Kotor Bay by boat: a 3-day itinerary

The Bay of Kotor is really two boats’ worth of sightseeing, not one. Inside the bay, past Perast and Risan, the water is flat and the villages are close together: a slow wooden water taxi is the right tool, and rushing it defeats the purpose. Outside the bay, toward the Blue Cave and Mamula Island, the distances open up and the sea gets a bit of chop: that’s a speedboat job, done as an organised half-day trip rather than a leisurely potter. This itinerary keeps the two apart deliberately, because mixing them into one long day means neither gets done properly.

Three days is enough to do both properly with a spare morning. Two focused days would also work if you’re short on time; see how many days in Kotor and the bay if you’re still deciding. For the wider choice between chartering your own boat and joining a group, read private vs group boat tour in Kotor Bay before booking anything.

Day 1: Kotor old town, then the baroque villages by water taxi

Spend the morning on foot in Kotor old town: the walls, Saint Tryphon’s cathedral, and the maze of stone lanes take about two to three hours without rushing. Full walking route in the Kotor old town walking guide. Aim to be done by late morning, both because the cruise-ship crowds thicken from 10am and because the boat leg of the day works better in the calm morning-into-early-afternoon window.

From the old town harbour or the Kotor waterfront, wooden water taxis and small group boats head up the inner bay toward Perast, about 12km and 20 minutes by boat. Perast itself has no beach-resort sprawl, just a single stone street lined with baroque merchant palaces built on the wealth of 17th and 18th century sea captains — background in the Boka’s 18th-century captains.

From Perast’s harbour, a short shuttle boat (a few euros, pay on board) crosses to Our Lady of the Rocks, the artificial islet built up over centuries on rocks fishermen and sailors deliberately sank there. The church and its small museum take 30-45 minutes; full detail in the Our Lady of the Rocks visit guide.

A combined tour covering Perast and Our Lady of the Rocks from Kotor is the simplest way to do this leg without negotiating a private taxi:

a two-hour Perast and Our Lady of the Rocks boat tour timed for sunset

is a straightforward option that also gives you the softer late-afternoon light for photos, though it means doing Perast twice if you also stop there independently in the morning — worth planning around rather than double-booking.

After Perast, the more thorough version of this day continues further up the bay to Risan, 30km and about 25 minutes on from Perast, known for a well-preserved Roman villa with mosaics rather than baroque churches; see the Risan Roman mosaics guide. A guided option that strings Risan, the Blue Cave viewing, and Our Lady of the Rocks together in one run is:

a boat tour linking Risan with Our Lady of the Rocks near Perast

— useful if you’d rather have one operator handle the whole inner-bay loop instead of stitching taxis together yourself.

On the way back toward Kotor, the boat naturally passes Dobrota, a strip of more baroque sea-captain villas that most day-trippers skip entirely because it has no dedicated stop of its own; the Dobrota baroque palaces walk covers it as a shore walk rather than a boat stop, worth combining with Kotor on foot another day.

If your route or operator allows a brief stop at Prčanj or Stoliv, take it — both are small, quiet, and rarely visited by tour groups, covered together in the Stoliv and Vrmac hidden villages guide. Neither has much beyond a church and a waterfront, which is exactly the appeal after a day of monuments.

Back in Kotor by early evening, that’s a full day: old town on foot, then baroque villages by water. For the fuller version of this loop as a standalone half-day, see the Kotor Bay boat tour guide and, if Perast’s crowds put you off a first attempt, Perast without the crowds covers the quieter hours.

Day 2: south to the Blue Cave and Mamula Island by speedboat

This is a different boat, a different pace, and — if you book the early slot — a different start time. Group speedboat tours from Kotor or Tivat to the Blue Cave, near Rose on the Lustica side, typically run 40-60 EUR per person and take three to four hours including the crossing and a swim stop. Book the earliest departure you can find, ideally 7am. Between roughly 10am and 2pm in July and August the cave is genuinely crowded — ten-plus boats stacking up outside a cave mouth that fits two or three comfortably, with a queue to swim inside. Early morning, before the day-boats leave the marinas, it’s close to empty and the light through the water is, if anything, better.

a ticketed Blue Cave tour departing from Kotor

covers the standard group version of this run. If you’d rather set your own timing and skip the shared-group waiting-around, a private option is:

a private speedboat charter to the Blue Cave

which costs more per person but lets you insist on the 7am slot without depending on a group minimum.

On the way south or on the return leg, most operators route past Mamula Island, the star-shaped Austro-Hungarian fortress sitting on its own islet off Herceg Novi. It’s worth saying plainly: you do not go ashore. The fortress was converted into a private luxury hotel, and its public-facing areas are closed to day visitors and passing boats alike — you see the walls from the water and that’s the extent of it. The Mamula Island fortress guide covers what’s visible from a passing boat and its wartime history as an internment camp, which is a heavier story than the postcard view suggests.

For a livelier version of the same south run with a stop for towed water sports, there’s:

a Bay of Kotor speedboat tour with a tube ride included

— aimed more at a fun afternoon on the water than at the Blue Cave itself, worth knowing about if travelling with teenagers who’d rather be towed on a tube than queue to swim into a cave.

Back in Kotor or Tivat by early-to-mid afternoon, the rest of day 2 is free. If the sea trip left you wanting more water time without the crowds, sea kayaking in Kotor Bay is a slower, self-powered alternative for another day. Full detail on this southern excursion, including which departure point suits you better, is in the Blue Cave boat trip guide.

Day 3: Tivat, Porto Montenegro, and a slower finish

The last day is deliberately lighter. Tivat is 20 minutes from Kotor by road or, if you’d rather keep it on the water, a short taxi-boat hop across the bay. Its centrepiece is Porto Montenegro, a marina development built where a former Yugoslav naval yard used to be — superyachts, waterfront cafés, and a small naval heritage collection. It’s an easy, unhurried morning: coffee on the marina, a walk along the pontoons, none of the climbing or crowd-dodging of the first two days. The Tivat and Porto Montenegro guide has the practical layout.

If you have a car, or don’t mind a taxi, the Njeguši ridge road above Kotor is a scenic if narrow detour from here — not part of the boat theme of this itinerary, but worth knowing about for a fourth day; the Njeguši village guide covers it. For those without a car for the whole trip, this itinerary was built to need none: see the Montenegro without a car guide for how the rest of the coast connects by bus, ferry, and boat instead.

Close the trip with a short water crossing rather than a long drive if you’re heading toward Herceg Novi or onward into Croatia: the Kamenari-Lepetane ferry guide explains the crossing, at 5 EUR for a car, that cuts out the long drive around the bay’s inner arm.

FAQ: touring the Bay of Kotor by boat

Can you do the whole bay in one day by boat?

Not comfortably. The Boka villages and the Blue Cave/Mamula run use different boats leaving from different jetties, at different speeds. Combining both in one day means an early start and a rushed afternoon; splitting them over two mornings is more realistic.

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

Yes, for the Blue Cave and Mamula speedboat tours. Departure slots fill by mid-morning in high season and the good operators cap group size. Water taxis to Perast run more flexibly, but a fixed sunset slot is still worth reserving a day ahead.

Can you go inside Mamula Island fortress?

No. The Austro-Hungarian fortress on Mamula was converted into a private luxury hotel and its public areas are closed to day visitors and boat passengers. Tours circle the island so you can see the star-shaped walls from the water; nobody goes ashore.

Is the Blue Cave worth it if it’s crowded?

It’s worth it at the right hour. Between 10am and 2pm in July and August, ten or more boats can be jostling for space inside a cave that comfortably holds two or three. A 7am departure, which some operators now offer, gives you the cave close to empty and the light is arguably better.

How rough is the sea on the south run to Rose and Mamula?

The Boka’s inner waters are sheltered and calm almost year-round. Once a speedboat clears the strait at Verige and heads toward Rose and Herceg Novi, it’s exposed to the open Adriatic, and a summer afternoon breeze (the maestral) can make the return choppier than the outward leg. Operators cancel or delay in a strong bura wind.

Can I do this without a car?

Yes, that’s the point of the itinerary. All three days work from Kotor’s old town or harbour on foot, plus organised boat pickups. A car adds nothing on the water days and mainly complicates parking, which is scarce and payable near the old town in summer.

What should I bring on the boat days?

A hat, reef-safe sunscreen, a light jacket for the speedboat spray, water shoes if you plan to swim off the boat near Mamula, and cash in euros for small vendors at Our Lady of the Rocks and Perast, since not everyone takes cards.
