The Cosquer Cave, located within the park, contains prehistoric cave paintings dating back to between 27,000 and 19,000 years ago, accessible only by a submerged entrance.
The limestone forming the cliffs originated from marine sediments deposited during the Urgonian period approximately 115 million years ago.
The park's marine zone includes the 'Grand Canyon of the Mediterranean,' an underwater canyon reaching depths of over 2,000 meters near the coast.
Traditional dry-stone 'restanques' are visible throughout the park, remnants of ancient agricultural terracing used for olive and grape cultivation.
During the 19th and early 20th centuries, several calanques housed industrial factories, the ruins of which can still be found in areas like Les Goudes.
Parc national des Calanques is a protected area spanning 85 square kilometers of land and 435 square kilometers of sea between Marseille, Cassis, and La Ciotat. The landscape is defined by deep, steep-sided valleys carved into limestone cliffs that drop directly into the Mediterranean Sea. It is the only national park in Europe to encompass terrestrial, marine, and peri-urban environments simultaneously. The park hosts over 140 protected animal and plant species, including the Bonelli's eagle and the endemic Centaurea corymbosa. Access to specific popular calanques, such as Sugiton, is regulated by a reservation system during peak summer months to mitigate soil erosion and environmental impact. The terrain is characterized by Mediterranean scrubland (garrigue) and minimal natural shade. Hiking trails connect the various coves, though many require steep descents and significant physical exertion. The park is managed by the Établissement public du Parc national des Calanques, which enforces strict regulations regarding fire prevention and waste management.

Bring at least two liters of water per person, as there are no natural springs or potable water sources within the park boundaries.
Wear sturdy, closed-toe hiking shoes with high-traction soles; the limestone rock is notoriously slippery and sharp.
Check the official 'Calanques' app or website daily during summer for real-time fire risk closures, which can shut down trail access at short notice.
Attempting to visit during the hottest hours of the day (midday) or wearing flip-flops/sandals for hiking trails.
Access to certain trails and coves may be restricted or require mandatory online booking during summer months; trails may close entirely on high-wind days due to forest fire risk.
Strict no-smoking policy due to high fire risk; leave no trace; drones are prohibited; stay on marked trails to protect sensitive flora.
