Snorkel, then sit by the peacocks. This 4-hour sea tour turns Dubrovnik’s coastline into real time on Lokrum Island plus two swim stops, including Betina Cave.

I love how you get sweeping views from the water of Dubrovnik’s City Walls and Fortress Lovrjenac, with an easygoing pace that feels calmer than day-trip hustling. I also love Lokrum’s combo of strolling (Botanical Gardens and Benedictine grounds) and quick hits of fun, from free-roaming peacocks to Game of Thrones filming spots.

One thing to plan for: your swimming depends on good weather, and you’re on a schedule, not an all-day island hangout.

Key takeaways before you go

• Glass-bottom and sighting cruise views: You’ll glide past major sights from the sea, with underwater viewing that makes the trip feel more special than a basic ferry hop.
• Lokrum time that’s enough to choose your vibe: Walk gardens and monastery grounds, then still have time to float at Mrtvo More and explore at your own pace.
• Two swim stops, two different moods: St. Jacob is a classic beach moment; Betina Cave is the main adventure.
• Betina Cave is sea-only: Access is by boat, and your snorkeling plan may include a dramatic entry point.
• Bring cash for Lokrum entry: The island fee is separate, and you pay on the spot in cash.

Finding Your Boat at Dubrovnik’s Old Port (Lokanda Peskarija)

The tour starts at the Old city port area, next to Lokanda Peskarija. When you arrive, look to your left for the check-in desk, and find the team with a LOKRUM TOUR sign.

This matters because Dubrovnik’s ports can look like a lot of similar-looking boats and counters. Once you spot the correct sign, check in quickly, then get your beach kit ready because the day is built around water time.

Expect a relaxed handoff: you meet the host/greeter in English and then get onboard. Depending on your departure point, the transport is described as a glass-bottomed boat from Dubrovnik and a speed boat from Cavtat.

The Sighting Cruise From Dubrovnik: City Walls and Lovrjenac Fortress

The first “wow” comes early as you cruise out and take in Dubrovnik from the water. You get passes and views tied to the city’s shape: the iconic City Walls and Fortress Lovrjenac.

What I like about this part for you is simple: it’s a low-effort way to orient yourself. From the water, you quickly understand how Dubrovnik clings to the coastline, and you can spot landmarks without squinting at the map.

As you approach Lokrum, you also cruise past Lokrum Cave and the island’s famous nudist beach area. Even if that’s not your thing, it adds to the sense that Lokrum is its own world—wild, rocky, and very different from the city’s stone streets.

Lokrum Island Free Time: Gardens, Benedictine Grounds, and Mrtvo More

After cruising around, you disembark for about two hours if you’re departing from Dubrovnik, or about 2.5 hours if you’re departing from Cavtat. That timing is a real consideration: it’s long enough to see the highlights, but short enough that you’ll want to move with purpose.

Lokrum is a UNESCO Heritage site, and the on-island experience is built around walking paths and ruins/grounds. You’ll have time to explore the Botanical Gardens and the Benedictine monastery area, where the island’s calm feels like a break from the city’s intensity.

Then there’s the Mrtvo More, also known as the Dead Sea of Lokrum. You’re not just sightseeing here—you can dip your toes and enjoy the feeling of saltwater buoyancy, which is one of those small moments that ends up being a highlight for many people.

Also, peacocks roam freely on the island. That’s not a staged “tour moment.” They just show up, and you’ll see them where you’re walking and taking pictures, usually acting like they own the place. It’s charming, and it makes Lokrum feel alive.

Game of Thrones Filming Locations on Lokrum (Plus How to Spend Your Two Hours)

Lokrum’s fame isn’t only nature. You’ll spot Game of Thrones filming locations while walking the island, including the Iron Throne. If you’re a fan, it’s a fun way to connect the island’s spots to what you’ve seen on-screen.

If you’re not a fan, it still works. The filming spots act like “anchors” on a self-guided walk. They give you an easy reason to pick a direction and keep moving instead of drifting.

With only around two hours, I’d treat Lokrum like this:

• First pass: pick up the big landmarks (gardens/monastery area).
• Second pass: slow down near the peacocks and the Dead Sea spot.
• Quick photo breaks: take them when you’re already standing still, so you don’t lose time.

One more practical note: Lokrum has cafes and places to rest. That’s helpful if you’re traveling in peak heat and want a break before the return swim portion.

St. Jacob (Plaža Sveti Jakov): A Clean Swim Stop With Dubrovnik in the Distance

Next is the beach stop at Plaža Sveti Jakov. You’ll get about 40 minutes for swimming and snorkeling.

This segment is shorter than Lokrum, but it’s purpose-built. The beach is where the tour lets you shift from walking trails to actual water time, with views back toward Dubrovnik’s coastline.

A heads-up from real-world experience: this beach area can get very busy. If you’re hoping for wide-open shoreline space, you may find the crowd concentrates in the most accessible sections. It doesn’t ruin the stop, but it changes the vibe.

Also, the sea entry can feel different depending on where you swim. Bring your patience. The water is the point here, and once you’re in, the views and conditions make the short stop feel worthwhile.

Betina Cave Beach: Snorkeling in a Sea-Only Setting

The main adventure stop is Betina Cave, accessible only by sea. You’ll get about 30 minutes to swim and snorkel around the cave area and beach inside it.

This is the kind of stop that makes the tour memorable because it’s not just “another beach.” The cave is its own underwater/sea-world, and the tour includes jumping/snorkeling options right from the boat zone. A few notes you should know:

• Access is from the water, not from a land path.
• The cave entry can be a small “event,” especially if you’re deciding whether you’re comfortable with jumping in.

If you’re traveling with kids or someone who’s unsure about jumping from the boat, you’ll still get something here from snorkeling and watching the cave area, but the cave itself is the star. It’s described as a lovely swimming spot, and many people treat it as the highlight of the entire trip.

On the Water: Glass-Bottom Viewing and Audio Guidance That Keeps You Oriented

The tour includes a glass-bottomed boat experience (or a speed boat depending on departure point). This is more than a gimmick. Underwater views help you connect the snorkeling stops to what’s happening in the water, so you’re not just jumping in blind.

You also get an English audio guide. The audio helps you understand what you’re seeing on the cruise sections (city sights and the approach around Lokrum). Even if the skipper isn’t doing a full live commentary, the audio keeps the tour from feeling like a free-for-all.

Some boats have music playing. If you’re sensitive to sound, be aware that the vibe can be upbeat rather than silent-library calm.

Price and Value: Why $38 Often Feels Fair (Then Add Lokrum Entry)

The advertised price is $38 per person, for a 4-hour experience that includes a sightseeing cruise, boat transfer, and swimming/snorkeling gear plus an English audio guide.

Then comes the big separate add-on: Lokrum Island entry is not included. The fee is €30 for adults and €5 for kids over 6, paid in cash on the spot at the meeting point/arrival.

So is it still good value? For many people, yes—because you’re paying for three things in one:

• Sea views and sightseeing that you’d otherwise need separate transport to access.
• Time on Lokrum that’s hard to replicate in one quick ferry ride.
• Snorkeling and cave access tied to this specific boat route.

If you’re comparing “just getting to the island,” this tour costs more once you add Lokrum entry. But it also gives you structured stops at St. Jacob and Betina Cave without coordinating multiple pieces yourself.

One more practical point: since Lokrum entry is cash-only, I’d bring the money before you step onto the boat. People get tripped up by this detail, and it’s an easy way to start the day stressed.

Who This Tour Fits Best (And Who Might Want Another Plan)

This is a strong fit if you want a half-day that includes both sightseeing and water play. It’s especially good if you don’t have time for a longer multi-stop day in Dubrovnik.

It’s not suitable for:

• People with mobility impairments
• Non-swimmers

So if swimming isn’t your thing, you may feel pressured by the schedule. Likewise, if you’re uneasy about water entry points, it’s worth thinking hard before booking, especially because Betina Cave is part of the “you’re already in the sea” experience.

On the plus side, the tour is described as not overly crowded at times, with one group size called out around fourteen. That’s enough people for company, but still small enough that the day doesn’t feel like a cattle queue.

Practical Tips to Make Your 4 Hours Feel Easy

Bring the right stuff and the day runs smoother:

• Beachwear and a towel (you’ll want to dry off between stops).
• Cash for the Lokrum entry fee.
• A basic swim-ready mindset for snorkeling moments.

Also plan around weather. The tour notes that it requires good weather, and if conditions are rough, your water time could be affected.

Finally, pack for heat. Dubrovnik and Lokrum can feel intense in the day sun, and Lokrum’s free time is walking-heavy. Drink water when you can, and don’t save all your sunscreen for St. Jacob.

Should You Book the Lokrum Island and Betina Cave Tour?

Book it if you want a tight, high-payoff day: Lokrum walking + two swimming stops + sea views of Dubrovnik’s walls. The structure works well when you’re short on time but still want an authentic nature-and-water break.

Skip it (or look for an alternative) if you’re a non-swimmer, have mobility challenges that make getting on/off boats difficult, or you’re likely to bail when the schedule pushes you toward quick swim windows. Also consider whether you’ll be comfortable with the sea-only nature of Betina Cave and the way you access it from the boat.

If you do book, you’ll get exactly what the trip is built for: sea scenery, Lokrum’s gardens and monastery atmosphere, and a cave snorkeling stop that’s hard to recreate any other way.
