At the exit from the Bay of Kotor into the open sea — two sites that few people understand from the water. Tunnels cut into the rocks under Luštica, where Yugoslav submarines once docked. And the Mamula fortress in the strait — an Austro-Hungarian structure from 1853 that became an Italian concentration camp in WWII and a luxury hotel in 2023. Both are part of the route to the Blue Cave. Most tourist boats pass without comment. Guests interested in history usually ask us to slow down.
"These walls aren't a tourist attraction — they're a reminder that the bay wasn't always just a beach. Military bases stood here, prisons, and you can still see the marks. If you want to understand Montenegro on a deeper level — it's worth a stop." — Captain Alexey
Lora submarine docks
On the southern side of the Luštica peninsula, in an area called Lora. This was a former naval base of Yugoslavia — built in the 1960s, in use until 1992. What was there: the base served the submarine fleet of the Yugoslav People\'s Army. The tunnels were cut straight into the rock — you enter on a small boat and have 50 metres of mountain over you. That protected the subs from a nuclear strike. The tunnels are wide enough to turn around inside. What\'s there now: abandoned since 1992, after Yugoslavia\'s collapse. The tunnels are open from the sea, you can approach close. You can\'t go inside — it\'s a restricted area (private or military, not entirely clear). From the water you see the entrances — four large arches in the rock, about 15 metres tall each. How we view it: we cruise along the shore at 50-100 metres, slow the speed. The captain narrates. For photos — a couple of points, takes about five minutes. It\'s not a "stop", it\'s a moment on the route to the cave. Abandoned military engineering in the rocks is a rare sight on standard tourist routes.
Mamula fortress
A small island in the strait between Luštica (Montenegro) and Prevlaka (Croatia), right at the exit to the open sea. What it was: 1853 — built by Austro-Hungarians, used to defend the entrance to the bay. Seventy cannons. 1942-1943 — Italian-occupied, used as a concentration camp for Montenegrin and Croatian partisans. Estimates range from 100 to 130 prisoners died there. 1945-1990s — Yugoslav military facility. 2000s — abandoned. 2023 — opens as Mamula Island Resort, €15 million reconstruction. What\'s there now: a luxury hotel, minimum €1,500 per night. Inside — the reconstructed fortress with modern interiors. Pier for guests, restaurant, spa. Can you go ashore: only if you\'re a hotel guest. From the yacht, photo-stop, circle around (about 15-20 minutes for a full loop), view the bastions from the sea. What you see from the water: old stone walls, bastions, dark window cavities, now with the white umbrellas of the hotel over them. The contrast between medieval defence and modern luxury is photogenic. Locals don\'t love it.
What guidebooks write vs what locals say
Guidebooks write "Austro-Hungarian fortress" and sometimes mention the Italian camp as a footnote. In the villages around — a different memory. Luštica families remember the names of those who died there. The 2023 hotel opening was met with protests — locals feel a place with this history shouldn\'t become entertainment for the wealthy. It\'s a complicated point. We don\'t comment on politics, but if guests are interested — we tell both sides. The history matters more than the photo.
How it fits into the route
All three sites (docks + Mamula + Blue Cave) are on the same trajectory — southwest of Tivat. Standard cave route: 9:00 — depart Porto Montenegro; 9:45 — pass along Luštica, by the submarine docks (5-7 minutes slowing down for photos); 10:30 — photo stop at Mamula (15-20 minutes around); 11:00-12:30 — Blue Cave in the light window; 13:00 — lunch in Rybarsko Selo or Fort Rose; 14:30+ — back. If your 8-hour charter includes the cave — the docks and Mamula are built in. If you want a deeper history focus — that\'s a 6-hour charter without the cave, focused on the fortress and the fjord with historical stops.
What\'s not usually written
The submarine docks are an empty base. Not an "open museum", not a "historical site for tourists". They\'re abandoned tunnels in the mountains. Without a captain who knows how to narrate, you just see black arches in the rock. With a captain — you hear the context: how Tito\'s navy used the bay, why here, what it defended. Mamula in 2026 is a contested place. When the hotel was being built, there were protests in Luštica and Herceg Novi. They\'ve quieted, but if you talk to a local — don\'t be too enthusiastic about the "beautiful hotel". It\'s a sore subject. And: not all our guests care about history. Some came to swim, not for lectures. In that case we pass the docks and Mamula without commentary — just cruise by. Tell us at booking what level you\'re comfortable with.
When the Mamula stop works best
For photos — morning 9:30-10:30 or sunset 18:00-19:00. Morning light from the east hits the bastions well. Evening — golden glow on the old walls. To avoid crossing paths with hotel guests and their tenders — better a weekday, not the weekend.
