Sea trip to the Frioul islands and the Château d'If

Looking out over the horizon from Marseille, you can't miss the four limestone islands that stand out against the Mediterranean: these are the Frioul Islands. If, Pomègues, Ratonneau and Tiboulen enjoy an arid climate, making them home to a rare and sometimes endemic flora that is particularly popular with hikers. People also come here for its creeks, with their clear waters spared from the crowds. It's also a favourite nesting place for gulls, which can become violent if they feel their nests are in danger, so keep an eye out! On the Ile d'If, the famous Château d'If, a former prison made famous by Alexandre Dumas in his novel The Count of Monte Cristo, faces the town. The only way to get to the Frioul islands is by sea, so take a short cruise in the bay of Marseille. The island of Château d'If and the Frioul islands are part of the Calanques National Park.

The history of the islands of Frioul and the Château d'If

The Frioul islands have been occupied since Neolithic times, but by the 17th century they had become one of the largest sanitary complexes in the Mediterranean. Located right at the entrance to the port of Marseille, the crews of ships likely to be carriers of contagious diseases - such as the plague or cholera - were quarantined there to protect the inhabitants of the city.

Because of their ideal location, the Frioul islands were also central to the city's military strategy. As early as the 16th century, a fort crowned the island of Ratonneau, then it was the turn of the island of If to be fortified before Louis XIV extended these military constructions to the entire archipelago. The last military building on the Frioul islands was erected in 1902. Many military and sanitary remains can still be found on the Frioul islands.

Why visit the Frioul islands and the Château d'If?

Situated six kilometres off the coast of Marseille, the Frioul islands offer a change of scenery and a great way to get away from it all, just a few minutes away by boat. Maritime shuttles drop travellers off on the island of Ratonneau, which is linked to the island of Pomègues by a footbridge. Covering almost 200 hectares, the Frioul archipelago is criss-crossed by hiking trails offering breathtaking views of Marseille and the Mediterranean Sea.

The islands are inhabited, so you can also stroll around the picturesque port of Frioul and have lunch facing the sea in one of the archipelago's fifteen restaurants. Finally, as the Frioul islands are only accessible by boat, the small coves and beaches are spared from mass tourism, making them perhaps the most pleasant coves in the National Park!

The If island is more of an islet than an island in the strict sense of the word. This isolated and unique landscape is the pride of the Frioul archipelago. If is best known for its majestic castle, built on the orders of King François I at the beginning of the 16th century to deter maritime attacks on Marseille. It worked so well that it was never attacked! A few years after its construction, the Château d'If became a prison from which, it was said, there was no escape. The fortress owes its fame toAlexandre Dumas' famous novel, The Count of Monte Cristo.
