The walk from Caerfai Bay to Porth y Rhaw is a short coast path walk easily accessed from St Davids. It’s a round a mile along the coast path and so a 2 mile round trip.
Caerfai Bay has red an purple banded sandstone cliffs, historically quarried to make some of the older local stone buildings including the Cathedral.
The walk includes moderate terrain with some small climbs and rough ground underfoot so good footwear is a good idea for this walk. The views are spectacular across the amphitheatre of St Brides bay with beaches like Newgale, Broad Haven and Musselwick Sands visible around the arc of the bay finishing at Skomer Island.
Flora and fauna include plants such as sea thrift and sea campion. Also birds and animals like peregrine falcons, dolphins, grey seals and gannets. Also horses are grazed semi wild on the cliff tops at some times of year.
Porth y Rhaw Fort
After a mile of walking, the remains of Porth y Rhaw fort come into view. This Iron Age promontory fort, perched on a narrow headland, dates back over two thousand years. Though much of it has been lost to erosion, you can still make out the defensive ditch and banks that once protected its inhabitants. The fort’s position is strategic, with steep cliffs on three sides making it naturally defensible. Standing here, it’s easy to imagine why Iron Age peoples chose this commanding site.
On the way back you can see Ramsey island and the coves in-between as you walk north back to Caerfai Bay.
