Lying below the hamlet of Caim on the north-eastern tip of Anglesey is a shore of wave-cut platforms backed by limestone cliffs. Fossils can be found here - corals and brachiapods being common, but there's little else here and it's mostly underwater at high tide. As this is an SSSI, extracting fossils from the living rock is not permitted.
Access is from the west side of Caim, where a well-maintained path descends slowly through woodland closely following a small stream. At its end is a drop of about 15 feet to the shore. Several large limestone blocks immediately beneath protect a small patch of boulder clay from erosion. This last section can be difficult and you need to take care, but a way down can usually be found if you look - and proceed - carefully.
