By far the smallest of the country's three national parks, Pembrokeshire Coast is no less strikingly beautiful than the other two. The park has 13 Blue Flag beaches and a host of spectacular clifftop drives and walks, including some of the most popular stretches of the Wales Coast Path. The park has a smattering of historic sites, including the impossibly picturesque St. David's Cathedral, built in a Viking-proof nook by the Irish Sea. The information center in Tenby is a good place to start.
