Splashing into Chepstow on the Atlantis Aqua Park

Splashing into our Chepstow lake is our inflatable water park attraction – Atlantis Aqua Park!

With 71 floating modules covering an area of 2650m², Atlantis Aqua Park is breathtaking in terms of size, fun and location.

What better way to spend the day than with family and friends, bouncing, hopping, jumping and diving all over our incredible floating Atlantis Aqua Park!

Will you take on The Wire Zip Slide?

The Wire is one of the UK’s longest, tallest and fastest zip slides, running the 700 metre length of the spectacular NDAC Quarry.

Launch yourself from the 70m high cliff edge and speed along the length of our 80m deep flooded quarry.

Reaching speeds up to 40 miles per hour this exhilarating ride will take your breath away!

New for 2021 we have two additional zip wires installed at the site, so now 4 of your family and friends can enjoy the Wire Zip Slide together!

Last updated 26th March 2020

Owing to the global coronavirus pandemic and based on the information available to us from the UK Government we believe that the significant risk that is posed to our staff, customers and the local community to which we serve requires us to take decisive action now.

We are a local business that operates predominately outdoors, which by nature is less risk than any other indoor facility.

However, we are mindful, that continuing to operate during this global crisis is not in the best interests of our customers and team at NDAC or to members of the public. It is therefore with a heavy heart we have decided to fully close operations to the public from 22nd March 2020 until further notice.

We would like to thank all our customers for supporting us over the years and we look forward to serving you again.  We would also like to thank all our staff and dedicated work force for their commitment and understanding during these really difficult times, and would like to thank all the UK Government services for everything they are doing for our country.  

Darren & Kaye

We will keep our Facebook page and website up-to-date with the latest information. If you have any questions, please get in touch.


Scuba Diving Equipment Servicing

The National Diving & Activity Centre is currently closed for all equipment servicing.

All booked-in scuba equipment servicing will be completed when the current restrictions are lifted.

We will keep customers informed via our website and social media as further information is released.

We would like to say a huge thank you for your continued custom and understanding during these difficult times for our country. We look forward to seeing you all again in the near future.

If you have any servicing enquiries, please contact us via email on . We are working from home, but will advise the best we can.

Keep safe and look after each other.

Ashley & Nat


Refunds information 

What happens to my booking/gift voucher?

We are confident that this crisis, although hugely challenging and difficult to bear for us all, is short term and we remain confident and hopeful that we will commence our outdoor activities and operations to you all again when it is safe to do so and in line with UK Government advice.

We will not be issuing refunds, but please rest assured, you remain very important to us and your booking with us continues to be valid and will merely be postponed until operations are resumed.

We look forward to welcoming you in the near future and to providing you with an extraordinary experience to remember please stay safe!
