Dubrovnik Blue Cave & Lopud Beach Speedboat Tour

Summary

Swim Dubrovnik’s glowing caves then unwind on sandy Lopud

You’ll swim straight into Dubrovnik’s Blue Cave (yes, actually swimming), snorkel through glowing Green Caves with your local guide nearby, and stretch out on Lopud’s soft sands with a cold drink in hand. Expect laughter echoing off stone walls and maybe a little sunburn—these are memories that stick long after you’re dry.

What’s the experience like?

I didn’t expect the water to actually look that blue — you know how photos always exaggerate? But as soon as our guide Luka anchored near Koločep, I could see this weird electric glow under the surface. He handed out masks and laughed when I hesitated at the idea of swimming into a cave (“Don’t worry, it’s not haunted!”). The entrance was just a slit in the rock, barely wide enough for my shoulders, and inside everything turned this shimmering blue. It felt quiet, except for someone’s muffled laugh echoing off the stone. Honestly, it was colder than I thought but worth every goosebump.

After floating around in that neon world (and trying to keep my snorkel above water — harder than it looks), we climbed back onto the speedboat and zipped over to the Green Caves. Sunlight bounced off the walls, turning everything emerald. Luka pointed out some old graffiti from decades ago; apparently locals used to come here as teenagers. I tried swimming through one of the tunnels but chickened out halfway — someone else made it all the way and came up grinning like they’d won something big.

The last stop was Šunj Beach on Lopud Island, where we could finally just flop down on warm sand. There were these blue umbrellas lined up by a little bar — if you ordered a drink (I got something with way too much grappa), you got a free sunbed. The beach stretched so far out that even after wading forever, the water stayed knee-deep. It smelled like sunscreen and salt and fried fish from somewhere behind us. We all just lay there for a while, letting our towels get sandy and talking about which cave was best. On the ride back toward Dubrovnik’s city walls, I kept thinking about that weird blue light inside the cave — how it didn’t feel real at all.
