Where to stay

Marseille offers a range of stays from historic 'fishermen's houses' in the Vallon des Auffes to high-end boutique hotels on the harbor near the Vieux-Port. Budget-conscious swimmers often look for apartments in the 7th arrondissement, while those seeking comfort opt for the seaside properties along the Corniche. Expect to pay between €120 and €250 per night during the June race period, though prices fluctuate based on proximity to the water.

Things to do nearby

The weekend is ideal for exploring the limestone cliffs of the Calanques via kayak or SUP, providing a perspective of the coast similar to that of the marathon swimmers. Visitors can book guided tours of the submerged prehistoric caves or participate in local pastis-tasting sessions in the historic Panier district. For those interested in archaeology, the Roman Docks Museum offers context on the city’s ancient trade routes, while the hiking trails winding toward the massif of Puget offer panoramic views of the entire race course.
