Tooting Bec Lido

South London’s vast pool, with its iconic, Pantone-coloured changing huts, has been treasured by fortunate locals since it opened as a bathing lake in 1906. At just over 90m, it’s this country’s largest outdoor freshwater pool and inspires devoted swimming all through the year, although to swim in winter you must be a member of the well established South London Swimming Club, which has been based at the lido almost as long as it has existed. Facilities include a paddling pool for kids, a café, and lockers for small valuables.
