Blue Cave, Submarine Base, 3 Hours
Kotor: Blue Cave, Submarine Base, and Lady of the Rocks Tour runs through Aquaholic Speedboat Tours Kotor. Rated 4.8 across 5,099 reviews. Runs 3 hours. From $43.
Aquaholic Speedboat Tours leads on volume with a 4.8 rating across 5099 reviews, and MontenegroGlobe matches that score on 1651. The 4-hour Best from Kotor trip tops the table at 4.9 from 343 reviews, though no operator is named on that listing. Every shared tour here scores 4.7 or higher, so the rating gap between boats is thin and price or timing can settle it.
All nine tours chase the same headline stops, so the real differences come down to duration and pace. Two hours is plenty for Perast and Our Lady of the Rocks with Montenegro Submarine and Speed Boat Tours at $33. Three hours suits swimmers who want time in the water at the Blue Cave mouth, while the 4-hour Best from Kotor trip adds proper time ashore in Perast's old town.

Check availability →Read the inclusions before you book. Some tickets fold the Our Lady of the Rocks landing into the price and others leave it to pay at the jetty, and when swell runs high the Blue Cave can shut to boats, in which case skippers linger elsewhere along the bay. Morning departures tend to give the calmest water for the cave swim, and all nine shared tours here cancel free of charge.
Most shared speedboat trips from Kotor follow the same arc: out past Mamula, whose fortress prison dates to 1853, a swim stop at the Blue Cave, and time at Our Lady of the Rocks near Perast. Under the 2026 rule, boats anchor outside the cave and guests swim in, so bring something you can swim in. Three hours is the standard length, and every tour on this page allows free cancellation.
Choice mostly comes down to pace and price. The shortest option, a two-hour speedboat run to Perast and Our Lady of the Rocks, starts at $33, while the full three-hour cave circuits begin around $38. A four-hour version adds real swim time and old town wandering in Perast. Operators cluster near the Port of Kotor; one departure point sits roughly 200 m from the Main Gate of the Old Town (see Walk From Cruise Port).
