Marin Headlands Nature Tour
Discover the California marine environment, from tide pool creatures to marine mammals to shore birds. Visit seals, sea lions and otters at the Marine Mammal Center. Nearby trails open up the Coastal Range (mountains) to a drier habitat of bobcats, fence lizards and hawks. Explore hands-on exhibits for kids of all ages at the Golden Gate National Recreation Area Visitor Center.
Located in an international "biosphere reserve," the Marin Headlands are the main component of the Golden Gate Biosphere Reserve, so designated by a wide range of plants and animals in a small area (less than 10 square miles, or approximately 2589 hectares).

Earthquake Geology
The area is well known to geologists throughout the world for its large ribbon chert rock exposures. Chert is a flint-like sedimentary rock which formed on the ocean floor, and is often found near earthquake fault exposures. These cracked and sinuous strata cover about one-half of the Marin Headlands, with easily visible fault intrusions.

Point Bonita Lighthouse on the Rugged Pacific
In addition to plentiful rock, plant and animal
features, the Park accesses the nearby marine
environment of the Pacific ocean, including peaceful Rodeo Lagoon,
Kirby Cove beach, where semi-precious orbicular jasper can often be found washed up by the sea, and rugged, picturesque Point Bonita Lighthouse.

Marine Mammal Rehabilitation Center
The Marine Mammal Rehabilitation Center (undergoing renovation) located nearby, offers a rare up-close visit with pelagic pinapeds (fin-footed mammals living in the open sea). Although injured, recuperating in a hospital, most seals, sea lions, otters, dolphins and whales, are guided and released to the sea after a short stay to heal.
