Private Blue Cave boat tour from Kotor: Your own speedboat

The submarine tunnels are still there, carved into the cliffs where Yugoslav boats once hid.

A private speedboat tour from Kotor through the Bay of Kotor, Blue Cave, Perast and Mamula Island with a professional English-speaking skipper and no other groups aboard. Swim in the Blue Cave's glowing water, cruise past the 19th-century Mamula fortress, visit the artificial island of Our Lady of the Rocks with its Baroque church, and explore hidden submarine tunnels along the coast. The boat is yours alone for three and a half hours, with complimentary water, soft drinks, and onboard facilities.

The experience

What makes this tour different is the boat itself: you're not sharing it with strangers or waiting for other groups to board. The speedboat leaves Kotor with your party only, piloted by a skipper with over 30 years of local knowledge. That means the pace is yours: linger at the Blue Cave if the light is right, or move on when you're ready. The route covers the Bay of Kotor's major stops in a single morning or afternoon, but without the fixed schedule that forces you through each one at the same speed as everyone else.

The Blue Cave is the centerpiece: a single beam of light transforms the water inside into a glowing blue that photographs don't quite capture. You swim there, not just look from a distance. Nearby, Mamula Island rises from the sea as a 19th-century fortress, dramatic enough to feel like a film set. Our Lady of the Rocks, an artificial island built over centuries by sailors placing rocks after safe voyages, holds a Baroque church from 1632 with a museum of nautical relics and votive tablets left by thankful crews. Perast, visible as you pass, shows off its stone Baroque architecture along the shoreline. The hidden submarine tunnels, Yugoslav-era passages carved into the cliffs, are the surprise most travelers don't expect: you glide into them and feel the echo of history.

Onboard, the boat carries everything you need: a shower, a restroom, a fridge, bottled water and soft drinks. The skipper speaks English and knows which coves stay quiet and which routes catch the best light at different times of day. Three and a half hours covers the cruise, the stops, and the swim time without rushing.

Top questions

What happens if it rains?

It may be canceled due to bad weather. If that happens, you're offered another date or a refund. Free cancellation up to 24 h before the start.

Can we actually swim in the Blue Cave, or do we just look at it from the boat?

The Blue Cave is a swimming stop, not a viewing-only site. You enter the water inside the cave itself, where the light creates the glowing blue effect. Bring a swimsuit and be ready to get in.

What is Our Lady of the Rocks and why is it artificial?

Our Lady of the Rocks is an island built over centuries by a maritime tradition: sailors placed a rock in the bay after each successful voyage, and the ritual eventually formed an island. A Baroque church was built there in 1632 and now holds a museum of paintings, artifacts and votive tablets left by seafarers. Entry to the church costs €2–€3 and is optional.

Are we really going into submarine tunnels?

Yes. The hidden submarine tunnels are carved into the coastal cliffs and were used by Yugoslav submarines during the Cold War. The speedboat glides into these passages so you can see them up close. It's one of the most unusual stops on the route.

How long do we spend at each place?

The itinerary is flexible because the boat is private. You have roughly 90 minutes at the Blue Cave area to swim and explore, and you pass the other sites (Mamula Island, Perast, Our Lady of the Rocks) as part of the cruise. The skipper can adjust timing based on what interests your group most.

What's included on the boat?

Bottled water, soft drinks, and access to the onboard shower and restroom are included. The skipper is English-speaking and professional. Everything needed for the tour is on board. You bring your swimsuit and sunscreen.
