The Itinerary Breakdown

Departure and Scenic Sea Views

From the moment you set off from Dubrovnik Old Town port (or nearby locations like Cavtat, Mlini, and Srebreno), you’re greeted with the chance to admire breathtaking views of Dubrovnik’s medieval walls and terracotta rooftops from the water. We loved the way the boat ride itself became part of the adventure—cruising along the coastline with the wind in your hair, tunes playing, and the sun shining. Many reviews mention the friendly crew, especially guides Ivan, Mario, and Dora, who keep the atmosphere lively and informative.

Koločep Island and the Blue Cave

Your first stop is Koločep Island, home to the famous Blue Cave. This cave is a highlight, especially because it’s accessible only by swimming through a narrow entrance—so bring your snorkel gear! Inside, the cave glows with a magical turquoise light, thanks to sunlight reflecting off the sea. Reviewers rave about how mesmerizing the light is, with one mentioning how “the glow reflected from the sea” makes the experience unforgettable.

The cave’s interior offers great photo moments and a chance to float in the crystal-clear water. For those feeling adventurous, some cliffs nearby are perfect for a quick jump—though be cautious of the waves, as one reviewer noted the first cave entrance can be a bit chaotic with boats and strong waves.

The Green Caves and Snorkeling

Next, you’ll visit the Three Green Caves on Koločep Island. Two of these caves are welcoming for easy snorkeling, allowing you to float around and take in the stunning scenery beneath the surface. The third is a narrow passage that leads swimmers through the island—very unique and exciting, especially for those who love a quick swim through a natural tunnel. Multiple reviews mention how these caves are “breathtaking” and that the snorkeling gear provided made it effortless to enjoy the underwater sights.

Sunj Beach on Lopud Island

The final stop is Sunj Beach, a famous sandy stretch on Lopud Island, with shallow turquoise waters perfect for relaxing or swimming. The crew anchor the boat close to shore, making disembarkation easy—even if you’re with kids or less mobile.

Here, you can unwind on free sunbeds under blue umbrellas, order a cocktail, and just soak up the sun. Many visitors note how “the beach is beautiful with soft sand and stunning water,” and the optional drinks (like cocktails or beers) add to the leisurely vibe. It’s a perfect spot for a laid-back afternoon, especially if you want to escape the crowds and have some quiet time.

Return Cruise

On the way back, the boat cruises along the coast, offering a last chance to soak in the views. Many reviews mention the lively music and the friendly company—sometimes the boat turns into a mini dance floor, which guests find a fun way to wind down after a day of exploring.

What’s Included and What to Know

Included: Snorkeling gear, local beer, white wine, iced tea, cola, Fanta, and water. These drinks help keep you refreshed as you bounce from caves to beaches.

Not included: Lunch, so packing a snack or light lunch might be a good idea if you’re hungry after the tour.

Meeting points vary based on your booking, so double-check your pickup location. The tour ends back at your starting point—convenient for planning your day afterward.

Flexibility is key: the captain might change the itinerary depending on weather conditions. For example, the order of visiting the Blue and Green Caves can switch if the sun’s position impacts visibility or safety.

What to bring: Swimwear, towel, sunscreen, and perhaps a waterproof phone case if you want to take underwater photos of the caves.
