The couloir Samson itinerary takes you to and from the entrance to one of Europe's largest canyons: the Gorges du Verdon.
From the Couloir Samson parking lot, descend to the Raquette (turnaround area at the 23A road) and then descend, again via a path (the GR4), to the end of the Blanc-Martel trail: the entrance to the Canyon.
In the Gorges, you follow the Verdon through tunnels (the Baou tunnel is 670 m long) to the Trescaïre towers: three rocky towers on the opposite bank. This is the end of the itinerary, but you can continue walking if you wish.
Please note that swimming in the Verdon is prohibited.

Don't forget your flashlight (or at least the flashlight on your phone) and a jacket: it's chilly in the tunnels! Puddles often line the tunnels.
