Freshwater quarry dive with easy training features.
Freshwater quarry dive with easy training features.
Cromhall Quarry is an inland training dive in South Gloucestershire with clear freshwater and a compact layout of submerged attractions. Divers move between platforms, vehicles, and quirky objects such as telephone boxes and aircraft pieces rather than following a long natural reef line. The site works well for controlled skills practice and easy shore access, with the main planning issues being cold water and seasonal visibility.

More useful for open-water training and swimming than for a snorkel-first outing.
