If you’re visiting Krk and craving a unique way to see the sea, the Yellow Semi-Submarine Tour offers a charming, affordable experience that’s especially appealing if you’re curious about marine life or want a relaxed boat ride with a twist. We’ve read plenty of reviews and details, and it seems like a solid choice for travelers looking for a short, memorable adventure without the hefty price tag.
Two things that really stand out about this tour are its fantastic views of Krk’s historic city walls and cathedral from the water and the opportunity to observe schools of fish through the underwater cabin windows. Plus, the option to choose between a lively day fish-feeding experience or a romantic night cruise illuminated with LED lights adds a nice touch of flexibility. However, one thing to keep in mind is that the semi-submarine doesn’t actually dive — the cabin stays submerged just 1.5 meters below the surface — so if you’re expecting a true underwater exploration, this might fall short. Still, it’s a charming, family-friendly outing that suits anyone interested in a gentle, scenic adventure on the water.

What to Expect from the Krk Yellow Semi-Submarine Tour

This tour lasts about 30 minutes, which makes it perfect if you’re short on time but still want to squeeze in something a little different. The vessel is called a semi-submarine because it doesn’t dive — instead, it has a submerged cabin just 1.5 meters below the surface, with the rest of the craft remaining above water. This design means you get the feel of being underwater while still enjoying fresh air and open views.
You’ll board a bright yellow semi-submarine, which is intended to give a bit of a playful, eye-catching vibe. The underwater cabin features four large tempered glass windows on each side, giving you a panoramic view of what’s happening underneath. The cabin is air-conditioned, a thoughtful touch for hot summer days or evenings, ensuring you stay comfortable while marveling at the marine environment.

Choosing Your Experience: Day vs Night
One of the nice features of this tour is its flexibility. During the day, you can opt for the fish-feeding experience, which seems to be a hit with both kids and adults alike. When the boat reaches Redagara Bay, you’ll enter the underwater cabin and see schools of colorful fish, sea urchins, and other creatures. It’s a pretty straightforward but charming way to get a peek into underwater life, especially if you’re not into diving or snorkeling.
Alternatively, the night tour offers a different perspective. The LED lights inside the cabin illuminate the water around you, attracting marine animals and creating a magical, almost otherworldly atmosphere. It’s perfect for couples or anyone who wants a more romantic, peaceful vibe.
The Views and the Surroundings
From the deck, you’ll get lovely views of Krk’s historic city walls and its famous cathedral, along with the surrounding beaches and coastlines. The tour’s route around Redagara Bay offers a scenic backdrop that’s especially photogenic. Several reviews praise the staff and captain’s friendliness, which helps make the experience even more enjoyable.
The Experience Itself: What It’s Like

On board, you’ll find a small group, which helps keep the atmosphere relaxed and friendly. The guides and crew are noted for being knowledgeable, kind, and attentive — a real plus if you prefer a more personal touch. As one review puts it, “the leader was kind,” and another mentions how the captain even let a child stand at the helm for a moment, adding a touch of fun.
The duration of 30 minutes means it’s more of a quick highlight than a full-day adventure. Nonetheless, many reviews mention it being “better than expected,” especially considering the price. The views of the coast, the city, and the marine life are often described as “spectacular” or “really nice,” making it a worthwhile little outing.

Also, it’s not suitable for those with claustrophobia, given the enclosed nature of the cabin.
Practical Tips
- Price-wise, it’s a steal at around $18, especially considering the views and marine life sightings you get. It’s a simple, straightforward activity, but great for a quick break or a family outing.
- Booking is flexible — you can reserve now and pay later, making it easier to fit into your travel plans.
- Timing depends on your preference: daytime offers bright, lively scenes, while nighttime transforms the experience into something more peaceful and luminous.
