  • Close encounters with the friendly gray whale cows and calves in San Ignacio Lagoon, a UNESCO World Heritage Site.
  • Opportunities to see blue, fin, humpback, Bryde's, sperm, and killer whales in the Sea of Cortez.
  • Comfortable land-based accommodations in beautiful Baja California.

Baja California's San Ignacio Lagoon is the primary calving ground for eastern Pacific gray whales and part of Mexico's El Vizcaíno Biosphere Reserve—the largest wildlife refuge in Latin America. The large concentration of gray whales that reside here each winter are extremely 'friendly,' and regularly approach our small whale watching pangas (skiffs) in a moving display that occurs nowhere else. The whales are the focus of our trip, and we will have three full days to observe them. We expect to see large numbers of gray whales, including cow-calf pairs, courting whales, and others.

At the start of our trip, we also take two days to explore the Sea of Cortez, one of the most productive and diverse seas on the planet. From our base in the quaint town of Loreto we will make a private boat excursion to search for marine mammals and to enjoy the outstanding landscapes of the Gulf of California. Here we have the possibility to see blue whales, the largest animals ever to exist on Earth, fin whales, Bryde's whales, sperm whales, humpbacks, and herds of dolphins.

Wildlife Highlights

The highlight of our trip will be the three full days spent with gray whale mothers and their curious calves in San Ignacio Lagoon. The protected lagoon is also a wintering ground for migrating birds, and we may see White Ibis, Elegant Terns, Reddish Egrets, Brown Pelicans, Brandt's Cormorants, Brant Geese and others.

We also explore the wildlife of the productive and diverse Sea of Cortez, which is home to more than 650 tropical and temperate fish (90 of them endemic) and one-third of the world's whale and dolphin species. On land, an exceptional 695 vascular plant species are scattered among colorful and rugged desert landscapes. On our excursions we have the possibility to see humpback, blue, fin, Bryde's, and sperm whales, dolphins, sea lions, "flying" rays, and many bird species.
