Hyde Park has a fleet of rowing and pedal boats which operate on the famous Serpentine and the UK's first Solarshuttle, a magnificent vessel which glides silently across the lake powered only by the sun.

Open-air swimming is internationally famous on Hampstead Heath with the Ladies' Pond, the Men's Pond, the Mixed Pond and the Parliament Hill Lido.

Brockwell Lido - your first choice for the whole family to stay fit and active in in south London.

Located in the heart of London’s Docklands at the west end of Millwall outer dock, the Centre is based in an award winning purpose built facility with great views from the upstairs bar over the dock, and wet facilities downstairs.
