Oasis Sports Centre

A 27.5m expanse of blue, the outdoor pool at the Oasis in Covent Garden is a central London revelation to the uninitiated. Once you’ve discovered the open-air heated pool, sun terrace and adjacent indoor pool you’ll be hooked, just like everyone else who’s in on the secret. The Oasis is so popular at hot summer weekends and at peak times that getting any serious swimming done is difficult – best go with the modest aim of splashing about to cool down. The outdoor parts were refurbished in 2011, with new steps to the sunbathing terrace, where there are separate areas for adults and families, and decking beside the café which serves smoothies and ice creams. Swimming is free for Camden residents aged 55 and over between 9am and noon Monday to Friday.
