Worm’s Head was historically named Wurm – meaning dragon, by viking invaders. It is shaped like a giant sea-serpent and marks the most westerly tip of the Gower. The headland is one mile long and the highest point is about 150 feet. The jagged and rocky causeway leading out to Worm’s Head is only exposed for about two and a half hours before and after low tide. A young Dylan Thomas made the mistake of falling asleep here and had to wait for the waters to recede again before returning to shore. Worm’s Head can be found on the Wales Coast Path at Rhossili.
