Great and memorable experience
Really enjoyed the trip, we saw a huge pod of dolphins just after 15mins right. Our guide, Luis, is very knowledgeable and passionate about the national park. Lots of history to the area, highly recommended

Fantastic
Marta and Luis were a perfect team....Marta was able to tell us a lot about the dolphins....I also think it's great that all the boats exchange information when a group spots dolphins....we saw huge populations..
Thanks for the great experience
Operator response
Vielen Dank für Ihren tollen Kommentar!
Wir freuen uns sehr, dass Sie mit Marta und Luis eine so positive Erfahrung gemacht haben und dass Martas Erklärungen den Ausflug noch besonderer gemacht haben.
Der Informationsaustausch zwischen den verschiedenen Anbietern auf dem Meer ist tatsächlich sehr wichtig, um die Delfine leichter zu finden und vor allem, um eine verantwortungsvolle und respektvolle Beobachtung in ihrem natürlichen Lebensraum zu gewährleisten.
Wie schön, dass Sie die Gelegenheit hatten, so große Delfingruppen zu beobachten! Wir hoffen, Sie bald wieder in Sesimbra zu einem weiteren unvergesslichen Erlebnis mit den Delfinen begrüßen zu dürfen.
Bis bald!

tour
It was a bit of searching, also for our driver because the location is indicated somewhere else and that was unfortunately with another family as well. outside the price (125 for 1 adult and 3 children) I have nothing to comment on. the reception was very friendly by all the ladies, the necessities were explained and put on (safety first). the boat was small and pleasant. a lot of speed and smaller group. first a piece of the ocean. unfortunately no dolphins there. then back to land (were lost portugal for a while, which was no longer to see so far we were). and when we almost came to land suddenly a group of dolphins. got an explanation about all the dorfines and the other species that lived in this part. then a piece to land where we got a small piece of cake (was very tasty) and the adults a small half cup of wine. then back to port. the people know a lot, that is noticeable.
Operator response
Hartelijk dank dat u de tijd heeft genomen om uw ervaring met ons te delen en voor uw mooie beoordeling!
We zijn erg blij om te horen dat u genoten heeft van de ontvangst door ons team, de kleine groep, de boot en vooral van de uitleg van onze mariene bioloog. Wij vinden het belangrijk dat onze gasten niet alleen dolfijnen kunnen observeren, maar ook meer leren over hun gedrag en het bijzondere ecosysteem van Arrábida.
Het spijt ons dat het ontmoetingspunt moeilijk te vinden was. We zullen de locatiegegevens controleren om ervoor te zorgen dat toekomstige bezoekers dit probleem niet ondervinden.
Wat de prijs betreft, begrijpen we dat iedereen daar zijn eigen mening over heeft. Wij streven ernaar een hoogwaardige ervaring aan te bieden met kleine groepen, een snelle boot die ons meer flexibiliteit geeft bij het zoeken naar dolfijnen, begeleiding door een mariene bioloog en een toegewijd team dat veiligheid en kwaliteit vooropstelt.
Het doet ons veel plezier te lezen dat u, ondanks deze opmerking, van de excursie heeft genoten en de kans heeft gehad om dolfijnen in hun natuurlijke omgeving te zien.
We hopen u in de toekomst opnieuw in Sesimbra te mogen verwelkomen voor een nieuwe belevenis in het natuurpark Arrábida!

Nice Tour
Everything was organized well and the ride to the dolphins was very nice. On the ride back it was very nice that the crew provided a snack and a bit of wine. I would have given 5 stars except for the fact that I was waiting to be provided quite a lot about dolphins from a real “Marine Biologist” as per the title of the tour. We were only provided basic information and the crew were definitely not experts in marine biology. I was happy with all other details of the trip but my suggestion would be to change the title of the tour to accurately reflect the crew’s credentials and manage passenger expectations.
Operator response
