As fishing villages go, the whitewashed cottages and tidy tearooms of St. Mawes, in southern Cornwall, feel like a stage set. In this quiet backwater, fishermen sell their catch on a quay, and in the evenings, you will find them drinking Cornish-brewed Betty Stogs ale while playing snooker at the St. Mawes Billiards &amp; Social Club.  How to Get There: St. Mawes is a five-hour drive southwest of London.
