The Blue Cave tour from Kotor is a 3-hour speedboat trip from Park Slobode pier to the Blue Cave (Plava Špilja) on the Luštica peninsula, about 45–60 minutes away, with a 30-minute swim inside the cave. The route also stops at Our Lady of the Rocks and passes the submarine tunnels, Mamula Island and Perast. In 2026 it costs €300 per boat as a private tour (1–6 guests) or €50 per adult on the shared group tour.
The Blue Cave is a sea cave on the Adriatic coast of Luštica that can only be reached by boat. Its turquoise glow comes from sunlight entering through a submerged opening, and the light is strongest between about 9:00 AM and 12:00 PM — so captains time departures to reach the cave in that window. On calm days guests swim freely inside; swim-in access always depends on the sea conditions of the day. By law, boats may no longer stop inside the cave, so the captain anchors at the closest permitted point outside the entrance and you swim in from there.
Boats leave Park Slobode, cross the inner bay past Perast and through the Verige strait, then exit into the open Adriatic near Herceg Novi and follow the Luštica coast to the cave. The return usually includes a stop at Our Lady of the Rocks.
Book a morning departure (9:00–11:00 AM) for the best light inside the cave, and a weekday if you prefer fewer boats. The season runs from April to October; the water is warmest for swimming from late May to September.
About 45–60 minutes by speedboat from Kotor Old Town, depending on sea conditions.
€300 per boat for the 3-hour private tour (1–6 guests; €360 for 7–8 and €440 for 9–10 guests), or €50 per adult and €30 per child aged 3–10 on the group tour (2026 prices).
Yes. The 3-hour Blue Cave & Our Lady group tour includes a 30-minute swim in the Blue Cave, a stop at Our Lady of the Rocks and photo stops at Mamula and Perast, with 10–12 passengers at most. Infants aged 0–2 are not accepted on group tours. The 4-hour Blue Cave & Perast group tour (Tour 9, €60 per adult) also swims at the Blue Cave and adds extra swimming stops and a longer stop in Perast, without Our Lady of the Rocks.
A morning departure between 9:00 and 11:00 AM gives the best light inside the cave; by noon the angle of the light starts to change.
Private speedboat from €300 per boat or group tour from €50 per adult. Daily departures from Kotor Old Town.
