Dive-site story
Set within a former limestone excavation in South Gloucestershire, Cromhall Quarry serves as a popular inland training water. The basin features submerged attractions connected by guide lines, ranging from sunken vehicles and a telephone box to training platforms and aircraft wreckage. Silt-covered bedrock terraces step down into the deeper sections, flanked by steep quarry walls.
Designated habitat for protected native white-clawed crayfish
Multiple submerged training platforms and vehicle attractions linked by navigation lines
Calm inland conditions sheltered from coastal swells

Seasonality
Summer and early autumn provide warmer upper layers, though underwater visibility is frequently clearer in the colder spring and autumn months when training traffic and algae taper off.
