Sandcastle Waterpark (Blackpool)

Sandcastle Waterpark is an indoor waterpark with 18 water slides and other attractions in Blackpool, Lancashire, England. Sandcastle Waterpark is also home to slides such as the world's longest indoor roller-coaster water slide, the Master Blaster, and the first vertical indoor drop slide, the Sidewinder. Family attractions include the Ushi Gushi Action River, the Shimmering Shallows and the Typhoon Lagoon Wavepool. For younger people there is the Caribbean Storm Treehouse, an interactive adventure play area with a large tipping coconut. There are also a range of water cannons, mini slides and jets within the HMS Thundersplash and Fort Riptide areas. History Sandcastle opened on 26 June 1986 on the site of the former South Shore Open Air Baths as a joint public/private partnership. Operation of the facility was taken back into Blackpool Council ownership in 2003. A significant investment in new attractions costing £5.5M was also agreed, which was delivered in two phases, with the second opening in 2006 on time and on budget. In 2012, Sandcastle opened two new Aztec-themed slides, one with a chamber called 'Aztec Falls', and a toboggan-like slide called 'Montazooma'. Sandcastle Waterpark celebrated its 30th birthday in 2016 with a monthlong series of events involving a variety of local charities and community groups. On 26 June 2016 as part of these celebrations, the waterpark regained the world record for most riders (529) down a waterslide in one hour. The previous record had stood to a Dutch waterpark at 396 riders. In 2022, management of the facility was awarded by Blackpool Council to Merlin Entertainments for a two-year period. By June 2025, Blackpool Council were operating the attraction in-house once again, and in August operation transferred to their new tourism company Blackpool Tourism Ltd.
