Martin – United Kingdom

Fantastic trip, seen many dolphins just 15mins from setting off. Then finished with a cruise down the coast back to the marina. Great trip, friendly staff and worth every penny. Would 100% recommend.

This boat trip was excellent. Instructions and communication from the company were very helpful. We set off on time and were so very well looked after. We were so lucky to see the dolphins after an exhilarating and comfortable ride out to sea. The boat stopped when the dolphins were near and we were able to view them swimming alongside the boat and all around the area. Could not recommend this tour or company enough. We were a group of six and were offered water and wind jackets during the journey. We were out for just over two hours and the experience was exceptional and one we will always remember. Wonderful to see these beautiful animals in their environment.

Full description

The route of encounters. Where we connect with these incredible sea creatures: the dolphins. The grace with which they welcome those who visit them, with their jumps and acrobatics, fills our hearts with lightness and admiration.

The tour begins at the Cascais Marina and we normally head out to our observation points of these magnificent creatures off the Cascais coast, maximising the client's experience.

The tour is run in complete safety, with profound respect for the animals and in optimal weather, sea and light conditions so that the sighting of dolphins (and, on many occasions, cetaceans) result in an unforgettable encounter in their natural habitat.

We accompany the dolphins with the necessary distance, allowing everyone to record the moment, always with safety and respect for the animals as the two main premises of our service.

Perfectly organised tour !! Very professional , caring and commited guides doing everything to make this an unforgettable experience. Informative about the dolphins and the ocean. One of the guides sat next to our younger daughter while the boat was speeding and making turns to make sure she was ok and comfortable. Very good atmosphere due to the calmness and friendliness of the guides. We highly recommend to book a dolphin tour or any other tour here !! You will not regret !!
