A wonderfully serene spot, as the Slieve Bloom Way runs alongside the Barrow River. Ideal for putting the feet up for a breather.

The waterfall is not too far from the parking lot and is easy to include in a short hike.

From the parking lot you are directly in the forest and it is not far to the waterfall. It is possible to make tours of different lengths. The paths are well signposted.

In addition to a great waterfall, there are stone slabs right on the water at this point of the river where you can relax and cool your feet. The stone formations also look super interesting and make a great photo opportunity.
