Take the kids to Bowness Pier for some fresh air and sunshine. They'll have fun trying to spot fish swimming in the waters below or boats way off in the distance.
You'll have no end of sightseeing choices when visiting Windermere. Bowness Pier is a great place to start here, but there are lots of other worthy places to check out. Lake Windermere, Grizedale Forest, and Windermere Golf Club are close to the waterside attraction and will round out your day nicely.
