Dive-site story
Formerly one of the premier inland diving centers in the United Kingdom, this flooded limestone quarry near Chepstow features sheer vertical rock walls stepped down to exceptional depths. Submerged attractions line the various tiers, catering to technical deep training alongside open-water skill practice. Divers reach the water edge via a transport van descending a steep haul road to purpose-built pontoons.

Seasonality
Warmer surface temperatures make spring through autumn more comfortable, though winter dives offer clearer water due to lower diver traffic.
