Sea kayaking reveals all the nooks and crannies of the coastline. The Cosquer cave, a major site of semi-sunken cave art near Morgiou, is the most famous underwater treasure of the coves.
The July 14 cave is an impressive underground maze bristling with stalagmites and stalactites, hidden in the bowels of the highest maritime cliffs in Europe, between Cassis and La Ciotat. Diving: spectacular underwater architecture, sculpted with caves and canyons, precious corals such as gorgonians, red or yellow.
