An Authentic Marine Adventure from the Start
The experience kicks off at Diving Center Megadive, a well-equipped meeting point, at 9:45 am. The early start ensures you’ll be out on the water when the sea is often calmest and wildlife most active. The check-in process is straightforward, and the staff is noted for being friendly and accommodating—a great foundation for a relaxed, enjoyable trip.
The Itinerary and What Makes Each Stop Special
After a brief safety briefing, your boat departs towards the Professor Luiz Saldanha Marine Park. This protected area, part of the Arrábida Natural Park, is crucial because it provides a more predictable environment for dolphin sightings, thanks to its conservation measures.
The first stop is Porto de Sesimbra, where you set out cruising along the coastline. Here, the emphasis is on scenic sightseeing, with the chance to get your first glimpses of the coast’s rugged cliffs and lush greenery. As one reviewer noted, the boat was “very comfortable,” which makes a difference when you’re spending a good chunk of time on the water—especially with young kids or if you’re prone to seasickness.
Stops at CV7Q+XV, Ribeiro do Cavalo Beach, and Baleeira Beach are all about enjoying spectacular views and taking photos. You might find these spots are also perfect for a quick swim or relaxing on the sands. The opportunity to jump in the water and cool off is a real plus, and the tour includes snorkeling masks, so you can get a closer look at the marine life just beneath the surface.
Dolphin Watching – The Main Event
The core of the tour is, of course, dolphin spotting. Traveling through the protected Marine Park, the guides—particularly the marine biologist—share insights about dolphin behavior, habitat, and conservation efforts. This background makes the experience more engaging than a typical boat ride; you’re actively learning while watching.
The success rate of about 98% means most trips result in dolphin sightings. According to one review, “we were able to see the dolphins and the beautiful landscapes,” which underscores how rewarding this outing can be. The dolphins are known for their antics, often jumping and playing in the waves, providing fantastic photo opportunities.
Beach Breaks and Refreshments
Between wildlife spotting, you’ll have chances to swim at beaches like Ribeira do Cavalo or Baleeira Beach. These spots are described as “paradisiacal” and perfect for a quick dip or relaxing under the sun. The tour also includes a traditional Sesimbra sweet, adding a local touch to your seaside break.
Practical Details and Logistics
The tour costs $57 per person, which includes life jackets, snorkeling masks, insurance, and the traditional sweet. Not included are food and drinks—so if you want a meal, you’ll need to bring your own or plan to buy something ashore afterward. The boat is described as very comfortable, and the group size is manageable, ensuring a more intimate experience.
One of the more appealing aspects is the flexibility to cancel up to 24 hours in advance and the option to reserve now and pay later, making it easy to adapt your plans.
Who Will Love This Tour?
This trip is ideal for families with children, as evidenced by one review praising the experience for a 15-month-old. It’s also perfect for nature lovers and photography enthusiasts eager to capture elusive wildlife and stunning landscapes. If you’re looking for a leisure activity that combines wildlife, scenery, and a bit of adventure, this tour hits the mark.
Who Might Not Find It Perfect?
Keep in mind that since dolphins are wild animals, sightings are never guaranteed 100%. If wildlife is your only priority and you’re on a tight schedule, it’s worth considering this uncertainty. Also, the tour is not catered for those who want a full-day experience—it’s a concise 3 hours, focusing mainly on dolphin spotting and coastal scenery.
Final Thoughts on Value
At $57, the tour offers a well-rounded experience—combining wildlife, scenery, and beach access—guided by experts. Compared to other marine excursions, the focus on education with the marine biologist adds to the value, making it more than just a boat ride. Plus, the chance to see wild dolphins in their natural habitat is a rare treat that few other experiences can match, especially with a high sighting success rate.
