Abereiddy Tower Situated on the Trwyncastell headland to the north of Abereiddi Bay. This tower, of uncertain usage (local information board suggests possibility of it being a meeting place for directors of the now defunct Abereiddy Slate Mine, or their ladies), lies just off the Pembrokeshire Coastal Path and gets comparatively few visitors. This is possibly because a "scramble" is required to access the headland, as coastal erosion is steadily severing the headland's link with the main peninsula.

The Blue Lagoon The Blue Lagoon is a large disused slate quarry, now filled with seawater through a breach in the outer wall. This is 25m deep, according to a nearby Pembrokeshire National Park information board. Despite the name, the water is always a distinct greenish hue, owing to the mineral content within the quarry.

The lagoon is a favourite for adventure groups practising Coasteering.

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.
