A young sailor is arrested at his own engagement party, thrown into a prison island, escapes in a dead man's burial sack, finds a hidden treasure and comes back as a count to settle accounts. This route follows Dumas's novel in order, from the Marseille lookout to the island where it ends.
Most of the stops can be visited; the island of Monte Cristo is a nature reserve with a years-long waiting list, and several scenes happen in places Dumas invented, so those pins mark the real landmark nearby.
Before The Little Prince, Antoine de Saint-Exupéry flew the mail. He flew the Aéropostale line from Toulouse, ran the Cape Juby airfield, directed an airline in Buenos Aires and survived a crash in the Sahara that later fed his most famous book.
The route follows his life in the air, from the take-off strip at Montaudran to the sea off Marseille where his plane was found. The Sahara crash site is only an educated guess.
