A lot of people planning a Kotor boat tour search for the same four things at once: the Blue Cave, Mamula Island, Our Lady of the Rocks, and the old Cold-War submarine tunnel. It's a reasonable thing to wonder about, because most operator websites list these as separate highlights scattered across different tours — it's not always obvious that one single trip actually stops at all four. We get this question at the dock more than almost any other: "does one tour do everything, or do we need to book two?"
Short answer: yes, one tour does. Here's exactly which one, what it costs in 2026, how long it takes, and the private-charter version if you'd rather not share the boat.
All Four Landmarks, One Tour — 2026 at a Glance
The one tour that actually covers all four
Out of our full lineup, the 3-hour Bay of Kotor & Blue Cave Adventure is the only shared tour built to hit every one of the four landmarks people search for in a single trip. It leaves Park Slobode in Kotor and runs the outer-bay route: first a stop at the island church of Our Lady of the Rocks, then past the ex-Yugoslav Navy submarine tunnels cut into the cliffs near Mrkov Nos, on to the fortress at Mamula Island, and finally a 20-minute swim stop inside the Blue Cave on the Luštica Peninsula before heading back to Kotor.
It's rated 4.8/5 on TripAdvisor from more than 2,800 reviews and has picked up nine consecutive Travellers' Choice awards (2017–2025), which tells you it's not a rushed, box-ticking route — it's the tour we run daily specifically because it fits all four stops into three hours without feeling like a sprint.
What you actually see at each stop
- Our Lady of the Rocks — a 20-minute visit to the artificial islet's baroque church, built from centuries of sailors dropping rocks at the same spot. Full story in our Our Lady of the Rocks guide.
- The submarine tunnel — a slow pass by the entrance to the Cold-War-era Yugoslav Navy submarine base cut into the cliffs, one of the odder pieces of the bay's 20th-century history.
- Mamula Island — a photo stop at the Austro-Hungarian fortress guarding the mouth of the bay, later a WWII prison camp and now a private hotel. Background in our Mamula Island guide.
- The Blue Cave — the main event: a 20-minute swim stop in the glowing turquoise water of the sea cave on the Luštica Peninsula, best between 09:00 and 12:00 when the light angle is strongest.
See all four in one 3-hour trip
Our Lady of the Rocks, the submarine tunnel, Mamula Island and the Blue Cave — one departure, from €49.99 per adult.
Shared vs private: same four stops, different boat
If you'd rather not share the boat with other passengers, the private Blue Cave Adventure 3h runs the identical four-stop route — Our Lady of the Rocks, submarine tunnel, Mamula Island, Blue Cave — on a boat reserved just for your group, up to 9 guests, from €288 total. For a group of four or more, that often works out close to shared pricing per person while giving you full control of timing and photo stops, which matters most at the Blue Cave when other boats are queuing for the same swim window.
Want the same four landmarks plus a proper beach stop? The 6-hour Blue Cave & Beach Transfer adds Zanjice Beach on the Luštica Peninsula onto the same route, from €72 per adult — the better pick if half a day at anchor matters more to your trip than getting back to Kotor by lunch.
Want the boat to yourselves?
Same four stops — Our Lady of the Rocks, submarine tunnel, Mamula Island, Blue Cave — on a private charter for up to 9 guests.
What's included, and what to bring
Both versions include fuel, water, insurance, all fees and taxes, a licensed English-speaking skipper-guide, life jackets in every size, boat shade, music, swimming stairs and raincoats. Not included: soft drinks and alcohol on board (available to buy before departure), any optional add-on stops, and the entry ticket for the Our Lady of the Rocks museum if you want to go inside — it's a small fee paid on the island itself.
- Swimsuit under your clothes — there's no changing room on board.
- Towel and a few euros in cash for the Our Lady of the Rocks museum entry, if you want to see inside.
- Sunscreen and a hat, though skip anything wide-brimmed that will blow off at speed.
- A charged phone or camera — the Blue Cave's turquoise glow and the fortress silhouette at Mamula are the two shots everyone leaves with.
Captain's Tip
Book the 09:00 or 12:00 departure if the Blue Cave photos matter to you. Sunlight needs to hit the water at the right angle to get the full turquoise glow inside the cave — by the 18:00 slot the light has moved past its best angle for that particular stop.
How this fits with the rest of your Kotor visit
If you're a cruise passenger with a shorter window ashore, our Kotor cruise port guide covers how dock-vs-tender timing affects which tour length actually fits your call. If you're comparing every departure time and price across our full fleet rather than just this one route, the complete 2026 Kotor boat tour guide has the full schedule.
Want a swim stop added too?
Same four landmarks plus Zanjice Beach on a longer 6-hour route — from €72 per adult.
