PROCETUS is a science-led ecotourism and marine research initiative based in Baja California, Mexico. We combine responsible wildlife expeditions with real scientific research on whales and other marine wildlife. Our work focuses on long-term monitoring of Baja’s marine megafauna—especially cetaceans—while also collaborating on research projects to better understand and protect whales around the world. Every expedition supports conservation through data collection, photo-ID, drone observations, and community involvement. At PROCETUS, travelers don’t just witness the ocean—they become part of the effort to study and protect it.
