Embarking in the longest annual migration of any mammal, the California gray whale travels in the neighborhood of 10,000 miles every year, spending about one third of its life swimming from the chilly nutrient-rich waters of Alaska to the warm lagoons of Baja California and back. During the trip, the incredible animals are often visible from the shores of Point Reyes.

The Point Reyes Headlands in the area of Chimney Rock and the Point Reyes Lighthouse offer one of the finest spots to watch the gray whale migration along the California coast, especially during the spring when the northbound whales travel closer to the shoreline thanks to the thrust of the Point Reyes Peninsula ten miles into the Pacific.
