Perhaps the most compelling of the wildlife sights that San Ignacio Lagoon offers are the pods of eastern North Pacific gray whales that visit each year. They spend the winter in these waters, attracted by their relative warmth. And they present whale-watching opportunities that are probably unmatched by any other location in the world.
This eastern population of gray whales spends the summer in the nutrient-rich waters between Russia and Alaska. In the winter the whales migrate en masse southwards along the Pacific coasts of the U.S. and Mexico, where they breed and give birth. The protected waters of the San Ignacio Gulf make an ideal nursery, away from predators.
