What to expect

If you’re visiting Montenegro, don’t miss the famous Blue Cave—one of the country’s most stunning natural wonders. Located near the entrance to the Bay of Kotor, the cave is known for its glowing, crystal-blue water. Sunlight reflects through an underwater opening, making the sea appear lit from below. This isn’t just a visual spectacle—swimming is allowed, so you can dive in and feel the magic for yourself.

After exploring the Blue Cave, we’ll head to a fascinating piece of Cold War history: the submarine tunnel, located just 700 meters from the village of Rose. Built by the Yugoslav Navy in the 1970s, this hidden naval facility could house two submarines and served as a concealed shelter from aerial surveillance and attacks. In the early 2000s, it was even used briefly as a unique venue for the Entrance electronic music festival.

We’ll also enjoy panoramic views of Mamula islet, home to the infamous Mamula Fortress. Constructed by the Austrians in the 1850s atop older defensive structures, it formed part of the first line of defense for the bay, alongside Fort Arza and Cape Oštro. Though it was soon outdated by modern weaponry, the fort sustained damage during WWI and took on a darker role as a prison. It was first used in 1916 to hold Montenegrin officers, and later imprisoned Boka sailors—then part of the Austro-Hungarian Navy—who had rebelled against the empire. During WWII, Mamula was used by Italian fascists as a prison camp until the end of the war.

Today, the fortress has been transformed into a luxury hotel, though its complex history remains part of its identity.
