Starting from a meeting point that may vary depending on your booking, the tour lasts around 30 minutes. The semi-submarine itself is a cheerful yellow vessel that stays afloat rather than diving, with its submerged cabin sitting 1.5 meters below the surface. One of the best parts? You can either stay inside in comfort or step out onto the deck to catch the sea breeze and enjoy the views.
Once the vessel reaches Redagara Bay, the highlight begins. The cabins are equipped with four large, tempered glass windows on each side, providing panoramic views of the underwater world. The cabin is air-conditioned, ensuring a pleasant environment for all ages, especially during the hot summer months. During the night tour, powerful LED lights illuminate the water, attracting fish and creating a mesmerizing glow—a hit with couples and photography enthusiasts.
While the semi-submarine doesn’t dive, the views beneath the surface are surprisingly vivid. As noted by reviewers, schools of fish and other marine creatures like sea urchins are common sights. One traveler even described it as “really nice what we saw,” highlighting the visual appeal. The ability to observe marine life from the comfort of a cabin is particularly appreciated by families with children or those who prefer not to snorkel or dive.
Beyond the underwater vistas, the tour offers scenic views of Krk’s coast, including the historic city walls, the famous cathedral, and the beautiful beaches. These sights are especially striking from the water, giving you a different perspective than from land.

The air-conditioned cabin ensures comfort, especially during hot days, and the semi-submarine’s stable design adds to the sense of security. While not suitable for those with claustrophobia, most travelers enjoy the cozy enclosure and the ability to step outside if they prefer.
The tour provides ample chances for photos, both from the deck with views of Krk’s shoreline and inside the cabin through the large windows. Night tours with the LED lights create a magical glow, perfect for capturing memorable shots.

This experience is ideal for families, couples, and solo travelers seeking a relaxed, visually stimulating activity that doesn’t require physical exertion or special skills. It’s especially suitable for those wanting a quick, memorable glimpse of underwater life and Krk’s scenic coastline.
