Vast sweeping bay ending in a tidal serpent headland.
A mile-long spine of rock trails off the tip of Rhossili into the sea: Worm’s Head, its name from the Old English word for sea serpent, or Pen Pyrod in Welsh. Closest to Rhossili is the Inner Head; beyond it, the Middle Head has a collapsed sea cave known as the Devil’s Bridge. Right at the tip, the Outer Head has a blowhole that sends spray up through the rock in rough weather. The National Trust looks after Worm’s Head as part of its Gower coastline, home to nesting seabirds and grey seals hauled out on the rocks.
You can only cross the causeway on foot for about two and a half hours either side of low tide, or you risk being stranded; check the safe crossing and return times posted at the coastwatch lookout above the causeway before you set out. Dylan Thomas once misjudged the tide as a young man and spent a night stranded out here, later calling it ‘the very promontory of depression’. Walk back to Rhossili for a long view over Rhossili Bay while you wait for the tide to turn.
