Cerrig Bwich Glas

Cerrig Bwich Glas is a small, uninhabited island located off the coast of Caernarfonshire, Wales. Situated in the Irish Sea, it lies approximately 1.5 kilometers southwest of Porth Dinllaen, a popular seaside village. The island is part of the larger Bardsey Island group, which is a designated Special Area of Conservation due to its rich biodiversity.

Covering an area of about 5 hectares, Cerrig Bwich Glas is characterized by its rugged and rocky terrain. The island is mostly composed of slate and sandstone, with cliffs rising up to 30 meters in height on its western side. Its eastern side, however, features a more gentle slope leading down to the sea.

Due to its exposed location, Cerrig Bwich Glas experiences strong currents and is subject to the forces of the surrounding tides. Consequently, access to the island can be challenging and is generally only possible during low tide. The island is known for its diverse birdlife, providing an important breeding ground for various species including guillemots, razorbills, and puffins.

Historically, Cerrig Bwich Glas was used for grazing livestock, with evidence of old field systems still visible today. The island is also home to the ruins of a small chapel, believed to have been dedicated to St. Bwich Glas, a local saint. This adds to the cultural and historical significance of the island.

Overall, Cerrig Bwich Glas offers a unique and picturesque landscape, attracting nature enthusiasts and birdwatchers who appreciate its natural beauty and tranquility.
