Porthgain to Abereiddi Coastal Walk, Pembroke
Follows dramatic clifftop paths along Pembrokeshire's volcanic coastline, passing turquoise sea, abandoned slate quarries and the famous Blue Lagoon at Abereiddi. Terrain is undulating with some steep sections and rocky steps—manageable for older children (8+) but not suitable for buggies or very young kids. Dogs welcome on leads near cliff edges. Stunning geology, industrial heritage and big Atlantic views make this a proper coastal treat, though exposed in high winds.
