A Practical Overview of the Semi-Submarine Tour

This activity takes place at the port of Krk, where you’ll board a bright red semi-submarine that looks like a small submarine but stays afloat on the surface. Unlike traditional boats, this vessel is specifically designed for viewing underwater life through large windows while remaining dry and safe. It’s a simple concept, but the appeal is undeniable—imagine cruising along while peering into the ocean below.

The duration is just about 30 minutes, which makes it an easy addition to your day without overcommitting. Check the availability ahead of time, as starting times vary, and ensure you arrive at the meeting point in front of the Hotel Marina, located at the waterfront. If you’re arriving by bus, a short walk from the Krk bus station will land you right at the bright red vessel.

What to Expect During the Tour

Once aboard, you’ll start with a scenic cruise from the port, offering views of Krk’s historic walls, stone houses with red roofs, and churches that define the town’s skyline. These picturesque vistas alone are worth the trip, especially for those who love classic Mediterranean scenery.

Soon, you’ll descend below deck through large windows to explore the underwater environment. Here, you might see fish swimming in their natural habitats, along with other marine creatures like sea urchins. The reviews confirm that viewers often see a variety of species, making this a fun and educational experience for kids and adults alike.

The semi-submarine’s deck offers an open-air experience where you can enjoy the breeze and panoramic views, perfect for snapping photos or just soaking in the scenery. Many reviewers mention how the experience provides a good balance of fun and relaxation, with one noting, “The whole family enjoyed that,” and another praising the chance to see lots of fish.

The experience is designed to be safe and accessible, especially since it doesn’t involve swimming or diving gear. Kids can explore the underwater world confidently, and parents appreciate the secure environment.
