Hunt for dolphins alongside the researchers who study them

You board a boat with MareTerra marine biologists and search for bottlenose dolphins in Alghero's protected gulf waters, with an 80% chance of spotting them. After observing how researchers identify and track individual dolphins, you snorkel in the same area with a certified guide who stays alongside you. The boat's low-noise engines and strict approach protocols minimize disturbance to wildlife. Masks, fins, and species identification materials are included; just send your shoe size after booking.

The Experience

You're standing on the deck of a boat that's about to leave the harbor, and the marine biologist next to you casually mentions they've spotted dolphins on seven out of the last ten trips. That 80% sighting probability isn't marketing—it's what happens when you're traveling with MareTerra NGO scientists who actually know where to look. The boat itself is built for this: latest-generation engines that cut fuel consumption and underwater noise, because the whole point is to watch dolphins without disturbing them. You'll learn their names—Suzeo, Taz, Shark Junior—by their dorsal fins, the way the researchers do. The scientists on board will play you recordings of dolphin sounds they've captured, explain what the animals are doing, and answer the questions that pop into your head the moment you see them.

Once you've had your fill of watching, the snorkeling part begins in the crystalline waters of the Marine Protected Area of Capo Caccia - Isola Piana. If you've never snorkeled before, don't worry—the guides stay with you the whole time, and they've already asked for your shoe size before the trip so the masks and fins fit properly. You'll get a booklet to identify what you're seeing underwater, and the guides will point things out as you go. The whole experience is built around the idea that you're never alone on this boat, whether you're looking up at the sky or down at the water.

The tour runs in summer and depends on decent sea conditions, so there's always a small element of "will today be the day?" But that's also what makes it real. If dolphins don't show up, you keep looking and the cost doesn't change. If the sea gets rough enough that snorkeling isn't safe, you continue the dolphin search instead. Either way, you're out on the water with people who care about these animals enough to study them, not just point at them.

What’s included

Your day includes a marine biologist and certified interpretive nature guides on board, entry to the Marine Protected Area of Capo Caccia - Isola Piana, masks and fins for snorkeling, species identification booklets, and guidance in the water from a lifesaving-certified guide.

Is this one for you?Book this if you want to understand dolphins as animals rather than just see them, and if you're comfortable with the fact that wild sightings aren't guaranteed—the 80% probability and the scientists' expertise are what you're paying for, not a promise.
