Montenegro Bay of Kotor Speedboat Tour with Blue Cave and Submarine Base
This guided speedboat tour departs from Kotor, ideal for history and nature enthusiasts seeking a scenic coastal experience.
Description
The tour begins with a panoramic cruise past Perast, a baroque town known for its Venetian architecture and twin islands, St. George and Our Lady of the Rocks.
Stop for 20 minutes at Our Lady of the Rocks to explore the 15th-century church and maritime museum. Note: swimwear is not permitted here; both men and women must wear clothing covering shoulders and modest-length shorts, skirts, or dresses.
Next, enter a secret Yugoslav-era submarine tunnel carved into the cliffs. Your guide will share Cold War stories from this historical military site.
Continue cruising past Mamula Island, a fortress-turned-prison used during WWII, noted for its eerie history and dramatic setting.
The final highlight is the Blue Cave. Sunlight reflecting off the white seabed creates its distinctive glowing turquoise water. From May 21, boats no longer enter the cave; guests swim from the entrance during a 30-minute stop to fully experience this natural phenomenon.
Throughout the trip, the local skipper and guide provide stories, music, and insights into the history and legends of the Bay of Kotor.
