Tivat to the Blue Cave by speedboat: the faster route out of the bay

The geography that makes Tivat the shortcut

Every Blue Cave trip out of the Bay of Kotor has to solve the same problem: the cave sits outside the bay altogether, on the open-sea side of the Luštica peninsula, close to Herceg Novi. The bay itself is not a fjord but a ria, a drowned river valley, and it runs inland for roughly 28 kilometres from the open Adriatic to the innermost basin where Kotor sits. A boat leaving from Kotor has to sail out along the whole of that shape before it even reaches open water.

Tivat sits in a different position. It occupies its own shorter arm of the bay, closer to the strait at Verige and the exit past Herceg Novi, so a speedboat leaving Tivat’s marina reaches open water in a few minutes rather than the better part of an hour. The straight-line distance from Tivat to the Blue Cave is around 15 to 20 kilometres depending on the exact mooring used, and a fast RIB covers that in 25 to 35 minutes in normal conditions. From Kotor, the equivalent run is closer to 40 to 50 kilometres by water once you account for the shape of the inner bay, and boats typically need 1 to 1.5 hours to cover it.

That difference of roughly an hour each way, two hours over a return trip, is the entire case for basing a Blue Cave day around Tivat rather than Kotor. It is not a marginal saving. On a half-day tour it can be the difference between three hours at sea and five.

Sailing times compared, stop by stop

Starting point	Distance to Blue Cave	Typical one-way time	Notes
Tivat marina / Porto Montenegro	~15–20 km	25–35 min	Fastest option, minimal inner-bay sailing
Kotor old town waterfront	~40–50 km	60–90 min	Full length of the inner bay first
Herceg Novi	~5–10 km	10–20 min	Closest, but fewer operators and less choice
Budva (road transfer + boat)	N/A by sea	~45 min drive + 20–30 min boat	Usually sold as a combined transfer tour

These are sailing times only, in reasonable summer conditions on a standard 8 to 12 metre speedboat. A slower, more sheltered route hugging the Luštica coastline instead of cutting across open water can add 10 to 15 minutes each way; some skippers choose that route deliberately when there is wind chop outside the bay.

What a Tivat-based trip typically includes

Tours leaving from Tivat, often from the Porto Montenegro marina area, are usually built as half-day outings of three to four hours rather than full-day expeditions. A standard structure looks like this: leave the marina, sail past the tip of Luštica, stop at the Blue Cave for 20 to 30 minutes of swimming and photos, then add one or two secondary stops before heading back.

this Blue Cave, Herceg Novi and Lady of the Rocks combination from Tivat is a fair example of how operators package the shorter Tivat route: it uses the time saved on sailing to add a stop at Our Lady of the Rocks off Perast and a look at Herceg Novi’s waterfront, which would be a much longer day if it started from Kotor instead.

Other operators lean into speed and swimming rather than sightseeing stops. a Tivat trip that pairs the Blue Cave with the old submarine tunnel and Žanjice beach keeps the itinerary tighter: cave, a disused Yugoslav-era submarine pen cut into the cliff, and a swim stop at one of the better beaches on the Žanjic side of the peninsula, all within a half-day window that a Kotor departure could not match without cutting corners elsewhere.

For groups who want speed on the water itself rather than just a shorter route, a Tivat speedboat tour that adds dolphin watching and tubing is aimed more at the boat ride as the activity, with the Blue Cave as one stop among several rather than the sole focus. It suits a group that wants an active afternoon rather than a slow, photograph-heavy visit.

Two other tours worth knowing about are not primarily Blue Cave trips but touch the same ground: a Bay of Kotor and Tivat electric car tour and a private car option covering Budva, Kotor and Tivat in one day. Neither replaces a boat trip, but they are useful if bad weather rules out the water and you still want to see the Tivat side of the bay.

What the Blue Cave is actually like once you get there

The cave itself is modest in size, a shallow sea cavern rather than a cathedral-scale space, and its reputation rests almost entirely on light, not scale. When the sun is high and the water is clear, light entering through the submerged opening scatters and turns the interior a strong electric blue; swimmers inside appear to glow. On an overcast day, or once a dozen boats have churned the water and dozens of swimmers have stirred up sediment, the effect can be underwhelming, closer to a grey-green cave than the postcard version.

Timing therefore matters more than which operator you book. Late morning, roughly 9.30am to 11.30am, tends to give the best combination of sun angle and low boat traffic, before the bigger midday groups arrive and before afternoon wind picks up outside the bay. Because the crossing from Tivat is short, an early-morning Tivat departure can realistically reach the cave and still be swimming before 10am, something a Kotor departure struggles to manage without a genuinely early start.

The cave sits close enough to Mamula Island, the round fortress-turned-hotel off Herceg Novi, that many boats pass it on the way, even without stopping. Ask before booking whether a landing is included or whether it is a photo pass only, since the two are priced and timed very differently.

Comparing Tivat with a Kotor departure on the same trip

It is possible to book a Blue Cave tour that starts in Kotor, and plenty of operators sell exactly that, usually as a full-day rather than half-day product. The trade-off is straightforward: more time on the water covering ground that offers little to look at beyond the scenery of the inner bay itself, which is attractive but already visible from land on a Kotor Bay boat tour or from the old town waterfront without needing to burn boat time crossing it twice.

Some Kotor-based operators shorten the trip by transferring guests to Tivat or Herceg Novi by road first and boarding a boat there, effectively borrowing the Tivat advantage while still selling the tour as departing from Kotor. That is a reasonable compromise if you are staying in Kotor and do not want to change hotels, but it is worth asking directly whether the itinerary includes a road transfer, since the answer changes the total length of the day by an hour or more.

For a broader look at whether a private boat or a group tour suits your plans better on this stretch of coast, see the comparison in the private versus group boat tour guide. And for the wider question of where to base a stay in the bay at all, the Tivat versus Kotor guide sets out the trade-offs beyond just this one boat trip.

Getting to Tivat if you are not already staying there

Tivat’s airport is the closest of the region’s three to the town itself, a taxi ride of well under 20 minutes from the terminal to the marina area. Anyone flying in specifically for a short coastal trip, rather than basing a longer stay in Kotor, can reasonably fly into Tivat, do a Blue Cave morning, and move on the same day; details on transfer options are in the Tivat airport transfer guide.

Coming from Kotor by road instead, the drive to Tivat is short, around 20 minutes via the tunnel road rather than around the bay, and parking near the Porto Montenegro marina is more straightforward than trying to park in central Kotor, where space is tight and often payable in season; see the Kotor parking guide if you are leaving a car behind for the day. Several tour operators also offer a hotel pickup in Kotor that includes the road transfer to Tivat as part of the package, which removes the need to arrange transport separately.

When to book and what to expect on the water

July and August bring the heaviest boat traffic to the Blue Cave, and the best light window in late morning is also the busiest slot, so small-group and shared speedboats from Tivat routinely sell out a day or more ahead in peak season. Late May, June and September offer calmer water, fewer boats jostling for space inside the cave, and a similar sea temperature to July for anyone mainly after a swim rather than beach weather.

Whichever month, check what the listing actually includes: swimming time inside the cave, snorkelling gear if offered, and whether the price covers just the boat or also a guide narrating the passing coastline. Life jackets are standard on speedboats regardless of swimming ability, and most operators ask guests to be able to enter and exit the water via a boat ladder, which is worth flagging in advance for anyone with limited mobility. For a wider view of how a boat day fits into a longer stay around the bay, the Kotor Bay by boat itinerary sets out a fuller route beyond the Blue Cave alone.

The bottom line

If the Blue Cave is the priority and you have a choice of base, Tivat wins on time, not novelty. A shorter crossing means more time actually in the water, a better chance of catching the cave before the light or the crowds turn, and room to add a stop like Our Lady of the Rocks or Žanjice beach without turning the day into a marathon. Kotor’s inner bay is worth its own boat trip on a different day; it is simply the wrong side of the bay to start a Blue Cave run from if minutes on the water matter to you.
