The lighthouse, built by a French architect in 1910, stands at the island's far northern end. Although you can't go inside, you can ascend the hill to the lighthouse base for some great views. In this stark landscape, you might feel as though you've just landed on the moon. The lighthouse is surrounded by huge boulders that look like extraterrestrial monsters and sand dunes embroidered with scrub that resemble undulating sea serpents.
