Covering approximately 50 hectares (120 acres), sections of the park are laid-out over a former city landfill, while the eastern part of the park is located on the estate lands of the former Finglaswood House.[3] Some of park's wooded areas were planted in 2011,[3] while the wetland sections of the park were developed in 1999.[2] These "integrated constructed wetlands" were built at the confluence between the Finglaswood Stream and River Tolka, and designed to improve water quality and reduce pollution in the watercourse.[4][5] Sections of the River Tolka, within the park, have been stocked with salmon and trout.[6]
There are sports pitches, a par-3 municipal golf course,[2] and a pitch and putt course on the site.[7] As of 2018, it was reported that some of the park's sports pitches had been damaged by "scrambler bikes",[8] with issues of anti-social behaviour sometimes reported in the area.[9][10]
