Lovely place to visit, you can hire a boat for a few hours or a day. Highly recommend
The Norfolk Broads, around 40 minutes away, are a series of waterways and lakes. The best way to see them is by boat. You could hire a day boat and stop at some of the lovely pubs by the water. Lots of birdlife.
Beautiful area to visit for water sports, including sailing, kayaking and canoeing.
