Walk up the hill to Wray Castle and down to the lake to hop on a Windermere Lake Cruise to see Bowness, Ambleside and the Lake District Visitor Centre at Brockhole (01539 446601). It has an soft indoor play area and an outdoor adventure playground with rope walks, slides, zip wires and scramble nets, and you can hire a kayak for £10 an hour. A walkers’ ticket allows you to take a break at any of the stops and catch a later boat.
