Kotor: Blue Cave Speedboat Tour & Perast Stop Small Group

Summary

Swim in glowing blue water, pass old fortresses and wander Perast’s quiet streets

You’ll ride a modern speedboat from Kotor with a small group and local skipper, swim near the glowing Blue Cave waters, slip into hidden submarine tunnels on Luštica Peninsula, and wander Perast’s peaceful lanes with views of Our Lady of the Rocks island. Expect laughter, salt air—and moments that stay with you long after you dry off.

What’s the experience like?

Ever wondered if that electric-blue water in photos is real? I did too, until we left Kotor’s marina early one morning—just twelve of us, plus Luka, our captain who grew up around these bays. The boat felt new and clean (I grabbed a coffee from their office first), and as we zipped out past the city walls, the air had that salty snap that wakes you up better than espresso. Luka pointed out Mamula Island in the distance—a round stone fortress that looked like it belonged in some old spy movie. He told us it was once a prison, but now just sits there, half-wild with seabirds circling. I tried to imagine what it must’ve sounded like inside on stormy nights.

The main thing everyone talks about is the Blue Cave. But here’s the thing—they can’t take boats all the way inside right now (some law or something), so we stopped just outside. Still, when I slid into the water—cold at first, then perfect—the light really did turn everything this weird shimmering blue. It was quieter than I expected; just us laughing and splashing around for maybe twenty minutes. One guy tried to do a handstand underwater and totally failed—made us all laugh. The water tasted faintly metallic if you got any in your mouth (not recommended). Afterward, we wrapped up in towels and Luka handed out raincoats for anyone who wanted them—Montenegro weather likes to keep you guessing.

We cruised by some old submarine tunnels carved into Luštica Peninsula—dark mouths in the rock where Yugoslav submarines used to hide. Luka steered us right inside one for a minute; it echoed weirdly and smelled damp and stony. Then back out into sunlight again, passing Porto Novi’s fancy new buildings before heading toward Perast. That town feels frozen in time: narrow stone alleys, sleepy cats on windowsills, and those two little islands offshore—Our Lady of the Rocks and St George—just floating there like they’re waiting for something to happen.

We got twenty minutes to wander Perast on our own; I bought an ice cream from an old lady who didn’t speak English but smiled anyway when I fumbled my coins. The bells from a church tower drifted across the bay while we sat on a low wall watching boats come and go. Heading back to Kotor, everyone was quieter—maybe tired or just letting it all sink in. I still think about that blue light under the water sometimes; it doesn’t look real until you’re right there inside it.
