Brazil Altantica Cruse Line offers immersive natural history voyages along Brazil’s Atlantic coast and offshore islands, blending scientific inquiry with experiential travel. Our expeditions pair expert naturalists and marine biologists with small-ship comfort, delivering close-up encounters with coastal ecosystems, seabird colonies, and marine megafauna while supporting research and conservation—creating meaningful journeys for curious travelers and citizen scientists alike.

We are guided by curiosity, stewardship, and scientific integrity: every itinerary is designed to deepen understanding of Atlantic biodiversity while minimizing impact and contributing to ongoing research. We prioritize respectful engagement with local communities and Indigenous knowledge, transparent collaboration with conservation partners, and exceptional safety and education for guests, so each voyage leaves both passengers and habitats better informed and better protected.
