Dubrovnik Blue & Green Cave Tour with Sunj Beach Stop

Summary

Speedboat swim through Dubrovnik caves and Sunj beach escape

You’ll slip into Dubrovnik’s glowing Blue Cave before crowds arrive, snorkel through green-lit water off Kolocep Island, then unwind at sandy Sunj Beach with drinks included. With a local skipper guiding your small group by speedboat, expect laughter, salty swims, and plenty of time to soak up Croatia’s quieter side.

What’s the experience like?

“You see that shimmer? That’s not a filter — it’s real,” our skipper Luka grinned as we drifted up to the Blue Cave off Kolocep. He was right. It was early, the water glassy and cold against my toes, and I felt a weird mix of nerves and excitement before slipping in. The cave swallowed us in blue light — not bright, more like someone turned down the world outside. I could hear the echo of my own splash. Someone behind me laughed, maybe from relief or just because it was so strange to be floating in a place that glowed like that.

We didn’t stay long (maybe 40 minutes?), but it was enough. Luka handed out snorkels for the next stop — three smaller green caves, still on Kolocep. The sea here looked almost fake, greenish and clear enough to spot little silver fish darting around rocks. I tried to say “thank you” in Croatian when Luka pointed out a starfish, but he just smiled and said, “No worries, English is fine.” The salt stung my lips but I barely noticed; too busy watching sunlight flicker underwater. There was beer and white wine on board for later (adults only), but honestly I stuck with water after swallowing half the Adriatic by accident.

Sunj Beach on Lopud was our last stretch — about an hour and forty minutes to just sprawl out or wander under pine trees. There’s a bar tucked into the woods where the shade feels like a reward after all that salt and sun. Some folks ordered lunch at one of the restaurants; I just lay back in the sand and let my hair dry crunchy from the sea. The group was small enough that nobody felt rushed or lost in a crowd, which I didn’t realize would matter so much until we got there.

I keep thinking about that blue glow inside the cave — how quiet it felt compared to Dubrovnik’s old town crowds. If you’re looking for something easy but real near Dubrovnik, this day trip is one of those things that lingers longer than you expect.
