You’ll start early from Dubrovnik by private speedboat, swimming through the glowing Blue Cave on Koločep island before exploring hidden Green Caves nearby. Relax on Lopud’s sandy Šunj beach with a drink in hand and time to unwind beneath pine trees—this day trip leaves you with memories of laughter, saltwater and that unreal blue glow.
I didn’t think I’d ever see water that blue. We met our skipper at Lapadska obala, a little before 8:30 — I was still half-awake, honestly, but the marina had this salty smell and a few sleepy cats wandering around. The boat felt just right for our group (there were six of us), and once we left Dubrovnik behind, the wind started to wake everyone up. Our guide — Mario? Marko? I never quite caught it — handed me a cold bottle of water and pointed out Koločep ahead. He said something about the light in the Blue Cave being “like nowhere else,” which sounded dramatic until we actually swam inside.
The Blue Cave is tucked into the south side of Koločep island. You have to duck down to get in — my friend nearly lost her snorkel mask from laughing so hard when she bumped her head (she’s fine). Inside, it’s this weird calm: the water glows blue under you, brighter than anything outside. It felt almost fake, like someone turned up the saturation. The sea was cool but not cold; I could hear our voices echoing off the stone walls. After maybe half an hour there (time gets slippery in places like that), we zipped over to these smaller Green Caves nearby. The color shift is real — more greenish light filtering through underwater cracks. Some of us tried jumping off rocks; I chickened out but cheered anyway.
By late morning we reached Lopud island and Šunj beach. If you’re expecting pebbles like most Croatian beaches, this one surprises you — soft sand underfoot, shallow warm water stretching out forever. There’s a bar tucked into some pine trees where we grabbed white wine and just sat around in wet swimsuits, watching kids build sandcastles and locals chatting in bursts of fast Croatian. It was quiet except for cicadas buzzing somewhere above us. I kept thinking how different everything felt compared to Dubrovnik’s busy streets — slower, softer somehow.
We had drinks included (beer for some, juice for others), which made it easy to just sit back and let time drift a bit before heading back toward the city. If you’re curious about a private Blue Cave tour from Dubrovnik but don’t want crowds or megaphone guides yelling over each other… well, this felt pretty much perfect for us. And yeah, I still think about that blue light sometimes when I close my eyes at night.
