Should be in good aerobic shape and comfortable with long off‑road rides and sustained climbs; e‑assist reduces but does not eliminate effort.
Ride from Marseille across forest tracks into the white limestone teeth of Calanques National Park, finishing with a swim and lunch in Cassis. Expect a long, scenic day on an electric mountain bike with steep views, hidden coves and practical choices about water, timing and footwear.
You push away from the Avia gas station in northern Marseille and the city’s flat sprawl gives way to a hard, fragrant wind of pine and resin. The track climbs quickly—DFCI forest roads wide enough for a truck but wild enough to feel like a secret—as the electric motor hums under your hands and the Mediterranean stretches into a blue line on the horizon. By midmorning the limestone ridges of the Calanques have stepped into view: white cliffs, serrated and raw, daring you to get closer.

Carry at least 2 liters in a hydration pack and refill in Cassis—there are few reliable taps on the route.
Begin in the cool morning to avoid afternoon heat, crowds, and fire‑risk closures in summer.
Wear sturdy, closed‑toe mountain‑bike shoes with good traction for loose limestone and gravel descents.
Stay on DFCI routes and signed trails—off‑trail riding damages fragile maquis and increases erosion and fire risk.
The Calanques were shaped by karstic limestone processes and human use from shepherding to small quarries; the area became France’s first maritime‑terrestrial national park in 2012.
The maquis is extremely fire‑sensitive—stay on marked tracks, avoid smoking and fires, and follow local guidelines to minimize impact.
Keeps water accessible and balances load for technical sections.
