The trail is named after Édouard-Alfred Martel, who led the first successful exploration of the Verdon Canyon in 1905.
The route passes through two dark, unlit tunnels carved into the canyon walls that remain from an abandoned early 20th-century hydroelectric project.
The trail elevation drops and climbs significantly, resulting in a total cumulative ascent and descent of over 600 meters.
The section known as 'l'Escalier des Templiers' consists of over 200 steep, carved rock steps.
The path traverses the heart of the Verdon Regional Natural Park, a protected area for griffon vultures.
The river water within the gorge often exhibits a distinct turquoise color due to micro-particles of limestone suspended in the water.
The Point de Départ du Sentier Blanc-Martel marks the trailhead for the most iconic trek through the Verdon Gorge, France's deepest canyon. This trail follows the Verdon River's course for approximately 14 kilometers, connecting the Chalet de la Maline to the Point Sublime. The route features dramatic limestone cliffs and the famous tunnels of the Trescaire and Baou, which require a flashlight for passage. Hikers navigate a landscape of sheer drop-offs and river-level pathways carved into the rock face. The terrain is demanding, characterized by significant elevation changes and long distances. Visitors encounter a variety of geological features, including narrow gorges and exposed rock sections. The trail is one-way for most hikers, requiring logistical planning for transport between the start and end points. It provides direct access to the riverbank at certain stretches of the gorge.
