Looking for the ultimate way to let off that extra chocolate energy over Easter? We’ve got you covered!

Whether they’re practicing their paddles or just having a splash, it’s the perfect half-term activity right in the heart of Cardiff city centre. High energy for them, and maybe a little poolside peace for you? (We can dream!) Find out more at Flex reception (on the 2nd floor)
