Alghero: Dolphin Watching Tour with Marine Biologists – A Close Encounter with Sardinia’s Marine Life
Thinking about a trip to Sardinia and wanting to see some of its most captivating wildlife? This dolphin watching experience in Alghero might just be what you’re after. Led by marine biologists from MareTerra ERC, this tour offers a chance to observe bottlenose dolphins in their natural habitat while learning about their behaviors and biology. Plus, if you’re visiting between June and September, you get an added bonus with guided snorkeling in a protected marine area.
What we love about this experience is how it balances education and adventure. You’re not just sitting on a boat hoping to spot dolphins—you’re actively learning about these intelligent creatures from experts, and your participation supports ongoing conservation projects. The tour also boasts an impressive 80% sighting success rate, so the chances of actually seeing dolphins are pretty good.
On the flip side, a notable consideration is the unpredictability of wildlife sightings. Since these are wild animals, you might not always encounter dolphins, no matter how well-informed the guides are. Also, if you’re not keen on boat rides or can’t stand the possibility of no sightings, this might not be the ideal activity for you.
This tour is best suited for travelers who appreciate a mix of nature, science, and a responsible approach to wildlife tourism. It’s a solid pick if you’re passionate about marine life or simply want a meaningful, educational adventure on Sardinia’s stunning coast.

The Experience in Detail

What Happens During the Tour
Once underway, the guides will share their latest findings about the local bottlenose dolphin population. They’ll explain their behaviors, how they recognize individual dolphins through dorsal fin photos, and how their movements relate to the environment. This offers a fascinating glimpse into marine biology that’s rarely available on standard boat tours.
If dolphins are spotted, the boat will follow strict protocols under the High-Quality Whale Watching (HQWW®) certification to minimize disturbance. You’ll see the dolphins in their natural setting, often in small groups, and might even hear their communication sounds through a hydrophone. The guides are skilled at approaching dolphins responsibly, so you’ll get a genuine, non-intrusive encounter.
Snorkeling and Marine Life Observation
From June to September, the tour includes a stop in the Marine Protected Area of Capo Caccia and Isola Piana. Here, guided snorkeling adds an extra layer of fun and discovery. Masks and fins are provided, so you won’t need to bring your own unless you prefer. Expect to see more marine life beyond dolphins—crustaceans, fish, and possibly even sea turtles—making this part of the trip especially engaging for those eager to explore underwater.
Duration and Flexibility
The tour lasts between 3 to 4 hours, with the shorter option running from April, May, and October. The longer tour with snorkeling is ideal for those wanting a full immersion in Sardinia’s marine environment. The flexibility of departure times means you can pick a slot that fits your schedule, and the entire experience concludes back at the starting point.
More Great Tours NearbyAdditional Considerations
While the experience is well-organized, keep in mind that no sighting is guaranteed—these are wild animals, after all. The guides’ high level of knowledge improves your odds, but nature remains unpredictable. The tour is not suitable for children under five or pregnant women, likely because of the boat ride’s nature and safety considerations.

What Makes This Tour Stand Out?

First, the educational element is genuinely engaging. Talking with marine biologists offers a lot more depth than typical wildlife cruises, making this suitable for anyone curious about marine ecosystems. Second, the responsible approach—adhering to strict guidelines to protect dolphins—means you can enjoy the experience while helping conservation efforts.
The scenic coastal backdrop of Sardinia is stunning, providing a beautiful setting to relax and take photos. The boat ride itself is likely to be smooth and comfortable, especially with the modern, purpose-built vessels. The optional snorkeling enriches the trip, turning it into a full sensory adventure.
Price vs. Value
At around $57 per person, this tour offers good value, especially considering the expertise of the guides, the scientific data collection, and the inclusions like snorkeling gear. Compared to less interactive or purely sightseeing options, this one provides a meaningful connection to marine life, making the cost worthwhile for many travelers.
Real Traveler Feedback
One reviewer summarized it simply as “Sehr gut,” or very good, highlighting the overall positive experience. Many comments praise the friendly, knowledgeable guides and the high success rate of dolphin sightings. Others appreciate the chance to listen to dolphin sounds with bioacoustics research tools—an unusual and memorable feature.
Who Is It Best For?
This tour suits travelers who enjoy learning about wildlife and want a responsible, eco-conscious experience. It’s great for those comfortable on boats and eager to see dolphins in the wild, but not ideal for very young children or those seeking a purely leisure-focused trip. If snorkeling or marine biology excites you, you’ll find it especially rewarding.
