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.
