Blue cave, Mamula island, Submarine tunnels and Our lady of the Rocks (3h)

A Fun, Informative 3-Hour Boat Tour of Kotor Bay

When we think about exploring Kotor Bay, Montenegro, there’s no better way than hopping onto a speedboat adventure that covers some of its most iconic sights. For just around $41 per person, Sea Dog Speed Boat Tours offers a compact, reasonably priced trip that’s packed with natural beauty, history, and some playful swimming. The tour’s highlights include the dazzling Blue Cave, the historic Mamula Island, the intriguing WWII submarine tunnels, and the impressive Our Lady of the Rocks.

One of the things we love about this experience is the way it balances scenic beauty with history and fun. The boat ride itself is a highlight — with knowledgeable guides who share stories and interesting facts, plus the chance to swim near the Blue Cave. Another aspect we appreciate is the flexibility to bring your own food and drinks, turning the trip into a personalized outing that fits your mood.

Of course, no trip is perfect for everyone. Some reviews mention that the Blue Cave might be underwhelming if you’ve seen many similar caves elsewhere, and the bumpy boat ride can be a challenge for the seasick or those preferring calmer waters. This tour is best suited for travelers who enjoy active, scenic outings, and who are comfortable on a boat for about three hours.

If you’re after a cost-effective, authentic experience that combines stunning views with a touch of local history, this tour makes a solid choice. It’s also ideal for cruise passengers or those short on time but eager to see the highlights of Kotor Bay in a fun, social setting.

The Experience in Detail

Starting Point and Duration

The tour begins at Park Slobode in Kotor, a central location easy to reach whether you’re coming from a cruise, hotel, or town center. It lasts approximately three hours, making it a perfect half-day outing that won’t leave you exhausted. The small group size (up to 20) means you’re likely to feel more like a guest than a number, with opportunities to ask questions and enjoy the scenery at your own pace.

The Scenic Bay of Kotor

We love the way the boat glides smoothly along the serene waters of Kotor Bay, revealing a coastline dotted with ancient fishing villages and lush vegetation. The views are striking — rugged mountains frame the bay, while tiny settlements cling to the shoreline. It’s a landscape that feels both untouched and steeped in history, making it ideal for photography and just soaking in the atmosphere.

The Blue Cave: Nature’s Light Show

Arriving at the Blue Cave is always a highlight. Accessible via two entrances — a wide, low opening and a narrow, tall one — it’s a natural wonder created by waves crashing over thousands of years. Inside, the play of sunlight creates a stunning blue glow, which is especially captivating for divers and snorkelers.

While some reviews mention that the Blue Cave may not be as “blue” as expected, most agree it’s worth the visit. The water inside the cave provides excellent photo opportunities, both above and beneath the surface. The short 20-minute stop allows plenty of time to take pictures and enjoy the atmosphere without feeling rushed.

Mamula Island: A Fortress with a Past

Next, we pass by Mamula Island, a small, circular islet that once served as a prison (built in 1853). The island’s fortifications and abandoned structures evoke a sense of its military history, which adds a layer of intrigue for history buffs. From the boat, you can admire its fascinating architecture and imagine what life must have been like for inmates.

Many reviews appreciate this stop for giving a glimpse into Montenegro’s military past, and the scenic views around Mamula make for great photos. It’s a quick look, but one that’s memorable.

WWII Submarine Tunnels

The tour then continues to one of the three submarine tunnels used during WWII. These tunnels represent a fascinating piece of modern history, where submarines were hidden and repaired. Seeing these hidden pathways from the water offers a unique perspective that land-based tours simply can’t provide.

Some travelers find the tunnels particularly interesting, and others note that it’s a quick visit, but still a worthwhile stop to connect the natural scenery with Montenegro’s wartime past.

Our Lady of the Rocks: A Man-Made Wonder

The final highlight is Our Lady of the Rocks, an artificial island built from rocks and old ships. The church, decorated with ex-voto offerings, is the main attraction, and there’s also a small museum and gift shop. You will have about 20 minutes here to explore and take in the spectacular views of the bay.

While the entrance fee is modest (around 1.5 euros), many visitors find the story of its creation and religious significance adds depth to the visit. The island’s visual contrast — a tiny church atop a craggy outcrop — makes it one of the most photographed spots in the bay.

What You’ll Experience on the Boat

The boat itself is described as comfortable, with options to play your own music and bring snacks or drinks — a nice touch that adds to the relaxed, personalized vibe. The crew, often praised as friendly and knowledgeable, provides interesting commentary on each sight.

Some reviews mention the bumpy ride due to weather conditions, so if you’re prone to seasickness, bring seasick pills or consider that the trip could get a bit choppy. The guide’s fast-paced narration is a common theme — if you love learning on-the-go, you’ll enjoy the lively commentary.

Swimming and Snorkeling

One of the most praised aspects is the opportunity to swim near the Blue Cave and in the bay. Many travelers highlight how fun it is to jump into the clear waters and even swim through small caves. The water tends to be refreshingly cool, perfect for a quick dip on a warm day.

The Music and Atmosphere

A standout feature is the skipper’s playlist, which many reviews rave about. The music, combined with the beautiful scenery and friendly crew, makes the whole experience feel like a luxurious, yet laid-back outing.

Who Should Book This Tour?

This 3-hour boat tour is best suited for travelers who want to see the highlights of Kotor Bay without spending a full day. It’s perfect for cruise passengers, couples, families, and small groups who enjoy a bit of adventure combined with scenic beauty.

While some reviews mention that the Blue Cave may not always live up to expectations, most agree that the overall experience is memorable and fun. If you’re comfortable on a boat and enjoy a mix of nature, history, and swimming, this trip will suit you well.

Final Thoughts: Is This the Tour for You?

If you’re looking for a cost-effective, well-organized, and visually stunning trip, this tour offers excellent value. The small group size and personal touches like bringing your own music or snacks make it an enjoyable, flexible experience. The variety of stops — from natural caves to historic islands — means you’ll leave with a broad appreciation for Kotor Bay.

However, keep in mind that weather can influence your experience, especially the Blue Cave visit, and the bumpy boat ride might not be suitable for everyone. It’s best suited for those who enjoy active sightseeing and are okay with a bit of choppiness.

All in all, this tour delivers a great mix of scenery, history, and fun at a reasonable price — a perfect way to spend part of your day in Montenegro.
