Welcome to the Monterey Bay National Marine Sanctuary! One of our nation's most spectacular marine protected areas, the Monterey Bay National Marine Sanctuary offers some of the best wildlife viewing in the world! This "Serengeti of the Sea" stretches along the central coast from San Francisco to Cambria and includes pristine beaches, jewel-like tide pools, lush kelp forests, steep canyons and an offshore seamount teeming with life—from tiny shrimp to giant blue whales. The National Marine Sanctuary System promotes environmental protection, stewardship and ocean research. We invite you to explore and help protect this national undersea treasure.
