Following the Government’s announcement, we will sadly be closing the National Diving & Activity Centre for the remainder of November.
Any bookings made for the lockdown period will now be deferred. We will not be issuing refunds, but will provide everyone with a deferral code that can be used to rebook when we reopen.
We would like to thank all our customers and staff for the support and understanding you’ve given us and wish you all well in the coming weeks.
We look forward to welcoming you all back in December when the lockdown ends.

Information and Instructions
Diving can be dangerous if the correct methods are not used, sometimes fatally.
All divers have the responsibility for their own safety.

Divers are reminded that they have the responsibility for the first actions to effect a successful rescue.

The white customer copy must be displayed in full so all details
are visible from your vehicle dashboard at all times. NDAC club
members must display their cark park
passes in the same way.
- Please make
sure you read and understand the information about the centre and
the depth of the water, which is displayed, on notice boards around
the centre. Staff will be more than happy to help clarify any points.
- You must be
no younger than 10 years old to dive at the NDAC. All junior participants/children
must be closely supervised by adults at all times and never left
- The NDAC risk assessment is available from the shop. You are encouraged to consult this document and always to dive fully in accordance with the safe diving practices of your diving agency (e.g. PADI, BSAC, SAA, TDI/PSI etc.).
- Always dive
within your qualification level.
- Divers are
requested to plan their dives carefully. The diving site is 60metres
above sea level. Can all divers take this into consideration and
dive according to any impact it may make to your dive plan from
your training organisation i.e. PADI, BSAC, SAA etc.
- Solo diving
is not permitted. If you become separated from your buddy ascend
without delay and notify an NDAC member of staff with immediate
- Do not dive
below 50meters on Air or Nitrox.
- Do not dive
below 30 meters without a torch.

- Use a pony or
other reserve cylinder below 30 meters.
- Yellows SMBs

- No unauthorised vehicle access to the turning circle or haul road unless agreed by NDAC in advance (except for emergency and NDAC vehicles).
- Keep at least 3 metres away from the quarry walls at all times, above and below the water.
- Underwater training
platforms (see site map) are provided
for training purposes. Non trainees should be aware that students
are using these areas and may wish to plan dives avoiding such areas
at busy times (weekends).
- A number of
underwater attractions have been provided
at the NDAC (please refer to underwater
map or the attractions page for
more info). Divers enter or otherwise interact with the attractions
at their own risk.
- Do not enter an overhead environment unless you are properly trained to do so. Due to their confined space, these areas can silt up very quickly and do become hazardous without proper training.
- Diving in cold
water has resulted in many preventable incidents at freshwater sites
due to regulator freezing and divers wearing inadequate thermal
protection. The daily water temperature is available on the site
map, internet, or from a member of staff. Note that the water is
likely to be several degrees colder at depth than it is in the shallows.
Please refer to your owners handbook for information on using
your equipment in cold water. Please also observe recognised safe
diving practices that will minimise the risk of regulator free-flows
and maximise the adequacy of your response should a free-flow occur.
- Notices will
be published throughout the site when the centre is being used for
activities other than diving. Certain areas of the quarry may be
put Out Of Bounds (OOB) to divers while activities are being conducted.
- Do not dive
outside the displayed opening times.
- Speak to any
of the centre staff if you are unsure about anything on the site.

Arrangements at NDAC
First-aid, rescue and emergency procedures have been put in place at the NDAC. The Centre staff will make every effort to respond as quickly as they can to any emergency on the site both in and out of the water. We also conduct emergency rescue and casualty evacuation drills periodically to test the effectiveness of our arrangements. Any incidents or dangerous occurrences WILL be reported to the relevant enforcing authority in accordance with our statutory duties. In the event of an accident alert the staff immediately.
On the surface. Raise the alarm at once by blowing a whistle, shouting and waving or by pressing one of the emergency panic alarms buttons situated on the floating pontoons (please refer to site map for location). We also have an intercom system situated on the pontoons, outside the shed, that will allow you to speak directly to a member of staff.
If you see
anyone underwater with a problem wherever possible, help them to
the surface and raise the alarm at once by blowing a whistle, shouting
At the waters
edge if you see anyone in trouble, raise the alarm at once by blowing
a whistle, shouting and waving. While someone else alerts the centre
staff, stay where you are, monitoring the person in the water until
the person in trouble has been reached. Please then follow directions
given by the centre staff.
Diver Recall Signal. In the event of an incident that requires all divers to exit the water, members of staff will pound a heavy metal object against the side of the metal ladders at various points along the pontoon. If you hear the diver recall signal, make a safe ascent and exit the water by the nearest exit point. Please listen out for the signal at all times when underwater.
DO NOT RUN,
OR BLOW WHISTLES unless there is an emergency.
Full NDAC Emergency Procedure>
Please avoid the area around and underneath the Saltfree Freedive pontoon when their A flag is flying and they are diving.
In particular we request that divers do not use the Freedive mooring lines for decompression stops. If the freedivers had to release their counterweight in the case of an emergency, there is the risk of being caught by a 60kg weight.
If you are using any type of re-breather use a Surface Marker Buoy
(SMB) throughout your dive. However please note that yellows SMBs
should only be used in emergencies.
Do not dispose
of Sodalime or any other scrubber material on the site.

Safety Advice at NDAC
Please ensure when you arrive on site you only park your vehicles in the designated parking areas. The courtesy vehicles will shuttle you and your kit down to the diving platforms. The shuttle service runs throughout the day. No vehicles are permitted onto the turning circle area at any time (except emergency services). Do not cause an obstruction with your car or equipment.
We have a kitting up area in the car park. This is where the courtesy vehicles will pick you up and return you following your dive. Please be courteous of other divers on the bus and their equipment when loading and unloading.
We also provide kitting up areas on the pontoons. Please ensure ALL diving equipment is kept clear of walkways and kitting up benches to help other divers enjoy free movement on the pontoons and maintain access for emergency services. Any Equipment left on the pontoon that is seen to be causing obstruction, will be removed by NDAC staff.
Neither NDAC ltd or its staff will take liability or responsibility for any dive equipment damage or loss, however caused, when using the courtesy buses or pontoons.
