The National Diving Centre or The NDC as it’s commonly known is a relatively new diver training venue located in Chepstow, which makes it convenient for both the M4 and M5.
Formerly known as Dayhouse Quarry, the NDC has a range of training depths from 3m down to 80m many of which are buoyed off and have tapezes. Having the varied range of depths makes it ideal for all levels of diver training from The PADI Open Water Course through to TDI Advanced Trimix Courses.
Up in the car park area you will find a well stocked shop, air fill facilities including nitrox and trimix to 100 bar, a cabin selling all the usual refreshments and there are toilet facilities.
There is a shuttle service which takes your dive kit down to the pontoon area, which runs every 20 minutes or so.
Under the water you will find many perch and pike as well as the ‘mandatory’ sunken wrecks with diving bells and boats etc found at different depths. At the surface you will find a 144 metre pontoon with many entry and exit points to the water so you will find plenty of space to kit up. They even supply you with trolleys to transport your kit (very useful after a deep dive!).
From a safety point of view the NDC have staff monitoring the lake constantly in case any divers fall into difficulties. They have a rescue boat ready in case of emergencies and also have an on sight recompression chamber.
All in all….. a great dive site for diver training!
