Along the coast from Marseille to Cassis, there are some truly remarkable landscapes. Almost 20 kilometres of white limestone rocks, bright and clear azure water, small bays, and deep valleys make up Calanques or the French fjords. As a result of the soil and dry weather, the microclimate in the calanques is really unique. The highly porous and dry limestone is almost uninhabitable for plants -- only the toughest can survive in these conditions. Instead, lots of animals like rabbits, foxes, wild boars, lizards, and other reptiles inhabit the valleys. Temperatures are higher than in the surrounding areas in winter which make the calanques a perfect home for these animals. Even though access to the calanques is limited from the ground and is restricted in summer because of the high fire risk, you can easily get there by boat. Exploring this natural wonder is certainly worth the effort.
