"At this Philippe Starck-designed hotel in the seaside resort of Pyla-sur-Mer, couples enjoy panoramic views of Arcachon Bay and the mesmerizing Dune du Pilat from their beachy-chic guestrooms. Most visitors flock to the area to climb the magnificent dune, which rises 374 feet above sea level, but we won’t blame you for lazing on the sandy beach, breathing in the head-clearing scent of the pine forest."
