The Calanques National Park
If you have the good fortune to see the striking blue waters of the Calanques de Cassis along the French coast, please don't wait in the tourist line to pay for a boat tour. Muster up the courage to go for a mini, day hike. Walk to Port-Pin for the best swim of your life. Plunging into the cool waters of the fjord will be reward enough. It's not that hard, you'll be fine. If I can do it, you can do it.
