Îles de Lérins: The Complete Guide to Visiting from Cannes

Why the Lérins Islands Deserve a Day of Your Cannes Trip

The Lérins Islands are part of the commune of Cannes, yet they feel removed from it in every meaningful way. Where La Croisette is about being seen, the islands are about disappearing into Aleppo pine forest, swimming off rocks with almost no one around, and standing inside a 17th-century fortress where the Man in the Iron Mask was once imprisoned.

The two main islands — Sainte-Marguerite and Saint-Honorat — are only about 1 km apart, but they attract very different visitors. Sainte-Marguerite is the larger, more accessible island and works well for families, hikers, and anyone after a beach day away from the crowds. Saint-Honorat is smaller, protected, and owned by the Lérins Abbey, a functioning Cistercian monastery that has operated there since the 5th century. Both are genuinely worth visiting, and the logistics are simpler than most guides make them sound.

Ferry Operators, Schedules, and Fares

All ferries to the Lérins Islands depart from the Vieux-Port in Cannes (Quai Laubeuf, also signposted as the Old Port). The crossing takes roughly 15–20 minutes. There are multiple operators, and the key practical detail is that they serve different islands.

• Riviera Lines Serves Sainte-Marguerite. Multiple daily departures including 07:30, 09:00, 10:00, 11:00, 12:00, 13:00, 14:00, 15:00, 16:00, and 16:30. Returns from the island run 07:45 to 18:00. Adult return fare: €19; youth/senior: €17.50; child (5–12): €13.50; under 5: free. A 'last trip' discounted fare of €16 is also available.
• Planaria (Cannes-Îles de Lérins) The only operator serving Saint-Honorat. Also serves Sainte-Marguerite. Book directly via their website cannes-ilesdelerins.com. This is the operator to use if Saint-Honorat is your priority.
• Trans Côte d'Azur and other operators Additional companies including Trans Côte d'Azur and SARL Horizon serve Sainte-Marguerite. Fares and timetables vary; Rome2Rio estimates range from €12–€18 for the crossing.

The single most common logistical mistake visitors make: assuming they can take one boat to Sainte-Marguerite and then hop directly to Saint-Honorat. There is no island-to-island ferry. To visit both in one day, you must return to Cannes pier and board the Planaria service separately. It is doable, but plan for a full day and an early start. Most visitors who try to rush both islands end up with too little time on each.

Sainte-Marguerite: What to Do on the Larger Island

Sainte-Marguerite is about 3 km long and 900 metres wide at its widest point, large enough to spend a full day without retracing your steps. The interior is dense pine and eucalyptus forest crossed by walking paths, and the coastline alternates between small sandy coves and rocky shelves that drop cleanly into clear water. The main draw beyond the landscape is the Fort Royal, a star-shaped fortress built in the 17th century that served as a state prison. The most famous prisoner held here was the Man in the Iron Mask, made famous by Alexandre Dumas, though historians still debate the prisoner's true identity.

The Fort Royal now houses the Musée de la Mer (Museum of the Sea), which holds Roman and Saracen artefacts recovered from shipwrecks in the bay. The exhibition is modest in scale but genuinely interesting if you have even a passing curiosity about the maritime history of the Côte d'Azur. Admission is required; verify current prices with the Cannes tourism office before visiting.

For swimming, the northern shore sheltered from the prevailing wind is the better choice in spring. The southern coastline has clearer water but can be choppy. There is a restaurant on the island, but it is seasonal, can get crowded, and is not particularly good value. A better plan is to bring a picnic from the Marché Forville in Cannes before you board.

• Walk the full perimeter trail: roughly 7–8 km, flat, shaded, takes about 2 hours at a relaxed pace
• Fort Royal and Musée de la Mer: allow at least 45–60 minutes including the cells where the Iron Mask prisoner was held
• Swimming off the rocks on the north and east shores: clearest water early morning before other ferry passengers arrive
• Birdwatching: the interior forest is a protected natural area with no development

Saint-Honorat: The Monastery Island

Saint-Honorat is smaller (about 1.5–1.6 km long), quieter, and strictly speaking a private island. The Cistercian monks of Lérins Abbey own the island and have welcomed visitors for centuries, but this is not a beach day destination. There are no public beaches in the way you find on Sainte-Marguerite, and the atmosphere is deliberately contemplative.

What draws visitors here is the abbey itself, with buildings dating from the 11th century, and the 11th-century fortified tower that stands on the southern shore. The tower, surrounded by the sea, is one of the more striking medieval structures on the Riviera. You can walk the island's perimeter path, visit the abbey church (dress modestly), and stop at the monastery shop where the monks sell their own wine. Lérins Abbey produces several AOC wines from vines planted across the island, and the shop is the only place to buy them. Quality is respectable, particularly the whites, and prices are reasonable.

Saint-Honorat is genuinely not for everyone. If you want beaches and activity, stay on Sainte-Marguerite or use the day for something else in Cannes. But if you appreciate the contrast between the Riviera's noise and the island's near-total silence, and you have any interest in medieval history or Cistercian monastic culture, this is one of the more unusual experiences available from any beach resort in France.

Best Time to Visit the Lérins Islands

The islands are accessible year-round, but the experience varies considerably by season. For the full picture of when to time a Cannes trip, the best time to visit Cannes guide covers the seasonal logic in detail. For the islands specifically, May, June, and September hit the sweet spot: warm enough to swim, light enough on visitors to actually enjoy the forests and shorelines.

July and August bring the highest ferry frequency, but also the most visitors. Sainte-Marguerite in particular can feel uncomfortably crowded on peak summer days, with queues at the pier and occupied rocks by mid-morning. The island's size means you can usually find solitude by walking further from the ferry dock, but it requires effort. Winter visits are atmospheric and genuinely quiet, but service reductions on Sundays and the possibility of cancelled sailings due to sea conditions are real constraints.

The Cannes Film Festival in mid-May draws large numbers to the mainland, but curiously has minimal impact on the islands — most festival attendees have no interest in a day hike. This makes the festival period a reasonable time to escape to the islands if you happen to be in Cannes during the event.

Practical Planning: What to Bring and What to Expect

The islands have limited facilities. Sainte-Marguerite has one seasonal restaurant and a small snack bar near the dock, but neither is reliable outside peak season. Saint-Honorat has the monastery shop and a restaurant plus snack bar run in partnership with the abbey, but options remain limited compared with Cannes. Bring water — more than you think you need, especially in summer — and a picnic. The Marché Forville in Cannes, a short walk from the port, is open most mornings and is the obvious place to stock up on supplies before boarding.

Sun protection is more critical than most visitors anticipate. The forest paths are shaded, but the coastal walks and swimming spots are fully exposed, and the Mediterranean sun reflects intensely off the water. Wear sunscreen, bring a hat, and consider a light cover-up for the midday hours.

The ferry is accessible to people with reduced mobility according to the Cannes tourism office. If you are travelling with mobility considerations, contact the specific operator in advance to confirm arrangements. For practical details on getting around Cannes before and after the ferry, the getting around Cannes guide covers transport options from the train station to the port.

• Water: at least 1.5 litres per person for a full day in summer
• Food: picnic from Marché Forville or a Cannes bakery — island food options are limited and pricey
• Footwear: closed shoes or grip sandals for rocky coastal paths; flip-flops work for the main dock area only
• Swimwear: rocks rather than sand predominate on the best swimming spots
• Cash or card: verify payment options with ferry operators; smaller operators may prefer cash

Combining the Islands with a Broader Cannes Itinerary

A day on the Lérins Islands fits naturally into a 2- or 3-day Cannes visit. If you are working out how to structure your time, the 2 days in Cannes itinerary is worth checking — the islands work best as a full day rather than a half-day add-on, particularly if you plan to visit both Sainte-Marguerite and Saint-Honorat.

On the day before or after the islands, the Le Suquet quarter of Cannes offers a direct visual line over the bay to the islands — looking out from the hilltop at Notre-Dame de l'Espérance is an easy way to orient yourself and appreciate the islands' position relative to the coast.
