The park holds two natural reserves predating the park itself, Annagarriff (77 ha) and Mullenakill (22ha), established in 1980. Of the two, Annagarriff is thought to be home to the only colony of Scottish wood ants in Ireland.
It also holds a 3 ft (914 mm) narrow gauge railway established in 1901 and displays an outdoor turf-cutting site. The park is also used as a venue for bog snorkelling.
