On the 15th we took a 6 hour bus from Barcelona to Marseille.  We checked into our Airbnb and then walked around the touristy port area.  We ate doner kebabs for dinner.  On the 16th we ate breakfast at a local bakery and then explored the city.  Marseille is quite the melting pot.  On the 17th we took a few buses and finally arrived in the Calanques National Park.  We did a small hike and then went swimming/snorkeling.  We had lunch there as well.  We kept hearing gunshots while swimming.  Turns out they were shooting a movie out there.  It was fun to watch.  We went to Steak and Shake for dinner.
