Every year, tens of thousands of mobula rays flock to the Sea of Cortez in Mexico’s Baja California, creating an awe-inspiring spectacle featured in BBC’s Blue Planet and National Geographic documentaries. Imagine diving into a school of thousands, witnessing their leaps, and snorkeling above as they glide in unison. Out in the blue, we can expect the unexpected—alongside mobula rays, there are chances to encounter killer whales, humpback whales, megapods of dolphins, blue whales, fin whales, sperm whales, whale sharks, and more. This annual migration is truly unlike anything else on Earth.
