It’s not hard to see why Tenby, in Pembrokeshire, is one of the most popular coastal towns in Wales. Not only does it have long stretches of white sandy beaches, but it also has significant historical sites, such as the 12th-century Tenby Castle and the medieval wall that surrounds the town. A smart way to enjoy a seaside break here is to go for a vacation rental or cottage as close to the beach as you can find. Good thing, then, that Tenby is well stocked with both. Here are the best, all bookable on Culture Trip.
