Phare des Baleines

For an overview of the island, scale Phare des Baleines, the island's scarlet-tipped, 57m-tall lighthouse on its northwestern tip. Tackling the dizzying, 257-step spiral staircase inside the 19th-century lighthouse (1854) rewards with a sweeping coastal panorama. Learn its history in the neighboring Musée de la Mer and visit the lighthouse's shorter 17th-century predecessor, a 29m-tall tower now known as the Vieille Tour (old tower).
