Kotor Bay: Blue Cave, Our Lady of the Rocks & Žanjice Beach Swim

Summary

Boat trip through Kotor Bay with Blue Cave swim and island stories

You’ll board a boat right on Kotor Bay, cruise past old villages and dramatic cliffs before stepping onto Our Lady of the Rocks island to hear local legends. Dive into the shimmering Blue Cave for a swim (it really does glow), then unwind at Žanjice Beach with time to just float or sunbathe before heading back — it’s all guided, relaxed, and surprisingly moving if you let it be.

What’s the experience like?

We’d barely left the dock in Kotor when I realized how much I underestimated this place. The water was glassy that morning — you could see every ripple from the boat’s wake as we moved past old fishing villages and those pale stone houses with laundry out front. Our skipper, Marko (he had that sunburned sailor look), pointed at a cluster of cypress trees and told us about his grandmother’s recipes for squid ink pasta. I tried to imagine growing up here, surrounded by mountains that just drop straight into the sea.

Our Lady of the Rocks was next — you actually step onto this tiny man-made island, which is wild when you think about it. There’s a church full of silver votives and paintings; Marko said locals still come to leave offerings for safe journeys. The air inside smelled like wax and old wood, and there was this hush even with tourists around. I didn’t expect to feel anything but honestly, it got under my skin a bit. We passed Perast after — all baroque palaces and narrow lanes — but just from the water this time.

The main thing everyone talks about is the Blue Cave. You only get there by boat; it’s just this opening in the rock but once you jump in (colder than I thought!), sunlight hits the white pebbles underneath and everything turns electric blue around you. Someone tried to film it but dropped their phone — thankfully those waterproof cases they hand out actually work. There was a lot of laughing and splashing, plus that salty mineral smell you only get in these parts of Montenegro.

On our way back we drifted past Mamula Island — Marko started telling us about its history as a prison during WWII but then switched mid-story to a joke about Montenegrin coffee habits (he claims nobody rushes anything here). Last stop was Žanjice Beach where people just sprawled out on towels or floated quietly for ages. I kept thinking about how light changes on the bay as afternoon rolls in… hard to describe unless you’re there yourself.
