Dive Dozzi Opening Dates And Times 2022

The chart below shows the number of spaces still available e.g. 7 means there are 7 buddy pairings left. 5.5 means there are 5 buddy pairings left + 1 diver if you opt to book a threesome.

You can’t amend the chart yourself.

During the BETA-testing of our Covid-19-Secure procedure we have increased availability to 15 pairs per 2-hour session. Subsequent weeks will be made available based on BETA feedback, and the number of buddy pairs may be further increased based on the success of the BETA testing, and further relaxation of the Government's Covid restrictions.

With, or while in contact with your buddy, refresh this webpage and check your preferred date & time for availability on this chart. Note what day & time has available spaces that are convenient for you and complete the form below the chart to reserve a 2-hour buddy dive session.

Only call Dozzi on the number above, at the stated times, if you have a query which can't be answered from the information on this webpage.

Welcome to Dosthill Quarry

The Oldest Inland UK Diving Site


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.
