Vobster - http://www.vobster.com/
Located south of Bath. You can usually park close to the water so entry/exit is very convenient. There is refreshment available and a good dive shop on site. Underwater there is a nice swim at around 12m with aircraft swim-throughs and a large tunnel swim-through from about 18m up to 13m. Also a large area suitable for AOW depths with boat, wheelhouse, armoured car and some other attractions. Viz can be a variable due to the silty nature of the quarry. Entry usually giant stride and exit is via a slope or ladders. Equipment hire available.
Chepstow NDAC - http://www.ndac.co.uk/
Located just over the old Severn bridge (toll). Very good café with indoor seating. You have to use a ‘minibus’ service to get down to the water which is not ideal but the underwater experience is generally very good. Good visibility and lots to see at OW and AOW depths including armoured vehicles and pipe swim-throughs at shallower depths (narrow) and aircraft swim-throughs at AOW depths. It is the deepest inland site with 80m or more available at one end (over a wall). Entry is off a pontoon and exit is by ladder or a slope. Good for preparing for deeper dives. Equipment hire available.
Stoney Cove - http://www.stoneycove.com/
Located in south west of Leicester. Very good shop and café/bar with indoor seating. Access to the water is excellent with multiple entry and exit points. Good visibility and lots to see at OW and AOW depths including a 'submarine', the Stanegarth, a Wessex helicopter, a bus and mining relics. There is diving suitable for trainees and new divers at about 7m, with diving available to 35m maximum. It is the busiest of the inland dive sites, particularly at week-ends. Parking is a short distance from the main dive entry points, so you will have to carry gear a few hundred yards to the waters edge. Good for skills and some mid-depth dives in preparation for UK sea diving. Equipment hire available.
