Underwater Easter Egg Hunt

Easter Egg Hunt at the NDAC Chepstow

The Easter Scuba Bunny has been busy hiding eggs under the water at the National Diving & Activity Centre.

If you’re diving with us over the Easter weekend and lucky enough to hunt down one of the Easter Eggs, bring it to the gas room and one of the NDAC team will exchange it for a chocolate Easter Egg.

6 Month Post-Lockdown reopening plan for NDAC

Wednesday, March 24th, 2021

NDAC Reopen from April

Update June 2021

The Atlantis Aqua Park is now open for bookings on selected dates.

We’re not currently selling Gift Vouchers for the Atlantis Aqua Park.


Following a review of the government guidance and consideration of how we can implement it throughout the National Diving & Activity Centre, we are excited to release our 6-month plan for reopening. 

Easter Weekend Scuba Diving

We’re pleased to announce that we will now be able to open for limited Scuba Diving over the Easter holiday weekends (3rd & 4th, 10th & 11th April 2021). 

We’ve established that providing we work to our Covid procedures, keep the Wigwams and changing rooms closed, and only provide takeaway food/drink, we will be able to open as originally planned. 

We apologise for the changing dates and appreciate the frustration some have experienced as we react to the developing government advice. With the easing of lockdown restrictions and the release of our 6-month dates, we hope divers will be able to make firmer plans to visit.

Anyone who has booked scuba diving on Friday the 2nd or Monday 5th April is welcome to contact us to change their booking dates to the 3rd/4th or 10th/11th April. Alternatively, we can provide a 6-month voucher or a full refund.

Scuba diving bookings previously made for the 3rd & 4th April are still valid.

We have also released the dates we plan to open for Scuba Diving over the next six months. Anyone who had a previous Scuba Diving booking cancelled due to Covid will be offered a 6-month voucher to rebook. 

We will be responding to customer emails in the next coming weeks to put all arrangements in place.


We are pleased to confirm that the Wire Zip Slide will be reopening in July and August. Our other activities (Giant 3G Swing, Atlantis Aqua Park and Cinema) will not be reopening for the remainder of 2021.

Anyone who has a Wire Zip Slide booking/voucher from November 2019 that has expired due to Covid19 will have their voucher automatically extended to use in July/August this year. Please use your existing voucher to make the booking.

For those with Giant 3G Swing, Atlantis Aqua Park and Cinema vouchers, you will be contacted in the next few weeks to offer a full refund or a Wire Zip Slide voucher as an alternative replacement.

Wigwam Accommodation

We are pleased to confirm that we are providing Wigwam accommodation on selected dates between 24th April and the end of August 2021. 

Anyone who has a Wigwam booking/voucher that has expired due to Covid19 will have their voucher automatically extended to redeem and use by the end of August. Please use your existing voucher to make the booking.

All extended activity and accommodation vouchers must be redeemed and used by 31st August 2021. After this date the voucher will expire and will be invalid. No alternatives, further renewals, refunds or other form of compensation will be made.

Opening Dates

For our opening plan for the next 6 months and beyond, please visit our Opening Times Page. All dates are dependent on government/Covid restrictions allowing us to open.
