Tenby perches on a rocky promontory between two sandy bays overlooking the Bristol Channel.  It is a picturesque walled town with cobbled streets, a 15th C Merchant’s House and an interesting history.  Famously, Henry Tudor sailed into exile from the town, returning later to defeat Richard III at the Battle of Bosworth and found a new dynasty as Henry VII.  It’s a popular resort.  As well as the usual beach stuff, cafes and so forth, there are boat trips to nearby islands, water sports and walking on offer along the coastal path.
