From Marseille the seacliffs around the coast - Les Calanques - are easily reached by metro and bus and some minutes of walking. Here you can go for long walks and you will find some of the best sports climbing in all of Europe. The routes are generally very well protected. During midsummer walking and climbing is forbidden, but during spring and in the autumn the Calanques are open. The scenery is beautiful with white cliffs and a clear blue sea. The young Joseph Conrad left the old port of Marseille on his first ship.
