The Green Bridge of WalesDistance from Bluestone - 18.8 miles
Off Pembrokeshire’s south coast overlooking Wash Bay, structural marvels of nature stand against the surf. The towering arch of the Green Bridge of Wales juts out from the coast. Carved into the limestone cliffs by crashing waves and sweeping tide, the Green Bridge almost seems impossible in its majesty, and is testament to the power of the natural world. Formed over millennia via coastal erosion, the Green Bridge was formed as the sea carved caverns into the coast. Eventually, these caverns met and opened out into the archway we see today.
