Dubrovnik: Blue Cave & Lopud Beach Speedboat with Snorkeling

The Blue Cave glows turquoise only when you swim inside it

You swim into a glowing cave, snorkel through emerald grottoes, and spend the afternoon on a sandy island beach. All from a speedboat that picks you up in Dubrovnik and handles the navigation, gear, and drinks. The shallow water at Šunj makes it accessible even if you're not a strong swimmer, and the small-group format means you're never jostling for space in the caves.

The experience

The speedboat pulls away from Dubrovnik Old Town and the city walls drop behind you, Lovrijenac fortress rising 37 meters above the water on your right. Your skipper points out the legends carved into the stone as you cut across the Adriatic toward Koločep Island. The water shifts from deep blue to something almost unreal. That's where you're headed. The boat anchors about 20 meters from the Blue Cave entrance because the opening is too narrow for anything with a motor. You put on the snorkeling mask, check the fit, and slip into water so clear you can see straight down. Then you swim the last stretch and duck inside.

The cave is small, maybe the size of a room, and the light bouncing off the limestone walls and the seafloor makes the water glow like someone's lit it from underneath. You float there for a few minutes, just looking. The skipper stays with the boat, but floaters and noodles are on board if you need them. After the Blue Cave, the speedboat takes you to the Three Green Caves: two of them open for snorkeling, one a tunnel that cuts straight through the island. The emerald glow in those caves comes from the same trick of light and limestone, but it's different each time. You can choose to snorkel or just float and watch.

The final stop is Šunj Beach on Lopud Island, a kilometer of sand with water so shallow it extends 100 meters from shore, which means kids and anyone less confident in the water can walk out and still be fine. The speedboat drops you as close as regulations allow, then anchors offshore. You have free time to swim, sunbathe, or order a drink at the beach bar. Order something and you get a sunbed and umbrella thrown in. The whole tour runs in a small group, so it never feels crowded. If you're going between November and April, Šunj closes for the season, so the skipper adjusts the final stop to either Lopud village or Koločep village instead.

The boat returns you to your departure point in Dubrovnik Old Town, Cavtat, Mlini, or Srebreno: whichever one you left from. Snorkeling gear, life jackets, floaters, drinks, and the skipper's knowledge of the coast are all included. No separate fees for the caves or the beach.

What’s included

Your day includes hotel or town pickup (from Dubrovnik Old Town, Cavtat, Mlini, or Srebreno), a professional skipper and local guide, snorkeling masks and breathing tubes, life jackets and floaters, sparkling drinks and natural juices, and access to the Blue Cave, Three Green Caves, and Šunj Beach or an alternative village stop in winter months. If you order a drink at the beach bar, a sunbed and umbrella are complimentary.
