If you are a sea lover don't let the less warm temperature stop your curiosity! For three hours, we search for dolphins. Thanks to the presence of the researcher of MareTerra NGO, our chance of spotting dolphins is 80%. During the navigation, a briefing will be provided to let you know more about the biology and behaviour of dolphins, along with their conservation status. We are certified with the High Quality Whale Watching certification. Once we sighted a group of dolphins, we respect their well-being approaching them in accordance with the "good code of conduct" of our certification to minimise the risk of any disturbance to dolphins. Thanks to the photo-identification technique, we can recognise dolphins by their dorsal fins and we are able to tell you their names, how old they are and their health status. In addition, you will listen to the dolphin sounds thanks to the recordings that the scientists of MareTerra NGO collected to study the bioacoustic of the dolphins. During the navigation, you will admire one of the most beautiful coasts of Sardinia, within the boundaries of the Marine Protected Area Capo Caccia - Isola Piana.

Finally, a dolphin tour that pays attention to not disturb the species unnecessarily. I was impressed by the information provided and the enthusiasm of the tour guides. We were able to participate in data collection and observe a dolphin in its natural habitat. Simply magnificent. You are doing a great job, helping with education and thus contributing to an improvement in the treatment of the world. Thank you very much!

This tour was a great way to spend 3 sunny hours in late May. Francesco, Guillermo and the rest of the crew gave us lots of information and tried their best to find Dolphins for us to see and for them to study. We only got to see 2 Dolphins but we got good sightings of them, always remember wildlife can be unpredictable so there's a lot of luck involved. The boats are well maintained and clean, there is no water supplied so make sure to bring some. The fee for the tour goes to help fund research so by taking this tour you are helping to give the Dolphins abetter chace to live longer and better lives.

My husband and I took part in the tour with Fabio who we thank for his professionalism and friendliness. It was a wonderful experience during which we got to observe different groups of dolphins up close and learn so much about the sightings, habits and behaviors of these extraordinary animals. Highly recommended tour!!!

Unfortunately, we were not lucky enough to see dolphins on 25.04.2026, and yet we would book the tour the same way again. We had a great trip with lots of interesting information about dolphins and their way of life. The information was backed up by pictures and recordings, which was very interesting. At the meeting point we stood on the wrong side of the road 🙈 , but this was no problem either. Fabio called me and we cleared up the misunderstanding. Everything totally easy🥰 thank you, Fabio 😊 On the way back we were allowed to admire Alghero from the sea and also feel the horsepower of the boat 😂 We can highly recommend this tour. Thanks to Fabio and Francesco. 👍😊

We were hoping to see the dolphins but first encountered a fin whale. Only a small one (14m) but longer than our boat, just wandering around feeding. Took no notice of us and apparently quite rare in this area. Then we found the dolphins, several in each group, lots of young with their mother. Altogether an amazing few hours, well worth it and hopefully a small contribution to the research.

This tour is led by researchers affiliated to the University of Sassari. We observed 3 bottlenose dolphins and the whole trip was really great. Thanks!!

An unforgettable experience! Thanks to Fabio and Francesco I had the chance to see dolphins and whales along the coast of Alghero. Their great professionalism and passion are perceived at all times, always in full respect of the marine environment. I recommend this experience to anyone who wants to experience something authentic and exciting, led by people who really love their territory.
