Kotor Bay: Private Blue Cave & Lady of the Rocks Boat Tour

Summary

Private boat across Kotor Bay to Blue Cave with swim stop and island church visit

You’ll cruise Kotor Bay by private boat with a local skipper, pausing for stories at Our Lady of the Rocks island before swimming inside Montenegro’s glowing Blue Cave. Expect cool breezes, quiet moments inside an island church, and laughter after your swim—all with gear provided and plenty of time to soak up those views.

What’s the experience like?

I didn’t really know what to expect from a “Kotor private boat tour” except, well, water and maybe a bit of sunburn. But as soon as we pulled away from the dock, the bay just felt different—quiet but not empty, if that makes sense. The skipper (Miloš) waved at some fishermen near Perast and pointed out these old stone houses tucked between olive trees. You could smell the sea mixed with something herbal—maybe wild sage? I kept thinking how time here doesn’t move like it does back home.

We stopped at Our Lady of the Rocks, which honestly looks like someone dropped a tiny church in the middle of nowhere. Miloš told us how locals built it up over centuries by sinking old ships loaded with rocks (he made it sound both heroic and slightly insane). Inside, there’s this hush—cool air, candle wax smell, and all these silver votives hanging everywhere. I tried to ask about one painting in clumsy Serbian; an older woman smiled and answered in English anyway. She said people still come here every year to add more stones. It’s weirdly moving.

The main event was swimming at the Blue Cave. We anchored outside—no motors allowed inside now, which makes it super peaceful. The water glows this unreal blue under your skin; I lost track of time floating there while someone on another boat sang softly in Montenegrin. My friend forgot her waterproof case but risked her phone anyway (she got lucky). When you climb back on board you’re salty and shivering but kind of giddy—I still think about that light flickering off everyone’s faces.

On the way back we passed Mamula Island (the fortress looks haunted) and slid past these old submarine tunnels carved into cliffs. Miloš told Cold War stories that sounded half-true, half-legend. The wind picked up a little so we huddled into our jackets, laughing about how none of us packed right for Montenegro weather in spring. Honestly, if you’re even half-curious about Kotor or just want a good swim spot with some history mixed in, this day trip is worth it—even if your hair ends up full of salt.
