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!
