Work the boulder beach either side of Col-huw Point on a falling tide. Freshly fallen Lias blocks carry crisp ammonites and oysters — search the recent falls from a safe distance out, where the sea has already spread them.
Ammonite impressions here can be dinner-plate size, showing as coiled ridges on fallen grey-blue slabs. 'Devil's toenails' (Gryphaea) are thick, curved oyster shells lying loose in the gravel. Free identification: photograph your find for the enquiry service at Amgueddfa Cymru — National Museum Cardiff.
This coast is a protected site (SSSI). What does that mean?
Allowed: Loose fossils from the beach and foreshore may be kept for personal collections.
Never allowed: No hammering or digging into the cliffs or the wave-cut ledges anywhere on the Glamorgan Heritage Coast.
Important finds: Report significant finds (this coast produced the Welsh dinosaur Dracoraptor) to Amgueddfa Cymru — National Museum Cardiff.
Rules can change — check locally before you collect.

Seasonal café and toilets at the beach.
