waterfall), which runs along the remains of a dismantled railway line.

The Taff Trail can be followed to the right, eventually crossing over the impressive Pontsarn Viaduct. 350 metres beyond there, a path on the left drops down to a footbridge over the river. On the other side, a path beside the river can be followed to the left, passing under the viaduct again, all the way back to the start of the walk.
