During this unique experience we aim not only to observe the dolphins in their natural habitat but also to locate and collect floating plastic. It will thus be developing its environmental education as well as that of the smaller ones. Embark on Sesimbra and gain the opportunity to see other species (such as the common dolphin) as well as explore the entire coastline of the Arrábida Natural Park up to the Sado River. Its estuary is a point of prime importance for the conservation of dolphins, since they live there all year round, making this place a unique place considering that there are only three in all of Europe.

Fantastic trip, very knowledgeable and friendly. Spoke excellent English making the trip fun and educational. Just myself and my dad on the trip which was lovely. Special memories made.
Thank you so much for your wonderful review! It's great to know that our guide's knowledge and friendly demeanor made the experience both fun and educational for you. We look forward to serving you again in the future!
The crew was very friendly and knowledgeable. Since we only found a dolphin cardume, they offered us the trip along the coastal caves as an extra, i.e. 2 excursions for the price of 1
Great times! We went to see the dolphins (we saw about twenty) it was great. In addition Anthia made us visit the coast (cave, beach, fort ..) explaining. Also, they are very protective of nature and asks us to warn them if we see plastic, waste etc so they can pick them up. And we drop off at ribeira do Cavallo where we spent the whole day and picked us up at the end of the day. Very good experience and very friendly staff. I recommend.
Amazing experience, very safe for humans but also for animals, they take care of not disturbing them and keeping water free from plastic. For Kids this is a must. We enjoyed the morning watching how dolphins jump and swim. It was so nice
Hello Gaby, Thank you for your kind words. Looking forward the see you soon.
We saw and experienced a lot on this tour. Not only dolphins, but also the coast and information about Sesimbra. Very friendly Guids! Worth every penny 👍
