Tony's Crack is a West Clare shore dive in Kilkee built around a narrow underwater canyon with walls on both sides, a kelp-topped exit, and plenty of small cracks and nooks to inspect. It feels more like a careful rocky traverse than a wide open reef, and the appeal is the combination of structure, kelp, and marine life packed into a compact site. In settled Atlantic weather it can be a very clear, rewarding dive with a straightforward top-out at the kelp line.
