Carreg Herefio is a small island located off the coast of Pembrokeshire, Wales. It is situated in the Irish Sea, approximately 2 miles southwest of St David's Head. The island is known for its rugged beauty, with steep cliffs and rocky shores.

Covering an area of about 8 acres, Carreg Herefio is uninhabited and largely inaccessible to the public due to its treacherous terrain. The island is mainly composed of volcanic rock, which has eroded over time to create fascinating formations and sea caves. It is a popular spot for seabirds, including puffins, guillemots, and razorbills, which nest on the cliffs during the breeding season.

The island is also home to a small population of grey seals, which can often be seen basking on the rocks or swimming in the surrounding waters. Due to its remote location and limited human presence, Carreg Herefio is an important conservation area, providing a protected habitat for these marine species.

Visitors can catch a glimpse of Carreg Herefio from the mainland, particularly from vantage points along the Pembrokeshire Coast Path. However, landing on the island is not permitted without prior authorization, as it is part of a designated Site of Special Scientific Interest.

Overall, Carreg Herefio offers a captivating glimpse into the natural beauty and biodiversity of Pembrokeshire, making it a must-see for nature enthusiasts and wildlife lovers.

Ruin near Aber Bach The ruined cottage is located by the path to Aber Bach beach between Garn Barcud and Aber-bach cottages, on the north side of the valley above Felin Fawr (Great Mill). This is the front view of the ruin which was abandoned around the late 19th century. It is not marked on present OS maps, but on the 1889 OS map (1:2500), the name Temple appears between Garn Barcud and Aber-bach. In the 19th century census returns for the parish of Granston, the name Pantyffynnon appears between Garn Barcud and Aber-bach cottage entries. The last record of occupants living in Temple or Pantyffynnon was in the 1881 census.
