Worm's Head Cave, RhossiliLike a mouth carved into an otherwise blank and towering face of a beast, Worm's Head Cave, once fronted by a raised beach, is now one of the more inaccessible of Gower's caves. Lying near the base of the sheer cliff face, about 4.5 metres above the high water mark, this is a very dangerous cave to access and only experienced cavers should attempt to reach it. The entrance to the cave is fronted by a ledge of rock and stands 4 metres high. From here, a passage leads into a large chamber and a second passage that burrows deep into the rock.
Despite its location, the cave has been excavated and finds there have included human bones from at least three individuals plus animal remains of wolf, fox, bear, reindeer, cat and bird. Flakes of crafted flint and a rhyolite blade have also been excavated from the cave. Today, the cave's main occupant is the cave spider Meta menardi.
Given its location and difficult access, it is not surprising to find that the cave has a legend attached to it, noted as far back as the reign of King Henry VIII. The legend has it that deep with the cave there is a heavy door, driven shut with many large nails. Behind this fabled door was believed to exist an underground passage with spacious walks connecting the cave with another at the head of the Gwendraeth Fach in Carmarthenshire.
