Welcome to Dosthill Quarry

The Oldest Inland UK Diving Site

See all our opening times. 

This, the first of the National Inland Dive Sites, has been operating since 1958
… and is popularly known as Dozzi.
I’ve owned the site since the British Sub-Aqua Club (BSAC) sold it to me in 1988.
Many divers and swimmers consider it to be the prettiest national site in the UK.
I hope you enjoy your time at Dozzi.
