The River Wey at Artington meanders through the Surrey Hills like a gentle invitation to swim and linger.

Tall alders and willows dip their branches down so that when you wade in you feel embraced by foliage glinting in sunlit patches on the water.

The water is clear enough to glimpse the riverbed, but deep enough in places to let you dive a little and rise up with a splash of green around you.

3) River Thames (Marlow), Buckinghamshire

On the bend of the River Thames at Marlow, water flows wide and deep under a sky that seems to stretch forever.
