DEEP Campus,[1] previously the National Diving and Activity Centre (NDAC), was a facility located at a large flooded quarry at Tidenham, Gloucestershire, England, near to the border with Wales at Chepstow. It was previously Dayhouse Quarry, a source of limestone, which was flooded in 1996. The diving centre opened in 2003,[2] and closed in 2022.[3]
An inland scuba diving site, it was popular with technical and free divers due to the depths of up to 80 metres (260 ft),[4] with underwater attractions in depths ranging from 6 metres (20 ft) to 76 metres (249 ft). PADI and IANTD training was provided on site, and many local BSAC and SAA clubs used the site for training.[5] All freediving at the NDAC was undertaken through SaltFree Divers.[6]
The site also included an inflatable assault course,[clarification needed] bungee jumps, paddle boarding and a 700 m (2,300 ft) long zip wire.[3]
On 18 February 2022, the NDAC issued a statement via social media saying that the site was permanently closed.[7] The following month it was reported that the site had been purchased by a company seeking to develop equipment to enable people to live deep under water.[8] In September 2023 it was revealed that the site had been acquired by DEEP.[9]
In 2017, the NDAC was a location for the Netflix folk horror film Apostle starring Michael Sheen and Dan Stevens.[10]
