Two islands, a short crossing, two different moods
The Lérins Islands sit just off Cannes, reached by a 15 to 20 minute boat crossing from the old port. Once you step off the boat, the coast recedes fast — no cars, no beach clubs, no Croisette crowds. What replaces it are pine-shaded paths, a 17th-century fort, and, on the second island, an active abbey where monks still make wine. The two islands are close enough to combine in a single day, but they are not the same trip. Sainte-Marguerite is the walking-and-history island; Saint-Honorat is the quieter, more contemplative one. Knowing which one matches your afternoon — or whether to do both — is the main decision to make before you buy a ferry ticket.
This page covers the islands themselves: what there is to see, how the two compare, and how long each visit realistically takes. For the town of Cannes — the Croisette, the Palais des Festivals, the Suquet old town — see the separate Cannes guide.
Sainte-Marguerite: the Fort Royal and the pinewoods
Sainte-Marguerite is the larger and busier of the two islands, and the one most people mean when they say they’re “doing the Lérins Islands” for an afternoon. The boat lands near the Fort Royal, a fortress built under Vauban’s era of coastal defence and later used as a state prison. Inside, the cell shown as that of the so-called Man in the Iron Mask draws most of the curiosity — the real identity of the prisoner held here in the late 17th century is still debated by historians, and the site presents it as an open question rather than a solved mystery. The fort also houses the Musée de la Mer, with exhibits on the island’s military and maritime history.
Beyond the fort, the island is mostly pine forest, criss-crossed by shaded paths that make for an easy, flat walk. A loop around the perimeter takes roughly an hour and a half at an unhurried pace, with clearings that open onto views back toward the Esterel and across to Saint-Honorat. There’s little in the way of formal amenities — a couple of small snack points near the landing, nothing more — so this is not an island for a leisurely restaurant lunch. Pack water, especially in July and August when the pine cover still doesn’t fully offset the midday heat.
Sainte-Marguerite works well as a half-day trip: boat over, an hour or so at the fort and museum, a walk through the woods, boat back. It’s also the easier of the two islands for families, since the paths are level and the fort has enough to hold a child’s attention for a while.
a catamaran crossing to the Lérins Islands is one straightforward way to reach Sainte-Marguerite without working out ferry schedules yourself.
Saint-Honorat: the abbey and the vineyards
Saint-Honorat is smaller, less visited, and noticeably quieter than its neighbour. The island has belonged to a community of Cistercian monks for centuries, and it still does — the abbey buildings are active, not a museum piece. Visitors can walk the island’s perimeter path past the ruins of an older fortified monastery on the southern tip, through vineyards that the monks farm and bottle themselves, and along a coastline with almost none of the built-up feel of Sainte-Marguerite.
There’s no fort to visit here, no equivalent of the Iron Mask story — the appeal is the contrast itself: a working monastic community on an island a short crossing from one of the Riviera’s busiest resort towns. Visitors are asked to keep a respectful volume near the abbey buildings, and some areas closest to the monks’ living quarters are off-limits to the public. The wine the monks produce (still and sparkling, along with a herbal liqueur) can be bought at a small shop near the landing, and it’s one of the few genuinely distinctive souvenirs on this stretch of coast.
A visit to Saint-Honorat alone, walked at an easy pace with a stop at the shop, takes two to three hours plus the crossing. It suits travellers who want something closer to a quiet nature walk than a sightseeing stop, and it’s a reasonable choice if you’ve already spent a morning in busy Cannes and want the afternoon to slow down.
Doing both islands in one day
Sainte-Marguerite and Saint-Honorat are connected by boat as well as each being reached from Cannes, so combining them is possible without returning to the mainland in between — though this guide won’t state specific shuttle times, since they vary by season and operator. As a rule of thumb, allow the whole day: morning crossing to one island, a few hours there, a shorter inter-island hop, a few hours on the second, then the return to Cannes before the last boats of the day. Rushing both islands into a half-day is possible only if you cut Sainte-Marguerite down to the fort alone and skip the woodland loop, which defeats much of the point of going.
If choosing just one, the decision comes down to what you want from the afternoon. Sainte-Marguerite gives you more to look at — the fort, the museum, a real story attached to a real cell — plus flatter, easier walking. Saint-Honorat gives you quiet, a genuine sense of remove from the coast, and the wine. Neither is the “better” island; they answer different moods.
| Sainte-Marguerite | Saint-Honorat | |
|---|---|---|
| Main draw | Fort Royal, Man in the Iron Mask cell, museum | Working abbey, monks’ vineyards and wine |
| Atmosphere | Wooded, walkable, moderately busy | Quiet, contemplative, fewer visitors |
| Typical visit | 2–3 hours | 2–3 hours |
| Walking | Flat perimeter loop, about 90 minutes | Flat perimeter path past vineyards |
| Food and drink | A couple of small snack points | Small shop selling abbey wine and liqueur |
| Good for | Families, first-time visitors, history | Travellers wanting quiet, wine, nature |
Getting there from Cannes
Boats to both islands leave from the old port area of Cannes, a short walk from La Croisette. Several operators run the crossing, and departures are frequent enough in the warmer months that you generally don’t need to plan far in advance — though buying tickets the same morning is safer than assuming you can just walk on, especially in July and August. The crossing itself takes 15 to 20 minutes each way, calm enough on most days that seasickness isn’t a serious concern, though the open stretch can get choppy when the mistral or a strong easterly is blowing.
Coming from Nice, the simplest approach is the coastal train to Cannes — see the day trip from Nice guide for timing — followed by the short walk to the port. There is no direct boat from Nice to the islands; Cannes is the departure point.
a private boat trip to the Lérins Islands is worth considering if you’d rather set your own schedule between the two islands instead of working around a shared ferry timetable, and it also suits a small group that wants the crossing itself to be part of the day rather than just transport.
When to go
The islands are open to visitors year-round, but the experience changes a lot with the season. From May to September, ferry frequency is at its highest, the pinewoods on Sainte-Marguerite offer genuine relief from the heat, and the sea is calm enough for a smooth crossing most days. July and August bring the most visitors — Sainte-Marguerite in particular can feel busy around the fort in the early afternoon — while Saint-Honorat stays noticeably calmer even at the height of summer, since its appeal draws a different kind of visitor.
Outside the main season, from October to April, crossings run less often and some services on the islands scale back, but the upside is near-empty paths and a much quieter Fort Royal. Winter storms can cancel crossings altogether for a day or two at a time, so this isn’t a trip to build a tight schedule around outside of summer. Spring and early autumn — May, June, September — tend to offer the best trade-off: reliable boats, manageable crowds, and comfortable walking weather.
a private boat tour to the Lérins Islands departing from Mandelieu is a useful alternative for travellers already based further west along the coast, closer to the Esterel, rather than in Cannes itself.
What to bring and what to expect
Neither island has much shelter from the sun once you’re away from the pine cover, so sunscreen and a hat matter even for a short visit, and comfortable shoes make the walking paths — mostly packed earth and gravel, not paved — much more pleasant. Bring water, particularly for Sainte-Marguerite’s full perimeter loop, since the snack points near the landing are the only source once you’re on the trail. Cash is worth carrying for the wine shop on Saint-Honorat and any small purchases on Sainte-Marguerite, though card payment is increasingly common.
Neither island suits a swimming-and-beach day the way the mainland coast does. There are a few small coves where people do swim, informally, but this isn’t the destination for it — the beaches around Cannes and further along the coast toward Antibes are the better choice for that. Come to the Lérins Islands for the walk, the fort, and the abbey, and treat any swimming as a bonus rather than the point.
Nearby stops worth combining
Because the crossing runs from Cannes, most visitors fold the islands into a longer day that also touches the town itself, or pair it with a broader look at the western Riviera. Travellers building a two-day itinerary around this stretch of coast might look at the dedicated Cannes, Antibes and the Lérins Islands itinerary, which sequences the islands alongside Antibes old town and the Picasso museum. For those coming specifically for boat trips rather than sightseeing, the Lérins Islands ferries and boat trips guide covers the practicalities of departures and operators in more depth, and the wider Cannes boat tours and yacht cruises guide lists other options departing from the same port.
a full-day French Riviera panorama tour is one way to see the islands as part of a broader look at the coast if you’re short on time and want the Lérins crossing bundled with other stops rather than arranged separately.
Lérins Islands: frequently asked questions
Can you visit both Sainte-Marguerite and Saint-Honorat in one day?
Yes, but it takes a full day rather than a half-day. Allow time for the crossing from Cannes, a few hours on each island, and the boat between the two, plus a margin before the last return crossing of the day.
Which island is better for families?
Sainte-Marguerite, generally. Its paths are flat and easy, the Fort Royal and its Man in the Iron Mask cell give children something concrete to look at, and the walk through the pinewoods is short enough not to tire younger visitors.
Is there a beach on the Lérins Islands?
Not in the way the mainland coast has beaches. There are a few small, informal coves where people swim, but neither island is set up as a beach destination — come for the fort, the walking, and the abbey rather than for swimming.
How long is the boat crossing from Cannes?
About 15 to 20 minutes each way, from the old port near La Croisette. The sea is calm on most days, though it can get choppier when a strong wind is blowing.
Can you buy wine on Saint-Honorat?
Yes. The monks on Saint-Honorat produce still and sparkling wine as well as a herbal liqueur, sold at a small shop near the landing. It’s one of the more distinctive souvenirs available on this part of the coast.
Is the Man in the Iron Mask story true?
The Fort Royal on Sainte-Marguerite did hold a prisoner in the late 17th century whose identity was concealed, and this cell is presented as the likely site of his imprisonment. Historians still debate who he actually was, and the fort’s exhibit treats it as an open question rather than a settled fact.
Do you need to book ferry tickets in advance?
It isn’t usually essential outside peak summer weeks, since crossings run frequently through the season, but buying tickets the same morning rather than assuming a same-day spot is the safer approach in July and August.
Is Saint-Honorat open to visitors, given that monks live there?
Yes, the public paths and the wine shop are open to visitors, though some areas near the monks’ living quarters are off-limits and visitors are asked to keep noise down close to the abbey buildings.
