An indoor waterpark in Blackpool, Lancashire, operating year-round as one of the largest indoor water parks in the United Kingdom. Opened in 1986 on the South Promenade, Sandcastle provides water-based recreation independent of Blackpool's unpredictable weather, with a tropical indoor temperature maintained at approximately 28 degrees Celsius throughout the year. The park has undergone multiple expansions since opening, adding progressively more ambitious water slides and attractions. Major attractions include the Master Blaster, a water coaster that uses water-jet propulsion to push riders uphill as well as down; the Sidewinder, a high-speed enclosed tube slide; and the Aztec Falls, a multi-person raft ride through a themed darkened course. A wave pool, river rapids circuit, and multiple body and tube slides of varying intensity provide options across all age groups and thrill tolerances. A toddler-specific area offers shallow water play features. The indoor environment means that Sandcastle operates throughout Blackpool's long winter season, supplementing the seaside resort's traditionally summer-focused offer. This year-round availability makes it particularly valuable for the resort's significant out-of-season visitor market, including half-term school holidays and the autumn Blackpool Illuminations period. Located on the South Promenade approximately 2 kilometres south of Blackpool Tower, the waterpark is accessible by tram (South Promenade stop), bus, and car. Parking is available on site. The park can be combined with Blackpool Pleasure Beach, the Tower, and the Sea Life Centre for a multi-day Blackpool resort visit. Admission is discounted when booked online in advance. Birthday party packages, group rates, and school group educational visits supplement the standard admission model. A gift shop sells beach and pool accessories, and the park is accessible for visitors with reduced mobility through ground-level pool areas and adapted facilities.
