On the water · Verified: 30 July 2026
A boat is the only way most visitors will ever see En-Vau, and the one calanques product that survives a red fire day. But every commercial boat here is a look-don't-land product, the biggest Marseille operator won't sell you a ticket more than 48 hours out, and the wind that cancels Cassis isn't the one you think. Every fare below was read off the operators' own price pages on 30 July 2026.
One operator runs the whole Cassis port: the GIE des Bateliers Cassidains — 12 historic shipowning families, 15 boats from 12 to 75 seats, five of them diesel-electric hybrids, all flying the park's blue Esprit Parc national label. The ticket office is on the quai Saint Pierre, behind the square Gilbert Savon, open seven days a week subject to weather. The circuits nest — each longer one contains the previous route.

| Circuit | Time | 2026 fare | What it adds |
|---|---|---|---|
| 3 calanques | 1h00 | €21 | Port-Miou, Port-Pin and En-Vau — the postcard three |
| 5 calanques | 1h20 | €25 | + L'Oule and Devenson, past the Castelviel cliffs — the most spectacular stretch |
| 8 calanques | 1h50 | €29 | + L'Œil de Verre, Pierres Tombées, Sugiton, Morgiou |
| 9 calanques | 2h20 | €33 | + Sormiou — the full run, with a lot of open-water transit |
| 3 calanques + arrêt détente | 2h00 | €40 flat | The ONE Cassis product with a swim — see below |
Two things the fare table doesn't tell you. First: every one of the four standard circuits is commentary-only — no stop, no swim, no landing, at any price. Second: the widely republished "€19 Cassis boat trip" is a stale price; 2026 starts at €21. The booking system carries Adults / Children / Babies categories, so reduced fares exist, but the operator doesn't publish the child rates — ask at the kiosk.
The "3 calanques + arrêt détente" (€40, adult and child alike, four departures daily at 09:15 / 12:00 / 14:00 / 16:00) runs on the 12-seat boats — a hard cap of 12 passengers. The swim happens in the open sea at anchor off the En-Vau sector: a ladder or a jump into deep water, no beach, no shallows, no lifeguard, nothing to stand on. The operator restricts it to declared swimmers, which is doing real work in that sentence. If you wouldn't happily swim 50 m in deep water away from a boat, this is not the easy add-on it looks like — the honest alternative for actually standing on a calanque beach is a kayak from Cassis or walking in.
Which circuit? For most people the 5-calanque at €25: it covers the postcard three plus the Castelviel–Devenson wall, the best cliff scenery on the coast, without the hour of open-water transit the 8- and 9-calanque runs add. With under-10s, sun-sensitivity or a weak stomach, take the €21 hour.
Two distinct operators work the Vieux-Port, and people book the wrong quay constantly. Croisières Marseille Calanques (CMC) sells and boards at the north-east corner of the harbour — angle Quai du Port / Quai des Belges, facing the brasserie La Samaritaine, five minutes from the Vieux-Port metro. Icard Maritime is at 1 Quai Marcel Pagnol on the opposite (Rive Neuve) side, 10–15 minutes' walk around the harbour head. Marseille circuits run eastward: the 2–2h30 Essentiel covers Callelongue, the Riou archipelago, Sormiou, the Cosquer cape, Morgiou and Sugiton; only the 3h15 Intégrale continues to En-Vau, Port-Pin, Port-Miou and the bay of Cassis.
| Circuit | Adult | Child 4–12 | Family pack |
|---|---|---|---|
| Intégrale (3h15) — 09:30 / 14:00 / 15:30 | €35 | €27 | €109 |
| Essentiel (2h–2h30) — 4 daily departures | €30 | €25 | €99 |
| Baignade swim circuit (3h–3h30, Jul–Aug only) | €45 | flat — and under-10s refused | |
| Château d'If (45 min) | €14 | flat; excludes monument admission | |
The family packs are real but modest savings: €109 versus €124 for 2+2 bought separately on the Intégrale, €99 versus €110 on the Essentiel. Under-4s travel free but must hold a ticket or boarding is refused.
Icard's Intégrale (3h15, Marseille→Cassis) prices at €33 adult / €25 for 4–11 / €29 for 12–17 (same rate for students and French AAH disability-allowance holders) / under-4 free / €100 family (2+2). Its July–August swim circuit is €40 flat, its Château d'If run €11. A ticket is required on board from age 1, even for free children. Commentary is advertised in French, English, Spanish, Italian, Russian and Mandarin — the most multilingual boat on the coast.
The booking inversion nobody explains: CMC — the biggest Marseille operator — opens reservations only 24 to 48 hours before departure, weather-dependent, and states its circuits are not sold online. You cannot book CMC weeks ahead; it's a kiosk-or-phone decision (04 91 58 50 58) made 1–2 days out. Meanwhile third-party platforms sell boat experiences on this same water months in advance with free cancellation. Where a platform's promise and an operator's own rule disagree, the operator's rule decides what actually sails.
A fourth port most guides omit: La Ciotat, ten minutes by train beyond Cassis, where Les Amis des Calanques run west beneath the 394 m Soubeyranes cliffs — the only way to feel Cap Canaille from below — for €18–€34 (under-12s €6 off). The catch: a minimum of 15 passengers to sail at all, which quietly cancels shoulder-season weekday departures.
"The mistral is blowing, so the boats won't run" is bad advice at Cassis — and good advice at Marseille. The two ports cancel on different winds, and knowing which is which rescues days.
The operator's published rule: excursions are cancelled for strong East/South-East or South/South-West winds with swell, and only modified or cancelled for a strong mistral. The Cassis coast sits in the mistral's lee — the NW wind blows offshore there and flattens the water under the cliffs, while an easterly swell hits the coves head-on. Day-of schedule and forecast go up on the operator's Facebook and Instagram; they point visitors at Windguru, Météo-France and the Cassis webcam.
The runs south past Cap Croisette and east toward Cassis cross open water with a long north-west fetch, so a strong mistral genuinely cancels or curtails Vieux-Port departures (and the Frioul ferries with them). A 40 km/h mistral can mean a flat, brilliant, half-empty day on a Cassis boat and a refund queue in Marseille — and a 20 km/h easterly with a metre of swell can do the reverse. Check the wind direction, not just the speed.
The seasonal shape works in your favour: by Météo-France normals, August is the calmest month of the year on this coast (February–April the windiest) — so cancellations are rarest exactly when most people visit. One caveat from the closures system: mistral days are often the days fire risk closes the trails, so the flattest water tends to sit under the most-closed massif. That is an argument for the boat, not against it.
The sequencing rule that beats any forecast: boats are weather-contingent, indoor attractions are not. Book the boat first, and keep the Cosquer cave replica or the Cassis wine cellars as the pivot for a blown-out day.
The kiosk circuits are the best raw sightseeing value in the park — nothing on any platform shows you En-Vau's cliffs for €21. But they are one specific product: a seat on an open deck for one to three hours, commentary, no stop. The marketplace boat experiences and catamaran and sailing trips sell a different product — half or full days on the water, guaranteed swim stops, small groups, often food — and for three kinds of visitor the higher price is the honest buy:
Two honesty notes that apply to every platform listing. Marketplace boats obey exactly the same law as the kiosk ones: no landing, anywhere, ever — a "swim stop at En-Vau" means open water near En-Vau, not the beach. And bookable-months-ahead with free cancellation is itself the feature CMC cannot offer: for cruise passengers and fixed itineraries, the platform's calendar — not the boat — is what you're paying the margin for.
One check that costs nothing: legal tour boats in the park core fly an orange pennant with an orange hull sticker. The park's warning is aimed at you, not the operator — absence of the signage marks an illegal service and exposes the passenger to prosecution. Look before you board.
Skippering yourself is the one way to stop where you like, swim off the hull and stay two hours in an empty cove — and it is the most heavily regulated visitor activity in the park. The regulation is aimed at you as much as the operator.
The legal shortcut past all of it — the vignette homework, the anchoring map, the wind judgement — is a skippered charter: a professional drives, you swim, and the boat goes everywhere a private one legally may. The private skippered sailing charter from Marseille (★5.0, 121 reviews, about $975 for the whole group) is that product — per head, for six people, it lands near the cost of a rented bareboat without the liability. Remember the one thing no format buys: a landing on a famous beach. The rules bind your rented boat and the 75-seat vedette alike — if standing on sand is the goal, it's the kayak or the trail.
From June to September, a red fire-risk day closes every trail, crag and calanque road in the rated massif — and changes nothing about a boat tour. The fire arêté regulates access to forest massifs; the sea isn't one. Navigation, anchoring and swimming from the boat all stay legal, which is why the operators keep sailing and why the boat is the one calanques plan that cannot be closure-cancelled.
The flip side is absolute: the closure covers arrival "y compris par la mer" — including by sea. Stepping onto a rock, beaching a tender or swimming ashore from an anchored boat is the same €135-per-person offence as walking past the barrier. On a red day you can be legally afloat twenty metres from a beach you are legally forbidden to touch. Since no commercial boat may land you on any day, the tour you booked loses precisely nothing — and the Frioul archipelago, which is not a rated massif, stays open as the day's other loophole.
Cassis for the white-cliff calanques: En-Vau is 10–15 minutes out, the shortest circuit is €21, and you buy on the day. Marseille for the 20 km of Marseille-side coast, Riou and the Cosquer cape — but only its 3h15 Intégrale reaches the white cliffs at all. Different coastlines, different prices, different cancellation weather.
No — commercial landing is banned along the entire park coast, every day, and the Cassis operator says so itself: no drop-offs; to reach beaches like En-Vau you must walk. No water taxi exists or can exist. Walk in, or take a kayak from Cassis with one of the three authorised renters (1 May–30 September).
Only the dedicated summer swim products — Cassis €40 (max 12, four daily departures), Icard €40 and CMC €45 (both July–August, under-10s refused). Every standard circuit is commentary-only: no stop, no swim, no landing. All swims are off the anchored boat in deep open water — details on the swimming page.
Cassis: not at all — kiosk, same day (pay 30 minutes before departure even if you reserved online). CMC: you can't book more than 24–48 hours out, offline only. Platforms: months ahead with free cancellation — the right tool for cruise passengers and fixed dates. Far-ahead booking only genuinely matters for charters and groups of 12–20+.
No. Red days close land access; navigation stays legal and the boats sail. Since no boat lands passengers anyway, your product is unchanged — it becomes the day's best option, with Frioul and the Cosquer replica as the backups.
At Cassis: strong E/SE or S/SW wind with swell (the mistral only modifies — Cassis sits in its lee). At Marseille: the mistral, which hits the exposed crossings. Check direction, not just speed; August is the calmest month by Météo-France normals. Day-of answers live on the Cassis operator's social feeds.
Not on any Cassis boat — the operator says so plainly. Free toilets by the ticket office, paid ones on the beach promenade one minute away. Go before a 2h20 circuit. The bigger Marseille vessels don't publish provision either; assume minimal.
Cassis: live French plus a QR-code audio guide in English, Spanish, Portuguese, Japanese and German — bring earbuds or you get French only. Icard advertises six languages including English. CMC doesn't publish its languages. On marketplace boats, check each listing.
Yes, at or under 6 hp / 4.5 kW — and realistically only from Cassis; Marseille's no-licence fleets at L'Estaque can't reach the park and back. Only rent where you see the park's green vignette on the hull: its absence exposes you to prosecution. No anchoring at En-Vau/Port-Pin, no anchoring on seagrass, 5 knots in the 300 m band.
