Why it's Wildland
8.1A long, sea-serpent-shaped headland reaches out from Rhossili Bay, becoming an island when the tide covers its rocky causeway. Its three linked sections include the Middle Head and a collapsed sea cave known as the Devil’s Bridge.
Worm’s Head makes a coastal walk feel like an expedition: the route crosses a tidal causeway to a dramatic, rugged headland, with the tide itself setting the limits of your visit. The access window demands planning, not guesswork.

The experience
Plan around the tide, then walk out from Rhossili across the rocky causeway and explore only within the safe crossing window. The full out-and-back is described as a moderate coastal walk with rocky sections; check tide times and conditions before committing.
Things to do
Walk to the old coastguard station
Take the headland approach from Rhossili and use the old coastguard station as a shorter out-and-back objective. The supplied guide gives about 1.3 km from the car park to the station.
Around 1–2 hours return; allow for your pace and conditions.
Cross the tidal causeway
Reach the island over the rocky causeway only during the reported safe window around low tide. Check current tide times and local guidance; do not rely on an approximate timetable alone.
Allow several hours for the full walk; the supplied guide estimates 3–4 hours for its 7.5 km out-and-back.
Look for the Devil’s Bridge
On the Middle Head, look for the collapsed sea cave known as the Devil’s Bridge, described in the supplied visitor information.
Watch for grey seals
The supplied visitor information mentions regular grey seal sightings along the surrounding coast. Keep a respectful distance and do not assume a sighting is guaranteed.

Verified history
The supplied visitor information describes Worm’s Head as a roughly one-mile limestone headland and tidal island formed from three linked sections, with a rocky causeway and a collapsed sea cave on the Middle Head known as the Devil’s Bridge. No dates or further history are established by the supplied sources.
Folklore & legend
A supplied walking guide says the name is associated with the Norse word “Wurm”, meaning dragon, and relates a local legend that Viking invaders saw the headland as a giant sleeping sea-serpent. The same guide says a blowhole is said to boom and hiss in stormy weather, reinforcing the dragon story; these are presented as legend, not verified history.
Hidden details
The causeway is the crucial part of the plan — The guide reports that the rocky causeway is accessible only for about 2½ hours either side of low tide. Check current tide information and local notices before crossing, and plan to return within the safe window.
A cave feature on the Middle Head — The collapsed sea cave known as the Devil’s Bridge is identified on the Middle Head in the supplied visitor information.
