Accessible to travelers via short boat ride south from Marseille, Riou Island is a beautiful uninhabited reserve that offers visitors access to rugged natural scenery and ample Mediterranean diving. The beaches that dot the island's northern and eastern edges act as perfect launch spots, not far from the Grand Congloue island where Jacque Cousteau discovered two impressive Roman shipwrecks in the 1950's. Due to the water's relative calm and clarity, however, it's perfect for just snorkeling, kayaking or swimming as well.
If you feel like getting out onto the land, Riou's limestone calanques offer a ton of unique hiking and climbing possibilities that aren't likely to disappoint. Venture to the 12th century watchtower ruins to get the kinds of stellar white stone on blue water vistas that have made this area of southern France so popular, or just forge your own trail along the barren, beautiful rock face. Definitely worth a visit.
