Clamp Hole Waterfall is a striking three-tiered waterfall on the River Barrow in Glenbarrow, County Laois, nestled within the Slieve Bloom Mountains.

The falls cascade over moss-covered rocks through a natural woodland gorge, making them one of the standout features of the Glenbarrow Waterfall Loop trail.

The waterfall is reached by following the riverbank path from the Glenbarrow trailhead, passing through bluebells in spring and crossing wooden footbridges along the way.

Walkers on the shorter green loop typically turn back at the falls, while those on longer routes continue upriver along the Slieve Bloom Way.
