The California coast is home to a diverse array of marine mammal and bird species, with many easy access points for viewing tours. The coastline sees annual migrations of blue, gray and humpback whales, and nearly year-round sightings of fin and minke whales. A variety of dolphin species, including Risso's dolphin and killer whales, may also be seen. The gray whale migration lasts from January through May, peaking in March. Humpbacks follow a similar schedule, with numbers of fin and blue whales peaking in August.
