The Monterey Bay National Marine Sanctuary is the largest marine park in the United States. It is a gem of the subsea world that emerged from disaster following decades of overfishing and pollution along the California coast. From microscopic organisms to marine mammals, ocean life thrives here, supported by one of the world's largest Kelp forests that acts like an underwater rain forest. And onshore, one of the world's top marine research facilities, the Monterey Bay Aquarium, re-creates the habitats of this incredible Ocean Park.
