"Cromer and Sheringham are renowned for their crab fishing and shingle/sandy beaches. You can often see the traditional fishing boats drawn up on the beach and today's catch being brought ashore. Both towns have a small museum and Saturday market... Sheringham has the 'Sheringham Little Theatre' which has a popular summer repertory season."

]. There's also the Sheringham Pleasure Railway. It's a pretty quiet place, all in all. See also: http://www.at-sheringham-norfolk.co.uk/whatson.htm
Theres a swimming pool there as well, seem to remember it being really good when iwas younger. Probably rubbish now.
Also Sheringham park... it has lots of rhododendrons as I remember!!
