The rugged, rocky boundary between sea and shore is a playground for the well equipped and wild-spirited. Sign up for a coasteering adventure and climb, cliff-jump, splash, swim, and wave-ride through some of the U.K.’s most scenic landscapes. Wet suits, helmets, buoyancy aids, and other gear make the wild coast accessible. Pembrokeshire Coast National Park works with half a dozen outfitters eager to get you started.
