Abandoned Submarine Tunnels

Montenegro’s submarine tunnels, or bunkers, are channels dug out of cliff walls in the Bay of Kotor (on the northern coast of the Luštica Peninsula, near the village of Rose) built by the Yugoslav Army for the purpose of concealing submarines and small warships from satellites or spy planes.

Three such tunnels were constructed, intended as protection from air raids. A submarine would have entered a tunnel while submerged and surface completely once inside. With an average depth of about 90 feet and a maximum depth of over 200 feet, the Bay of Kotor offered an ideal location to such hide vessels of marine warfare.

Each tunnel is cut about 300 feet deep into the cliff side with a water depth of around 30 feet. Once camouflaged with phony rocks which have since deteriorated, the tunnel entrances are now easy to see from a distance. They were abandoned around the time of the collapse of the Warsaw Pact, being too small for today's larger submarines.

Boat operators from multiple locations along the Bay of Kotor offer boat trips to view, and possibly swim in, several features including these tunnels. Smaller your boats are able to enter the tunnel, and depending on the type of tour you take it may possible to swim inside or walk along the sides.
