This is why Marseille and Cassis are so well known. There are several Calanques (cliffs dropping into the sea) that are only accessible by boat or by hiking in. The cliffs extend up to several hundred feet above the water in crazy formations, not to mention the breath taking clear blue water below.
We have gone to the Calanques by boat and by hiking but everytime we go to Marseille visiting the Calanques is a must. Isn't it beautiful? Swimming in these little oasis' is like a dream.
