Splash Belfast is a large outdoor adventure water park located in rural County Antrim, Northern Ireland, near Moneymore. Set around a spring-fed quarry lake, it operates as an open-water activity centre rather than a traditional chlorinated water park. The site combines natural surroundings with structured water-based recreation, creating a distinctive outdoor experience in the countryside.

The park, known as Splash Outdoor Water Park, features a floating inflatable aquapark on the lake alongside activities such as kayaking, paddleboarding, and open-water swimming. Visitors can climb, jump, and slide across inflatable obstacle courses, or take part in more relaxed water sports across the lake. The facility also includes lakeside saunas, changing areas, and basic visitor amenities, supporting full-day outdoor use.

What makes Splash Belfast particularly appealing is its focus on natural adventure and active recreation. Instead of conventional pools and slides, it offers a more physical, outdoor-oriented experience in clear open water surrounded by rural scenery. It is especially popular for group outings, summer activities, and those looking for a mix of water sports and outdoor challenge in a natural setting.
