Prussia Cove is a secluded cluster of four small rocky inlets on Cornwall’s Mount’s Bay, steeped in smuggling lore and framed by dramatic cliffs and crystal-clear waters. Once the haunt of the notorious 18th‑century Carter family—led by John “the King of Prussia” Carter—the cove’s hidden caves and shingle beaches give off an otherworldly, timeless charm. It’s part of a protected Area of Outstanding Natural Beauty and SSSI, perfect for explorers who love rock‑pooling, wild swimming, and walking the South West Coast Path—though you’ll need to bring your own snacks, as facilities are minimal . With its old‑world cottages tucked into the cliffs and a haunting maritime heritage, Prussia Cove feels like stepping back in time.
