Located in the east of England, at the top of 'the bump', Norfolk is usually famed for being a quiet farming county that attracts tourists (notably to the Norfolk Broads). While the flat, low-lying land is indeed conducive to farming, it also is responsible for the long, flat beaches that surround the Norfolk coastline and on a moonlit evening, one can walk for hours in peace. Several beaches host nature reserves and if you are in the right place, it is not uncommon to see seals bobbing in and out of the water. Being in England, these aren't the sort of beaches that you sit around and tan yourself on, but they have their own majesty in a very different way. Although many of the Norfolk beaches are appreciated, try out Holkham (where this photo was taken), Thornham, and Brancaster.
Note: Due to the flat land, tides are fast and large, so be careful not to get caught out too far as the tide is rising.
