Dubrovnik: Lokrum Island and Betina Cave Boat Tour

Dubrovnik looks best from the water, and this tour gives you that view before taking you to Lokrum Island, St. Jacob beach, and Betina Cave. You cruise past the Old Town walls and Lovrjenac Fortress, then have two hours to wander among peacocks, monastery ruins, gardens, and the island’s famous salt lake.

I like the useful mix of sightseeing and swimming, especially the glass-bottom boat and the chance to reach Betina Cave by sea. I also like the free time on Lokrum, since you can choose between walking, the Botanical Gardens, the Iron Throne, or a swim instead of being led from one stop to the next.

The main catch is the extra Lokrum entry fee: €30 for adults and €5 for children over six, paid in cash at the meeting point. St. Jacob beach can also feel crowded, and two hours on Lokrum may leave you wishing for more island time.

Key points to know before you book

• Lokrum gets the most time: You have about two hours on the island from Dubrovnik, enough for a focused visit but not a full exploration.
• The views begin at the Old Town port: The route passes Dubrovnik’s walls, Lovrjenac Fortress, Villa Sheherezade, and the historic Lazarets.
• Swimming is built into the plan: St. Jacob beach offers about 40 minutes, followed by roughly 30 minutes at Betina Cave.
• The extra fee matters: The €30 adult Lokrum admission is not included in the advertised tour price and must be paid in cash.
• The boat experience varies by departure point: Dubrovnik departures use a glass-bottom boat, while Cavtat departures use a speedboat.
• This is an active half-day: You need to manage rocky beaches, boat access, swimming, and snorkeling without mobility support.

A four-hour route with three very different stops

This is a compact sea outing rather than a full-day island expedition. The schedule gives you a broad taste of Dubrovnik’s coast, then sets aside enough time for Lokrum to feel like more than a quick photo stop.

From Dubrovnik, the meeting point is at the Old City port beside Lokanda Peskarija Restaurant. Look for the booking desk marked LOKRUM TOUR. After check-in and payment of the island admission fee, you board the glass-bottom boat.

The exact pace can vary with sea conditions and the captain, but the planned route is straightforward:

• About 30 minutes of coastal sightseeing around Dubrovnik
• About two hours on Lokrum
• About 40 minutes at St. Jacob beach
• About 30 minutes at Betina Cave
• Return to the Old City port

From Cavtat, the boat is a speedboat and the Lokrum stop is listed at about two and a half hours. The supplied meeting instructions apply to Dubrovnik, so check the departure details carefully if you choose Cavtat.

Dubrovnik’s walls look different from the water

The first section is less about swimming and more about getting your bearings. From the sea, Dubrovnik’s pale stone walls rise directly above the water, with the Old Town packed behind them. You also pass Lovrjenac Fortress, the sturdy fort perched outside the western walls.

This is one of the tour’s strongest features because the view cannot be copied from a street or city wall. You see the defensive line from the angle it was built to face, with the sea between you and the old city.

An English audio guide supplies historical information as you cruise. Several people have also praised captains such as Ivo, as well as Anastasia and Nikola, for being friendly and helpful. The audio commentary is useful for travelers who find live commentary hard to hear over an engine, though it means the historical explanation may feel less personal than a walking tour with a dedicated guide.

The boat ride is generally described as comfortable and not overcrowded, though group size depends on the departure. One reported group had 14 people, and another booking had only two participants. That range matters: you may get a small-group feel, but you should not assume a private boat.

Lokrum gives you two hours to choose your own pace

Lokrum is the heart of the trip. This wooded island sits just off Dubrovnik, but it feels far removed from the city once you leave the shore. The tour allows about two hours here from Dubrovnik, with no fixed walking route.

You can head toward the former Benedictine monastery and its grounds, walk through the Botanical Gardens, or find the Game of Thrones-related Iron Throne. Peacocks roam freely around the island, adding a slightly surreal note to the old stone and thick vegetation.

The Mrtvo More, or Dead Sea, is a saltwater lake connected to the Adriatic. It is an easy place to pause and cool off, though you should still bring beachwear and a towel if swimming is part of your plan. The island also has cafés, but food and drinks can be costly, so you may prefer to bring a snack or plan to buy only a drink.

Two hours is enough for a satisfying first look. You can see the monastery area, find the throne, watch the peacocks, and spend some time in the water. It is not enough for a slow visit to every trail, garden, and swimming spot. If Lokrum is your main reason for coming to Dubrovnik, a separate island visit by ferry may suit you better.

That time limit is the most common tradeoff in the schedule. The boat also takes you to St. Jacob beach and Betina Cave, so the operator is aiming for variety. I think that works well for a first visit, but you may wish the beach stop were shorter if you prefer gardens and walking to swimming.

The island itself is not presented as a guided walking tour. You get free time, supported by the boat’s audio information and the practical help of the crew. That independence is a plus for couples, families with older children, and anyone who dislikes being kept in a tight group.

St. Jacob beach is scenic, but not always peaceful

After Lokrum, the boat heads to Plaža Sveti Jakov, or St. Jacob beach. The stop lasts about 40 minutes, giving you time to swim, snorkel, or simply look back toward Dubrovnik.

The view toward the city is excellent. You get a different picture of the walls and shoreline, this time from a beach rather than from open water. The beach is surrounded by natural scenery, and the clear water makes it a good place to use the supplied snorkeling gear.

There is a practical warning here: the beach is rocky and can be crowded, particularly in the busy summer season. One older participant found getting into the water difficult, so this is not the easiest stop for anyone with mobility concerns. Bring footwear that can handle a rocky shoreline if you have it, and do not expect a broad sandy beach.

A café or beach facility may offer drinks and ice cream, but the tour information does not include food or refreshments. The safest plan is to carry water and cash. If you want a long, quiet beach session, 40 minutes may feel short. If you want a quick swim after walking around Lokrum, the timing works well.

Betina Cave is the trip’s most playful finish

The final swimming stop is Betina Cave, a small beach and sea cave reachable only by boat. This gives the outing a sense of discovery without requiring a long walk or difficult route inland.

You can jump from the boat, swim into the cave, and snorkel around the seabed. For many people, this is the highlight because it combines a memorable setting with active time in the water. The cave stop lasts about 30 minutes, so you have enough time for a swim and a few photographs, but not for a slow beach afternoon.

Access requires a small jump from the boat. That detail is important for families and anyone nervous around open-water entry. You can enjoy the view without getting in, but the stop is designed mainly for swimming and snorkeling. Non-swimmers are specifically not suited to this tour, and children should be comfortable in the sea and able to follow crew instructions.

The cave is also where conditions matter most. The activity requires good weather, and the captain may need to adjust the swimming portions when the sea is rough. On a clear, calm day, the combination of cave walls, open water, and Dubrovnik’s coast makes a strong finish.

What the $38 price really covers

At $38 per person, the tour is reasonably priced for a four-hour boat outing with transport, coastal sightseeing, snorkeling equipment, an English audio guide, and three distinct stops. It is particularly good value if you have limited time in Dubrovnik and want to combine the city from the water with Lokrum and two swimming locations.

But the advertised price does not include Lokrum admission. Adults pay €30 and children over six pay €5, in cash at the meeting point. That adult fee changes the calculation considerably, so budget for the total cost rather than treating $38 as the final amount.

The fee is not a small add-on, and several people have wished it were included in the booking price. The cash-only rule is the bigger practical issue. Bring euros before you arrive at the port, since arriving without enough cash can create stress before the boat leaves.

You are also paying for transport between places that are not easily combined on foot. A ferry can take you to Lokrum, but this tour adds the coastal views, St. Jacob beach, Betina Cave, swimming gear, and a return by boat. If you only want Lokrum, the regular ferry may be the simpler choice. If you want several water stops in one morning or afternoon, the boat tour earns its price more easily.

Who will enjoy this boat trip most

I would choose this for you if you have one or two days in Dubrovnik and want a broad introduction to the coast. It gives you city views, island time, a beach, a cave, and several chances to get in the sea without committing your whole day.

It also suits people who like a flexible visit. On Lokrum, you can walk, swim, see the gardens, find the Iron Throne, or sit with a drink. You are not forced into one group route.

Swimmers, couples, active families, and small groups are the best match. The supplied snorkeling equipment saves you from arranging your own gear, though you still need beachwear and a towel.

I would think twice if you do not swim, dislike rocky shorelines, or have mobility limitations. The boat ride and island scenery can still be enjoyable, but the tour’s main attractions involve getting in and out of the water. It is also not ideal if you want a quiet, detailed botanical or historical visit, since the island time is limited.

Simple ways to make the four hours better

Bring cash in euros for the Lokrum admission fee, plus money for any café purchase. Carry water, beachwear, a towel, and sun protection. The tour description specifically advises beachwear, cash, and a towel, and all three are genuinely useful here.

Wear something that dries quickly. You may swim at Lokrum, St. Jacob beach, and Betina Cave, and there is not much reason to stay completely dry once the first swimming opportunity appears.

Arrive at the Old City port with enough time to find the LOKRUM TOUR desk beside Lokanda Peskarija. The port can be busy, so do not rely on spotting the boat from a distance.

Expect commentary to come mainly through the English audio guide, even though the captain and crew can answer questions and help you on and off the boat. The audio system has been praised for being clear, while some people have enjoyed the captain’s music as part of the ride. Music volume may not suit everyone, so bring patience if you prefer a quiet cruise.

The company offers cancellation up to 24 hours before departure for a full refund, and you can reserve while paying later. Weather matters, so keep an eye on the forecast and remember that the swimming portions depend on safe conditions.

Should you book the Lokrum and Betina Cave tour?

Book it if you want an efficient half-day with strong coastal views, independent time on Lokrum, and several chances to swim. The Old Town walls from the sea, the free-roaming peacocks, and the short swim into Betina Cave give the outing more variety than a simple island ferry.

Skip it if your priority is a long Lokrum visit, a sandy beach, or a fully guided historical tour. You should also avoid it if you cannot swim comfortably or find rocky water access difficult.

For most active visitors, the tour works best as an introduction rather than a definitive visit to Lokrum. Bring the extra €30 admission fee in cash, accept that St. Jacob beach may be crowded, and you get a lively, well-packed look at Dubrovnik’s coast in four hours.
