Why it's Wildland
8.4At the end of Rhossili Bay, Worm’s Head stretches out as three limestone heads joined by a causeway that the sea regularly covers. On the Inner Head, an Iron Age enclosure remains visible; farther out, a collapsed sea cave forms Devil’s Bridge.
This is more than a dramatic headland view: the route crosses a landscape reshaped by the tide, past an Iron Age enclosure and the striking natural arch of Devil’s Bridge. Its changing access makes tide planning part of the experience, not an afterthought.

The experience
Plan around the tide, walk out only when the causeway is safely exposed, and look for the Iron Age enclosure on the Inner Head and Devil’s Bridge farther out. Conditions and access windows matter; check current local information before setting off.
Things to do
Time the causeway crossing
Check the tide information at the causeway and only cross within the safe access period. The route is exposed around low tide and can be cut off by the sea.
Look for the Iron Age enclosure
An Iron Age enclosure can be seen on the flat top of the Inner Head, according to the Coflein site record.
Find Devil’s Bridge
On the Middle Head, look for the arch formed by a collapsed sea cave. Reaching it requires crossing the rocky causeway and should only be attempted when access is safe.
Notice the caves and blowhole
Coflein records several caves on the Outer Head, including one that forms a blowhole. Observe from a safe position and do not approach exposed edges or openings.

Verified history
Coflein records an Iron Age enclosure on the flat top of the Inner Head. The same record describes Worm’s Head as a limestone natural feature made up of Inner, Middle and Outer Heads, with Devil’s Bridge formed by a collapsed sea cave. The supplied sources do not establish further dates or a fuller history of the enclosure.
Folklore & legend
Visit Wales says the name ‘Worm’ comes from the Viking word for a sea serpent. It also recounts that the poet Dylan Thomas was marooned there until midnight as a boy. Treat the name origin and anecdote as reported accounts, not as independently verified facts from the supplied archaeological record.
Hidden details
An enclosure on the Inner Head — The flat top of the Inner Head preserves a visible Iron Age enclosure, an easily missed archaeological detail amid the coastal scenery.
A collapsed cave makes the bridge — Devil’s Bridge is not an ordinary rock arch: Coflein identifies it as the remains of a collapsed sea cave.
A cave that becomes a blowhole — The Coflein record notes a cave on the Outer Head that forms a blowhole. Keep a safe distance from the exposed coastline.
When to go
· Around low tide, but only within the safe access window shown locally. Check the tide board and current conditions before crossing.
The defining constraint is the tide, not a verified seasonal peak. The supplied sources do not establish a best month or season.
Coastal conditions can change; check current conditions and tide information before setting out. The supplied sources do not provide specific weather thresholds.
