Travelers

The hull nosed into a shadow at the base of a knife-edged cliff, and sunlight sliced through the narrow entrance to light the water like spilled cobalt paint. For three hours the sea does the guiding: it draws you through Luštica’s carved limestone, past concrete ribs of wartime submarine pens, and around the squat silhouette of Mamula Island where stone once meant confinement.

Adventure Tips

Swim-ready clothing

Wear your swimsuit under your clothes for a quick jump into the cave; drying off is easier if you have a lightweight towel and a change of clothes onboard.

Sun protection

Bring reef-safe sunscreen and a hat—the Bay’s reflective water doubles UV exposure during the midday stop.

Secure valuables

Use a small waterproof pouch for your phone and passport—crew will advise where to stow items during stops and when entering the water.

Check sea conditions

If you’re prone to seasickness, take medication before departure and sit toward the center of the boat where motion is reduced.

History

Conservation

The Bay of Kotor is ecologically sensitive; choose operators who limit anchoring in seagrass beds and encourage reef-safe sunscreen and responsible swimming.
