Point Reyes National Seashore encompasses approximately 71,000 acres of grassland, forest and shoreline along the Pacific coast north of San Francisco. The diversity of habitat is home to nearly 40 species of land mammals. While driving or hiking through the seashore you are likely to see some of these residents, such as bobcat and the Tule Elk. The shoreline, that interface between the aquatic and terrestrial environments, provides prime haul-out and breeding sites for several species of seals and sea lions. The adjacent marine waters (which include two National Marine Sanctuaries) support at least 25 species of whales and porpoises that can sometimes be seen from the mainland.
