Witness Humpback Whales (Seasonal)

Between July and November, Abrolhos becomes a crucial breeding and calving ground for humpback whales. During these months, boat tours often incorporate dedicated whale-watching excursions, providing an awe-inspiring opportunity to observe these magnificent creatures in their natural habitat.

Tip: If visiting during whale season, choose a tour operator specifically advertising whale watching to maximize your chances of a sighting. Remember to maintain respectful distances.

Visit the Caravelas Visitor Center

Before or after your boat trip to the archipelago, make a stop at the Abrolhos National Marine Park Visitor Center located in Caravelas. This center provides valuable information through panels, videos, and exhibits, including a life-size replica of a humpback whale, enhancing your understanding of the park's biodiversity.

Birdwatching Opportunities

Tip: Bring a good telephoto lens for your camera if you are passionate about bird photography, as some species may be observed from a distance.

Experience a Sunset Over the Lagoon

While the focus is marine, the unique location within the lagoon and near the mainland offers stunning views. Consider enjoying the sunset from your boat or from the mainland in Caravelas. The changing light over the water creates a beautiful, serene end to your day.
