More about O’Sullivan’s Cascade
Make the stairs part of the planO’Sullivan’s Cascade is a small, stepped waterfall in Tomies Wood above Lough Leane.
O’Sullivan’s Cascade is a small, stepped waterfall in Tomies Wood above Lough Leane. A signed spur leaves the woodland walk and drops about 130 steps to the falls, with another short descent to the lake edge. This is a walk-in stop, not a roadside pullout, and you climb back up the same steep steps. The stones can be slick, so if stairs or uneven ground are a problem, skip the spur and enjoy the woodland route instead.

The Tomies Wood loop has a lower and a higher route. The high section opens out over Lough Leane toward Killarney, Ross Castle, Tomies Mountain, Shehy and Purple Mountain. The cascade is the close-up stop; the upper path is where the landscape spreads out.
