Waterworld is Bundoran's indoor water park and the town's main wet-weather family attraction. It sits right on the waterfront and offers a range of water slides, wave pools, and leisure pools that make it a reliable choice when the Atlantic weather turns grey — which it does regularly.
The park has been a Bundoran institution since the 1980s and is well maintained. It's primarily aimed at families with children, though the wave pool and slides attract teenagers and adults too. Entry prices are reasonable by Irish standards. In July and August queues can build in the afternoon; arriving in the morning avoids the worst of the crowds.
