Cemlyn Bay beach, Llanfairynghornwy, Isle of Anglesey
  • About Us

    Cemlyn Bay is a bay on the northwest coast of Anglesey to the west of Wylfa nuclear power station. The beach is pebble and has sand as the tide goes out, but most people don’t visit for the beach but what lies behind it. Separated from the beach is a brackish lagoon, which is fed by a number of small streams. A weir at the western (Bryn Aber) end of the beach regulates the lagoon’s water level.

    The site is designated a Site of Special Scientific Interest and is currently part of the Anglesey Heritage Coast and the Isle of Anglesey Area of Outstanding Natural Beauty. The Cemlyn estate is owned by the National Trust; the lagoon and its immediate surrounds comprise Cemlyn Nature Reserve (25.2 ha in extent, set up in 1971 and leased by the North Wales Wildlife Trust).

    Car parks at either end of the Cemlyn Bay and the Anglesey Coastal Path passes through the bay.
