Fifth trip and still absolutely magical! 🐬
On this 5th experience, Catarina and André were still as fantastic as ever! The outing led us to a great number of bottle-nose dolphins and we were lucky to see Risso's dolphins, one of the rarest sightings world-wide. A highly recommended trip that I will continue to repeat :)

I love this adventure!
I’ve gone out with this boat five times over two (or three?) years. It is always SO fun! The sea creatures in Sesimbra just give and give more! I hate to spoil any expectations, but I will say that I’ve never been disappointed, nor seen anyone aboard less than thrilled. If you haven’t been….just go.

Fabulous experience and staff
We really had a fabulous time. Not too long, not too short. I must say that we were lucky to see dozens and dozens of dolphins too! The staff was amazing, particulary one girl that did the effort to speak with us in French all along the trip with kindness. We will definitely see you again soon :)

A not to be missed experience in Sesimbra !
We loved this trip! Marco and Victor were great guides and took really good care of us. The beaches, bays and caves were beautiful and we really enjoyed swimming from the boat and snorkelling. Victor gave us so much information about the history of Sesimbra and the area. We also enjoyed an aperitif on board. Thank you!

Arrábida Secret Beaches and Caves with Snorkeling Stop

An absolutely incredible outing! 🌊☀️
We had an exceptional time discovering the secret beaches and magnificent caves of Arrábida. The landscapes are simply breathtaking, with turquoise water and places accessible only by boat. 🤩The stop for snorkeling was also great: magnificent water, superb seabed, and a real feeling of escape. 🐠The guides were really great, very friendly, professional, and attentive. They contributed greatly to making this experience even more pleasant and memorable. 😊It is clearly one of the best moments of our stay in Portugal. 🇵🇹❤️An activity that I recommend 100% and that I would do again without hesitation! ⛵️🌊

Observation of Dolphins in Setúbal

Incredible
It was spectacular. We were able to observe the dolphins well and the team that accompanied us was excellent. With very interesting explanations and indications. On a small boat, almost full only with our family, it was an incredible experience. Although the amount to pay is high, it is worth it, which is why we highly recommend it. Thank you (Rafael and the other boy whose name I don't remember).

Fantastic day out
The whole experience was amazing, very well organised. Good facilities at the base and really helpful staff. We did a private boat tour with Leonor, she was an excellent guide to the region. Extremely knowledgeable and enthusiastic about the wildlife and the beautiful Arrabida coastline. She managed to get us to all the most beautiful spots before the crowds descended. The whole family had a great time.
