Where the limestone giants of Provence tumble into the cerulean Mediterranean, Marseille's Calanques National Park unfolds like a geological sonnet.

From the chalk-white cliffs of Sugiton to the prehistoric caves of Morgiou, this UNESCO-listed wonder offers hikers, swimmers and sailors a dazzling natural playground just minutes from France's oldest city.

Geological Wonders

Formed over 120 million years, the calanques' Jurassic limestone reveals fossilized sea creatures in its stratified cliffs. The park protects 900 plant species, including the rare Marseille cinquefoil, while peregrine falcons nest in 400-meter-high sea cliffs. Summer transforms the rock into a luminous white beacon visible from space.
