A Closer Look at the Arrábida Dolphin and Whale Watching Tour

This boat trip takes place within the protected waters of Arrábida Natural Park, a haven for marine biodiversity just a short drive from Lisbon. The tour is designed to be educational and respectful, blending wildlife observation with environmental awareness—a perfect fit for eco-conscious travelers who want more than just sightseeing.

The Itinerary Breakdown

The adventure begins at the ESPADARTE tourist boarding pier, a convenient meeting point clearly marked near the Clube Naval de Sesimbra. After boarding the boat—typically a small vessel that allows for close-up views—your journey into the ocean begins. The marine biologist guide, often Catarina or her team, will share fascinating facts about the area’s ecosystem, focusing on dolphins, whales, and other creatures like sunfish, sharks, and migratory birds.

Dolphin sightings tend to happen pretty quickly, according to reviews, which is a big plus. Guests have described seeing pods of dolphins, including babies swimming with their mothers, and even spotting a whale or two during the trip. Multiple reviewers highlighted how knowledgeable and passionate Catarina is—her explanations make the experience richer and more engaging.

The boat ride itself is described as both fun and exciting, with many reviewers noting how close they got to the animals. Some mention that the smaller size of the boat makes viewing much easier and more intimate compared to larger, less personal tours. The crew’s dedication to minimizing stress on the animals is a recurring theme, resonating well with wildlife lovers.

Wildlife and Bird Watching

While the star attractions are undoubtedly the dolphins and whales, the tour’s scope extends beyond. Expect to see various bird species, especially during quieter moments or when navigating along the coast. Some reviews mention sharks, sunfish, tuna, and swordfish—a reminder of the diversity in this marine protected area.

The Swim Stop at Ribeiro do Cavalo Beach

A highlight for many is the swimming stop at Ribeiro do Cavalo. Once hailed as one of Europe’s most beautiful beaches, this spot is a hidden gem. The crystal-clear waters and rugged coastline make it an ideal place to relax, swim, or snap photos. However, some reviewers felt that the beach stop could be more focused on wildlife rather than just leisure, but most agree that it adds a nice break to the trip.
