Plymperis

Plymperis is a small, uninhabited island located in the Pembrokeshire Coast National Park, off the west coast of Wales. Situated in the Irish Sea, the island lies approximately 1.5 kilometers southwest of the mainland village of Porthgain and is part of the Preseli Hills. Plymperis is notable for its dramatic coastal scenery, rugged cliffs, and historical significance.

The island is a Site of Special Scientific Interest (SSSI) due to its ecological importance, particularly as a breeding site for seabirds such as the Atlantic puffin, razorbill, and guillemot. Its rocky shoreline and grassy slopes support a diverse range of flora and fauna, contributing to its conservation value. Access to Plymperis is restricted to protect its fragile ecosystem, and visitors are advised to stay on designated paths and avoid disturbing wildlife.

Historically, Plymperis has been associated with maritime activity. The island’s name may derive from the Cornish or Welsh words for "island" or "rocky place." In the past, it served as a navigational landmark for sailors. There are no permanent structures on the island, though remnants of old stone walls and possible remnants of past human activity have been observed. The island is also linked to local folklore, with tales of smugglers and hidden treasures occasionally mentioned in regional stories.

Today, Plymperis is primarily visited by boat tours departing from nearby coastal villages, offering passengers a glimpse of its untouched natural beauty. The island’s remoteness and lack of development make it a popular destination for nature enthusiasts, photographers, and those seeking solitude. Its proximity to the Pembrokeshire Coast National Park ensures it remains a protected area, preserving its wild character for future generations.
