The National Diving and Activity Centre

About Us

The National Diving & Activity Centre is based just outside Chepstow near the beautiful Forest of Dean.  We're a 5-minute drive of the M48 Severn Bridge, which is now free to cross!

We offer a wide range of activities and events throughout the year, as well as glamping accommodation in our Wooden Wigwams, Food & Drink in the View Cafe Bar and spectacular views over our lake.

This hidden gem is well worth a visit, why not pop in for a coffee and see what it's all about.

Atlantis Aqua Park

The Atlantis Aqua Park is breathtaking in terms of size, fun and location. The aqua park has over five floating zones to choose from. Within each zone it has an increasing intensity, so you can challenge not only yourself but also your stag/hen party to an experience like no other.

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

Just a reminder you will get wet... very wet!

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 NDAC Quarry in Chepstow.

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!

Giant 3G Swing

Experience weightlessness 245 feet in the air on our ultimate adrenaline-pumping blast!

If you dare, you'll be strapped into the Giant 3G Swing, hoisted 50ft up into the air and slowly pulled back to the release point...

Then it is down to one of you to pull the ripcord!

After the initial terrifying drop, you'll launch into the air, feeling the G-force as you swing up into the sky, 245ft over the steep quarry edges of the UK’s Deepest Inland Dive Site.

And There's More...
