This morning we drive to the tiny fishing port of Porthgain (Chisel Port) that used to export slate from the nearby quarry until the 1930s. There's also the remains of an impressive industrial dolerite stone crushing plant, making stone for road-building around 1870-1895. We start our walk here, re-joining the Coastal Path and walking east and north back towards our lodge. A short detour brings us to Carreg Samson - thought to be a 5,000-year-old Neolithic burial chamber with a massive capstone atop upright stones.
We reach a long, narrow picturesque inlet at the traditional fishing harbour of Abercastle, where the natural shelter makes it ideal for kayakers and boats. The trail leads on past more pristine coves, through heather and wild flowers. Hundreds of small islands and rocky crags lie off shore here and provide a perfect haven for seals and seabirds, especially in spring and autumn. After a steep descent and ascent to pass Pwllstrodur cove we reach Castell Coch, once the site of an Iron Age fort.
Finally, we reach the familiar sight of Abermawr Bay and the final short section inland back to our accommodation. Isambard Kingdom Brunel once planned a harbour and railway terminus for transport to Ireland at Abermawr Bay that thankfully didn't go ahead, and Fishguard was chosen instead. Today's moderate-graded walk will take approximately 4 hours and will cover a distance of 14 kilometres with a total ascent and descent of 640 metres. Stay: Preseli Venture Eco-Lodge (Simple) (B/L/D)
