About Trearddur Bay

A small selection of sea cliffs on the west coast of Holy Island with adventures at all grades. The showcase crag, Face of Adversity, is a steeply overhanging sea cliff. Rock is the same quartzite/meta-sandstone of the South Stack Formation as Porth Dafarch and Gogarth South. Includes the nearby Lon Isallt cove. Seasonal seabird nesting restrictions can apply to some sections during spring/summer — check BMC RAD before visiting.
