Most leisure centres in Cardiff, capital of Wales, are owned by Cardiff Council. Since 2016, the running of eight formerly Council-run leisure centres has been outsourced to Greenwich Leisure Limited, operating under their 'Better' branding. Channel View Leisure Centre continues to be managed by Cardiff Council, whilst the Cardiff International Pool in Cardiff Bay is run separately by another private company.

Cardiff Bay is an area and freshwater lake in Cardiff, Wales. The site of a former tidal bay and estuary, it is the river mouth of the River Taff and Ely. The body of water was converted into a 500-acre (2.0 km2) lake as part of a UK Government redevelopment project, involving the damming of the rivers by the Cardiff Bay Barrage in 1999. The barrage impounds the rivers from the Severn Estuary, providing flood defence and the creation of a permanent non-tidal high water lake with limited access to the sea, serving as a core feature of the redevelopment of the area in the 1990s.
