Journey to the Lagoons! Why do Pacific gray whales migrate over 5,000miles south to the Lagoons of Baja each year? Gray whale calves are born with only a small layer of insulating blubber. Imagine enduring a frigid Alaskan winter with a light jacket. Cold right? The warm, protected lagoons of Baja act as a nursery for growing calves. During their 12-13 week stay in the lagoon, the calf will nurse on their mother's high-fat milk to triple their birth weight. Not only will they be strong enough to make the journey north, they will have a nice blubber layer to keep them warm in the Arctic waters.
