Located along the Dorset County shoreline, Durdle Door Beach is a popular and splendid pebble-and-pebble beach with clean water. This beach is situated below oceanfront blufftop headlands. An immensely popular natural limestone archway named Durdle Rock is also present near the beach. As an interesting fact, the name of the beach and the archway apparently comes from the Old English word "thirl" (meaning to bore or to drill). Durdle Door Beach is also a part of the Jurassic Coast, which is a section of the Southern English coastline that has been designated as a UNESCO World Heritage Site.
