Sailing, wildlife, and thrilling encounters with whales and dolphins in the Alcatrazes Archipelago
Discover the wild and preserved side of the northern coast with an experience that blends adventure, contemplation, and a direct connection with nature
The northern coast of São Paulo holds secrets far beyond its famous beaches. In the depths of this stretch of the Brazilian coastline pulses a vibrant marine life, within one of the richest and most preserved ecosystems in the Southeast region. Among the gems of this coastline is São Sebastião, a historic town and gateway to experiences that unite adventure, nature, and contemplation.
A true ecological sanctuary, São Sebastião boasts marine life in every wave, every rocky shore, and every bird soaring through the blue sky. The city offers visitors unique and thrilling opportunities to spot whales, dolphins, seabirds, sea turtles, and even hammerhead sharks. And it’s in the Alcatrazes Archipelago, a paradisiacal refuge about 35 km off the coast, that you’ll experience unforgettable moments observing this incredibly rich marine life.
ALCATRAZES ARCHIPELAGO
Alcatrazes stands out as one of Brazil’s best-kept treasures, home to more than 1,300 animal species. It is also the largest frigatebird nesting area in the South Atlantic and serves as a feeding, breeding, and resting site for over 10,000 seabirds. Its crystal-clear waters are a true natural aquarium, with the highest concentration of fish in Southeast Brazil.
As it is an environmental conservation area, visits to the archipelago are only allowed with authorized companies and guides. In addition to appreciating the scenic beauty and biodiversity, you can go snorkeling for direct contact with nature.
TIP: The best time for cetacean watching is between July and October, when humpback whales are most likely to be seen, although dolphins and Bryde’s whales may be spotted year-round.
CETACEAN WATCHING
Humpback whales are the most frequently seen in the waters of São Sebastião. From May to August, with the peak of the season typically occurring in June and July, they take advantage of Brazil’s tropical waters to mate and give birth.
To observe the dance of humpbacks, Bryde’s whales, and the leaps of several dolphin species, the best option is a boat tour to Alcatrazes. A trip that combines stunning scenery, marine life, crystal-clear waters, and the exciting chance to see animals up close in their natural habitat.TIP: The best time for cetacean watching is between July and October, when humpback whales are most likely to be seen, although dolphins and Bryde’s whales may be spotted year-round.
