Why it's Wildland
8.8Three limestone pinnacles frame a bay where sand, dunes and saltmarsh meet a winding stream, with the ruins of Pennard Castle above the valley.
The appeal is the rare combination of sculpted limestone cliffs, a winding green valley, broad sands and a ruined medieval castle in one coastal walk. It rewards taking time to explore beyond the beach, but tides and loose sand make planning important.
