Boulters Lock and Ray Mill Island (SL6 8PE) both make a nice gentle walk with loads to see. Including Boulter's Lock itself where you can see boats coming in and out of the lock. You can then walk over a bridge from Boulter's Lock to Ray Mill Island and visit the small play area and wooden sculptures, aviary and guinea pig enclosure, watch the wildlife on the island and River Thames or watch the water cascade through Boulter's Weir. There is also a cafe on Ray Mill Island and Boulter's Bar and Resturant (which we have not tired yet). There is a play and display car park just up the road from Boulter's Lock.
