Dubrovnik Blue Cave Tour: 5-Hour Sea Safari & Šunj Beach

Summary

Swim Dubrovnik’s caves then relax longer on sandy Šunj Beach

You’ll feel salt on your skin as you swim through Dubrovnik’s Blue Cave with a small group and local guide. Snorkel among fish, laugh with fellow travelers, and stretch out on sandy Šunj Beach with a cold drink in hand. It’s five hours of sun-warmed adventure—enough time to actually relax before heading back.

What’s the experience like?

I didn’t expect the water to feel that cold—like, really cold—when I slid off the boat near the first cave. Our guide, Marko, just grinned and said “You’ll get used to it!” He was right. After a few seconds my skin stopped complaining and I started noticing everything else: the way sunlight bounced inside the Blue Cave, turning everyone’s faces a bit blue too. There was this salty smell mixed with sunscreen and something sweet from someone’s soda can. I kept thinking how weirdly quiet it got once we ducked inside, like the sea swallowed up all the usual summer noise.

We hopped between islands—three in total, which sounded ambitious but somehow felt easy. Marko always checked if everyone was okay before moving on (he even helped this older couple down the ladder when they hesitated). At one of the Green Caves he handed me a snorkel mask and pointed out where to look for these tiny silver fish darting around. I tried to say “thank you” in Croatian but probably butchered it; he just laughed and said “close enough.” The main keyword here is definitely “Blue Cave tour Dubrovnik”—but honestly, it’s not just about ticking off caves. It’s about those small moments with people you’ve only just met.

The last stop was Sandy Beach Šunj on Lopud Island. We got more time there than I expected—almost an hour to just flop down on warm sand or float in shallow water while some folks sipped beer from plastic cups (included in the tour, by the way). There were kids building lopsided sandcastles and someone playing music softly from their phone. I lay back and watched clouds drift over Dubrovnik’s outline far off across the water. Still think about that view sometimes, especially when I’m stuck in city traffic now.
