NATIONAL DIVING AND ACTIVITY CENTRE Why not join us on one of our days to NDAC


The National Diving and Activity Centre is a large flooded quarry at Tidenham, Gloucestershire, England, near to the border with Wales at Chepstow. It was formerly Dayhouse Quarry, a source of limestone, which was flooded in 1996. The diving centre opened in 2003.

National Diving Activity Centre

Popular with technical and free divers due to the depths of up to 75 metres, with underwater attractions in depths ranging from 6 metres to 75 metres.

We usually run Deep and Technical courses here and always invite our divers to come along for the day and have a splash.
