Ogof Simdde is a sea cave located in Pembrokeshire, Wales. It is situated in a small bay near the village of St. Bride's, overlooking the Celtic Sea. The cave is accessible only during low tide and is known for its unique geological formations and stunning natural beauty.

The entrance to Ogof Simdde is a narrow opening in the cliff face, leading into a series of chambers and passages. Inside, visitors can explore a network of interconnecting tunnels, some of which are large enough to walk through comfortably. The cave is well-known for its impressive stalactites and stalagmites, formed over thousands of years by the action of dripping water.

The cave is also home to a variety of marine life, including seals, dolphins, and a wide range of sea birds. The surrounding bay is a popular spot for snorkeling and diving, as the crystal-clear waters offer excellent visibility. The underwater world is teeming with colorful fish, sea anemones, and vibrant seaweed.

Ogof Simdde is a designated Site of Special Scientific Interest (SSSI) due to its geological and ecological importance. The cave is carefully protected and visitors are encouraged to respect the fragile environment by not touching or removing any of the formations.

Overall, Ogof Simdde is a fascinating natural wonder, offering a unique opportunity to explore the hidden depths of Pembrokeshire's coastal landscape.

Stonechat The European Stonechat (Saxicola rubicola) breed in heathland, coastal dunes and rough grassland with scattered small shrubs and bramble, open gorse, tussocks or heather. The male's song is high and twittering like a Dunnock. Both sexes have a clicking call like stones knocking together.

Caer Aber Pwll (Caerau) Iron Age Fort The complex defences at Caer Aber Pwll (Caerau) define a simple promontory fort to the east and a more heavily defended promontory fort on the west, both utilising the defensive potentials of the steep coastal cliffs. The western fort contains at least one building platform and is enclosed by a complex of up to four banks and ditches thought to represent at least two periods of construction, of uncertain relation, extending over a roughly 172m front. The main, inturned, gateway can be made out on the far side of the earthworks.

A second enclosure on the east, about 48m by 34m, may be a fragment of an early enclosure, isolated by redevelopment, an annex, or a separate and later enclosure butting onto the primary work.
