Overview
The Abrolhos Archipelago, situated off the southern coast of Bahia, Brazil, encompasses a cluster of five volcanic islands surrounded by some of the most biodiverse coral reefs in the South Atlantic. These protected waters serve as a critical breeding ground for humpback whales between July and November, while year-round residents include sea turtles, reef sharks, and an extraordinary variety of endemic corals.
Expedition vessels anchor offshore and deploy zodiacs for wet landings on designated islands within the Abrolhos Marine National Park. The whale season from July through October offers the most compelling wildlife encounters, though tropical heat and humidity are constant factors. Travelers should prepare for basic landing conditions with no developed infrastructure on the islan

The warm, shallow waters surrounding the archipelago attract hundreds of humpback whales each austral winter, offering exceptional zodiac-based observation of breaching, tail-slapping, and nursing behaviors.
Tip: Bring polarized sunglasses to reduce surface glare and spot whales more easily.
The Abrolhos reefs harbor mushroom-shaped coral formations found nowhere else on Earth, creating an underwater landscape teeming with tropical fish, sea fans, and brain corals.
Tip: Reef-safe sunscreen is mandatory within the marine park boundaries.
The islands' rocky shores and sparse vegetation provide nesting habitat for magnificent frigatebirds, brown boobies, and red-billed tropicbirds, viewable at remarkably close range during guided walks.
Tip: Keep a respectful distance from nesting colonies and follow the expedition naturalist's guidance at all times.
