Europe's beautiful coastal walk between 2 major cities with breathtaking views

When it comes to scenic hiking trails, Europe offers endless variety - from the alpine peaks of Switzerland to the rugged coasts of the Mediterranean. But nestled between two French gems, Marseille and Cassis, lies one of the continent's most stunning coastal walks.

France may be best known for romantic strolls in Paris or sun-soaked holidays along the Riviera, but its southern coast is also home to the Calanques - dramatic, fjord-like limestone formations that have become a magnet for hikers, climbers, cavers, and day-trippers alike. Stretching from Marseille to Cassis, these towering white cliffs contrast strikingly with the turquoise waters below.

Its main hiking trail, The Sentier du Petit Prince, sits on the Bestouan peninsula and was named in honour of The Little Prince, the world's most-translated book after the Bible. This family-friendly trail offers not just panoramic sea views, but a glimpse into the wild, rocky heart of southern France.

At just over 3.4 km long with a mild elevation gain of 37 metres, the trail is accessible to hikers of all levels and makes for an ideal half-day adventure. It begins at the edge of Port-Miou, a narrow calanque-turned-marina that serves as a quiet launching point with ample parking.

Early in the walk, you'll find a small information post (CQ-111) offering historical and ecological facts about the region. At the 1.08 km mark, you'll pass the Exsurgence de Port-Miou, a natural spring that adds a refreshing touch to the route.

Soon after, at around 1.46 km, hikers reach the beach at Plage de Port Pin, a popular stop for sunbathers and swimmers nestled in a scenic cove. Though slightly off the main path, the detour to Calanque de Port-Pin (1.71 km) is worth the effort, offering a postcard-perfect lookout point over the Mediterranean.

Several viewpoints along the way provide ideal photo opportunities - or just a quiet moment to sit and admire nature's handiwork.

If you're tempted to visit, spring and early autumn - specifically April to June or September to October - are the best times for hiking the trail.

The summer season poses a significant fire risk, and parts of the Calanques National Park are often closed to visitors during July and August.

And keep in mind that, despite the short length of the Sentier du Petit Prince, it's important to come prepared. Wear sturdy shoes, as parts of the trail are rocky, slippery, and exposed to high winds. The infamous Mistral, a strong, cold wind common in Provence, can make even the most peaceful path feel intense.

There are no shops or restaurants on the trail, so be sure to bring plenty of water, snacks, and sun protection. And while it may be tempting, camping is strictly prohibited within the protected Calanques.

For those who want to explore further, it's possible to walk the entire coastal stretch from Cassis to Marseille, following the red and white trail markers.

This route takes 10 to 12 hours and passes through the other two major calanques: En Vau, with its dramatic cliffs and sapphire waters, and Sugiton, a favourite among local swimmers and climbers.
