What is the Couloir Samson? A Unique Geological Setting
The Couloir Samson marks the official entrance into the Grand Canyon of the Verdon. This is the exact spot where the limestone cliffs tighten in a spectacular fashion.
- The Stone Giant of the Verdon: The corridor takes its name from a colossal, human-like rock formation sculpted by time into the cliff face. According to local legend, this stone silhouette evokes the biblical figure of Samson, who supposedly pushed the mountains apart to carve a path for the river.
- Between the Paroi du Duc and the Escalès: At this precise location, the Verdon River snakes between two stone titans: the Paroi du Duc on the left bank and the Escalès cliffs on the right bank, towering nearly 400 meters vertically above the emerald waters.
How to Get to the Couloir Samson?
Logistical access to the site is very straightforward, whether you are stopping for a quick photo or heading out on an excursion:
- By Car: Take the D952 road between Castellane and La Palud-sur-Verdon to reach the large, designated parking lot at Point Sublime.
- The View from Above: From the parking lot, an easy walk of less than 10 minutes leads you to a secure observation deck for a dizzying, plunging view over the entrance of the corridor.
- Accessing the Riverbed: To hike down close to the water, take the trail that descends from the parking lot toward the Baou Tunnel.
Visiting the Couloir Samson on Foot: The End of the Blanc-Martel Trail
For hikers, the Couloir Samson is a place of deep emotion, as it serves as the final arrival point (or the starting point, depending on your direction) of the region's most famous trek: the Sentier Blanc-Martel.
The Impressive Trail Tunnels: Upon reaching the Couloir Samson via the trail, hikers pass through the famous Baou and Trescaïre tunnels. Carved into the rock at the beginning of the 20th century for old hydro-electric projects that were ultimately abandoned, they are completely dark today and require the use of a flashlight.
The Trescaïre Viewpoint and Metal Ladders: Along the path, you will pass metal footbridges and panoramic viewpoints where you can witness the raw power of the Verdon River as it rushes beneath gigantic limestone vaults.
Aqua Trekking: The Ultimate Experience Inside the Corridor
While looking down from the cliffs is magnificent, slipping into the river to swim through the corridor is an unforgettable adventure. The Couloir Samson is the premier spot in France to experience Aqua Trekking (locally known as Rando Aqua or floating).
How Does it Differ from Canyoning?
Unlike classic canyoning, which takes place in secondary mountain torrents involving vertical rope descents and rappelling, aqua trekking consists of following the current of the Verdon’s main riverbed. You alternate between walking over river pebbles, taking fun jumps (never mandatory), and, above all, floating on your back down the rapids.
Why the Couloir Samson is Perfect for Floating
Floating is the only way to access sections of the canyon that are completely unreachable on foot or by raft (due to the extreme narrowness and giant boulder clusters). Equipped with a full 5 mm neoprene wetsuit, a life jacket, and a helmet, you let the emerald water carry you along the base of 400-meter cliffs. Looking up from the absolute bottom of the canyon is a memory that stays with you for life.
Safety Conditions and Prerequisites
- Level: Accessible to beginners and families (generally from 10 or 12 years old depending on the specific route).
- Prerequisites: It is strictly mandatory to know how to swim and to feel completely comfortable in the water.
- Professional Guidance: Due to river currents, natural underwater siphons beneath the boulders, and the daily management of the upstream EDF dam water releases, this activity must imperatively be done alongside a professional river guide.
