Hampton Pool

This south-facing, 36-metre open-air pool, with grassy areas for sunbathing, is open and heated to a balmy 28C all year round. Built in 1922, it was saved from closure in the 1980s by a group of local residents, who continue to take part in fundraising activities. The group has rebranded itself as the Poolside Swim & BBQ Club and holds swimming and social sessions outside of normal pool hours – anyone is welcome to join. It’s also possible to book moonlight swim sessions. Which is cool.
