Kotor Bay boat tours: Perast, Our Lady of the Rocks and beyond

What “a boat tour of the bay” usually means

Ask three operators in Kotor old town for a boat tour and you’ll get versions of the same trip: out of the marina, past Dobrota and Prcanj on the way to Perast, a stop at Our Lady of the Rocks, and back. Some add Risan for its Roman mosaics, some add the Blue Cave near Lustica, and a handful throw in a tube ride for the kids. The bay itself is a ria — a drowned river valley, not a fjord — which is why the water stays calm enough for open speedboats even on days when the open Adriatic is choppy.

The two variables that actually change your day are duration and whether you’re on a shared boat or a private one. Everything else — which stops, how long at each — follows from those two choices.

Half-day loop vs full-day with the Blue Cave

Format	Duration	Typical price, shared group (per person)	Private charter, from
Perast + Our Lady of the Rocks loop	3–4 hours	€25–45	€150–200+ for the boat
Loop + Risan mosaics	4–5 hours	€30–50	€180–250+ for the boat
Full day with the Blue Cave	6–8 hours	€45–70	€250–350+ for the boat
Sunset-only cruise, no landings	2–3 hours	€20–35	—

Private prices are per boat, not per person, which is the detail that changes the maths. Split four ways, a €200 private charter comes to €50 a head — close to the shared-tour price but with your own schedule and no other passengers. Split two ways, it’s a genuine premium.

The half-day loop is the one to book if your time in Kotor is limited to a day or two; it’s also the version that pairs cleanly with an afternoon back in the old town. The full-day version only makes sense if the Blue Cave itself is the draw, since the transit time to reach it roughly doubles the day.

Group speedboat or private charter

a shared speedboat run to Perast and Our Lady of the Rocks is the standard entry point: a fixed departure time, a set route, and a price per seat rather than per boat. It suits solo travellers and couples who don’t want to pay for an entire boat, and it’s the cheapest way to see both stops from the water rather than by road.

If you’d rather set your own pace, stop longer where you like, or skip a crowded landing altogether, a private speedboat charter of the bay gives you that control. It’s worth comparing against the group price per head before booking — for two people it rarely pencils out, for four to six it often does.

Families travelling with children sometimes prefer a Perast speedboat tour that adds a tube ride, which turns the return leg into something closer to a watersports outing than a sightseeing cruise. It’s a reasonable way to keep kids engaged on a longer day, though it isn’t the tour to pick if calm, unhurried photography of Perast and the church is the priority.

For a more history-led version of the same route, a private half-day tour with an archaeologist guide covers the same stops with commentary on the bay’s Venetian-era captains, the 1979 earthquake damage still visible on some Perast facades, and how Our Lady of the Rocks was built up from submerged rock over centuries. It costs more than a standard speedboat tour but suits anyone who wants context rather than just the view.

Anyone trying to fit the bay into a wider first look at the country can also consider a combined Best of Montenegro and Kotor Bay tour, which mixes a bay cruise with a broader overview — useful on a short stopover, less useful if you’re already spending several days in the Bay of Kotor and can do Perast and the mountains as separate outings.

What you actually see at each stop

Perast. A single-street baroque town squeezed between the water and the hillside, with two 17th- and 18th-century churches and a scatter of captains’ palazzos that have seen better days. Most boat tours give 45 minutes to an hour here — enough for the waterfront and a coffee, not enough to properly explore the Perast without the crowds approach of arriving on your own schedule.

Our Lady of the Rocks. An artificial islet, built up stone by stone over centuries on a submerged reef, facing Perast. The tour boat or a small shuttle takes you across in a few minutes; entry to the church and its small museum is usually a separate fee, a few euros, not included in the tour price. See the full visit guide for what’s inside.

Risan, when included, adds a stop for Roman floor mosaics at a small archaeological site — a quieter, less crowded add-on than Perast, and one most half-day tours skip in favour of more time at the two main stops.

The Blue Cave. This is the one stop that genuinely isn’t on the standard loop: it sits on the outer coast near Lustica, well outside the inner bay, and reaching it from Kotor is what pushes a tour from a half day to six-plus hours. Morning light gives the best colour inside the cave, which is one reason full-day tours tend to leave early. The Blue Cave boat trip guide has the detail on timing and what the light actually looks like at different hours.

Best time of day to go

Cruise ships can put 2,000 to 4,000 extra people into Kotor and Perast on a single call, and 2025 saw over 500 calls and more than 700,000 cruise passengers through the port across the season. The crush lands between roughly 10am and 4pm on days with ships docked; Perast’s small waterfront feels it as much as the old town does. Booking the first departure of the morning, before around 9.30am, or a late-afternoon and sunset slot after 5pm, avoids most of it — a sunset cruise is also simply a nicer version of the same trip, with the light doing more of the work.

Season matters too. Late May to mid-June and September give warm, swimmable water without the July–August peak crowds and prices; see the best time to visit guide for how that plays out month by month.

What to book, and what to skip

If your priority is simply seeing Perast and Our Lady of the Rocks from the water at the lowest cost, the shared half-day loop does the job — there’s little reason to pay for a private boat just for those two stops. If you want the Blue Cave as well, accept that it’s a full day, book an early slot, and treat the long transit as part of the trip rather than dead time.

Anyone weighing the shared-versus-private decision in more detail, including group-size break-even points, should read private vs group boat tour before booking. And if a boat isn’t essential to the plan at all — some travellers prefer driving the coast road themselves — the boat or car comparison lays out when each makes more sense. For a structured day built entirely around the water, the Kotor Bay by boat itinerary strings several of these stops into one plan, and the wider boat cruises category lists every water-based option around the bay, not just this loop.

Boat tours with children

The standard loop is short, mostly flat water, and involves no strenuous walking beyond Perast’s waterfront and the short island crossing, which makes it one of the easier boat trips in the bay for families. Tube-ride add-ons suit kids old enough to hold on through open-water stretches; the longer Blue Cave routes are a bigger ask for very young children given the total time on the water. The Kotor with kids guide covers how this fits alongside the rest of a family itinerary.

Frequently asked questions about Kotor Bay boat tours

How long does a Kotor Bay boat tour take?

The core loop to Perast and Our Lady of the Rocks takes 3 to 4 hours, including stops. Tours that also stop at Risan, Dobrota or the Blue Cave run 6 to 8 hours, since the Blue Cave sits near Lustica on the outer bay, well beyond the inner loop.

What’s included in a typical Perast and Our Lady of the Rocks boat tour?

Pickup from Kotor’s old town or marina, a scenic run past Dobrota and Prcanj, a stop in Perast with free time on land, and a short boat shuttle out to Our Lady of the Rocks, where the church entry fee is usually separate from the tour price.

Is a private boat tour worth the extra cost?

For a couple or a family it usually isn’t, since a shared group tour covers the same stops for a fraction of the price. A private charter earns its cost mainly for larger groups splitting the boat fee, or for anyone who wants to set their own stops and timing.

Can I visit the Blue Cave on a Kotor Bay boat tour?

Yes, but only on the longer full-day format. The Blue Cave is near the Lustica peninsula, not in the inner bay, so tours that include it add two to three hours of extra boat time each way and usually leave Kotor in the early morning.

What’s the best time of day to book a boat tour from Kotor?

A morning departure before 9.30am or a late-afternoon slot after 5pm avoids the cruise ship crowd, which fills the old town and Perast’s waterfront between roughly 10am and 4pm on days with ships in port.

Do I need to book in advance in July and August?

Yes. Shared group speedboats sell out a day or two ahead in high season, and private charters get booked out further in advance for the popular morning and sunset slots.

Is the Kotor Bay boat tour suitable for kids?

The standard loop is a gentle, mostly flat-water run and works fine for children. Tube-ride add-ons and the longer Blue Cave routes are better suited to older kids who can handle a longer day on open water.

Can I just take the public boat to Our Lady of the Rocks instead?

From Perast itself, yes, small boats shuttle visitors out to the island for a few euros each way and you can skip the rest of the loop. Reaching Perast from Kotor without a tour means driving, taking a bus, or a taxi, since there’s no direct public boat from Kotor’s marina.
