Calypso Cove Waterpark, Barnsley

Calypso Cove is the indoor waterpark inside the Barnsley Metrodome complex, which makes it a dependable wet weather option in South Yorkshire. Named rides include Terror Torrent, Eruption, Kraken, Sunken Galleon and Splash Ahoy, along with Walk The Plank diving boards. Barnacle Bay is an interactive play zone set aside for younger children. It runs seven days a week with extended hours in school holidays, and the wider Metrodome has other facilities if you want to build a longer visit.
