A beautiful waterfall, a little hidden :-)

The hike to O'Sullivan's Cascade feels like a little journey into another time. Hidden deep in Tomies Wood, the waterfall flows down several steps into the green depths. The path there leads through dense oak forest, which immediately captivates you. As soon as you have taken the first steps, you are surrounded by the calming sound of water and the rustling of leaves - an almost magical atmosphere. What I particularly liked: O'Sullivan's Cascade is often quieter and less crowded than the famous Torc waterfall. It is even said that whisky once cascaded down the rocks, or so the legend goes. But today it is pure, crystal-clear water that makes its way through the moss, creating small rainbows in the spray. Plan a short break right by the waterfall. There is something calming about the place, and the light that falls through the trees transforms the surroundings into a true natural painting. The path is a bit rocky in some places, but the view and the silence are definitely worth it.

Where the two trails meet, walk a short distance to the right to reach this beautiful little waterfall.
