National Diving and Activity Centre (NDAC)

The National Diving and Activity Centre (NDAC) is a former limestone quarry in Tidenham, Gloucestershire, England, near the border with Wales at Chepstow. It has numerous underwater attractions in depths ranging from 6 metres / 20 ft to 76 metres / 249 ft.

The site has facilities including changing rooms, dive shop, kit hire, gas refills, an on-site cafe and licensed bar (for after your diving!), and on-site accommodation.

Features

NDAC features many wrecks – planes, boats, armoured vehicles, and even double decker buses that we can swim through! 

The site provides crystal clear waters, with training platforms at shallower depths and drop-offs to 40-75 metres and beyond for our more advanced technical training programmes. 

There’s even a zip-line going across the quarry for some spectacular post-diving thrills!
