Serpentine Lido

Early mornings and the winter months are the preserve of the Serpentine Swimming Club, but from May to September there's a warm welcome for everyone in this section of the Serpentine lake - although the water is not heated. It's not chlorinated either, a boon for swimmers who prefer to avoid the stuff, as well as to the wildlife (you may find yourself sharing a dip with the local ducks and swans). The gated family area with a (chlorinated) paddling pool, sandpit and swings means parents can relax while their children play. There's a private sunbathing area and sun loungers for hire and a kiosk within the lido grounds makes it possible to order from the popular Lido Café next door.
