APRIL 2026 · ADVENTURE
Dunraven Bay to Cwm Nash Circular
Glamorgan Heritage Coast · Wales
The car park at Dunraven Bay sits above the beach, and the path out goes through the ruins of the estate — ivy-covered walls, a stream running through a mossy stone channel, ferns everywhere. The Victorian country house was demolished in the 1960s; what's left is atmospheric enough. A gate in a wire fence leads through scrub onto the cliff top. That's where the walk begins properly.
The cliff top path runs west toward Cwm Nash, about two miles. The Bristol Channel sits grey to the south. In April the gorse is in early flower. The path is well-worn but the edge isn't fenced — the limestone just stops and drops, sometimes to a sea stack, sometimes to a pebble shelf, sometimes directly to a rock platform at low tide. The cliffs here are Jurassic limestone, 200 million years old, folded and tilted, the strata visible in bands across the cliff faces below. You look down at what's waiting.
Not a colour you'd expect from limestone.
Dunraven Bay — April 2026
At Cwm Nash there's a descent path that takes you from the cliff top down to the beach. The stream that runs through the cwm drops over the cliff face as a thin waterfall — springwater more than rain-fed, seeping through moss-covered limestone. At the base of the fall there's a shallow pool. The algae in it was vivid green, the colour of lichen on a north-facing wall, completely unexpected against the pale grey rock. Not a colour you'd expect from limestone.
The return leg runs along the beach, back to Dunraven — only possible at low tide. The limestone platform is the draw: wave-cut ledges in flat steps, the rock fractured and tilted, the strata folding visibly in the cliff faces above. Further out toward the water, reef rocks rise from the sand — barnacle-encrusted, some coated in green weed, surrounded by shallow pools with sand ripples. The worm casts were what stopped me most. Clusters of them scattered across wet sand in a few inches of tidal water — precise, patient, impossible to hurry.
The dead tree on the cliff above Dunraven comes into view in the last half mile. Wind-bent, bare, silhouetted against a sky that had been moving all afternoon. It marks the end of the beach and the start of the climb back up.
