Point Reyes National Seashore is 70,000 acre (283 km²) park preserve located on the Point Reyes Peninsula in Marin County, California, USA. As a national seashore, it is maintained by the US National Park Service as a nationally important nature preserve within which existing agricultural uses are allowed to continue. Clem Miller, a US Congressman from Marin County wrote and introduced the bill for the establishment of Point Reyes National Seashore in 1962 to protect the peninsula from residential development which was proposed at the time for the slopes above Drake's Bay. Miller's vision included the continuation of the historic ranching and oyster farming along with the preservation of the grasslands and open scenic vistas. The mix of commercial and recreational uses was the reason the area was designated a National Seashore rather than a National Park.
Point Reyes was one of the locations where the 1980 horror film The Fog was filmed.
The small town of Point Reyes Station, although not actually located on the peninsula, nevertheless provides most services to it, though some services are also available at Inverness on the west shore of Tomales Bay. The even smaller town of Olema, about three miles south of Point Reyes Station, serves as the gateway to the Seashore and its visitor center, located on Bear Valley Road.
The peninsula includes wild coastal beaches and headlands, estuaries, and uplands, with a coastline that bears a striking resemblance to Cape Point, Cape of Good Hope, South Africa. Although parts of the Seashore are commercially farmed, and parts are under the jurisdiction of other conservation authorities, the National Park Service provides signage and seeks to manage visitor impact on the entire peninsula and virtually all of Tomales Bay. The Seashore also administers the parts of the Golden Gate National Recreation area, such as the Olema Valley, that are adjacent to the Seashore.
The Point Reyes National Seashore attracts 2.5 million visitors annually.
Across the parking lot at the Visitor's Center is the Earthquake Trail which is is a 0.6 mile loop that runs directly over the San Andreas Fault, deep underground. so that it is possible to stand straddling the fault line. The trail provides descriptions of the fault and the surrounding geology, and there is a fence that was pulled 18 feet apart during the 1906 San Francisco Earthquake.
At the western end of the Point Reyes Peninsula is the historic Point Reyes Lighthouse, reached by descending 308 steps. Unlike many lighthouses, that were built high so the light could be seen by ships far out to sea, the Point Reyes lighthouse was built low to get the light below the fog that is so prominent in the area. Nearby is the short Chimney Rock hike, which is noted for its spring wildflower displays.
As befitting a national seashore, Point Reyes offers several beach walks. Limantour Spit winds up on a narrow sandy beach, from which Drakes Beach can be glimpsed across Drakes Bay. North Beach and South Beach are often windswept and wave-pounded. Ocean vistas from higher ground can be seen from the Tomales Point Trail and, to the south, from the Palomarin trailhead at the park's southern entrance outside the town of Bolinas.
For backpackers, Point Reyes has four hike-in campgrounds available by reservation.
In his book The Natural History of the Point Reyes Peninsula, Jules Evens identifies several plant communities. One of the most prominent is the Douglas fir (Pseudotsuga menziesii) forest, which covers most of the Bear Valley trail and the Inverness Ridge through which it passes.
The Bishop pine (Pinus muricata) forest is found on slopes in the northern half of the park. Many of these trees growing in thick swaths came from seeds released after the 1995 Mt. Vision fire.
The other communities identified by Evens are the coastal strand, dominated by European beach grass (Ammophila arenaria), ice plant (Carprobrotus edulis, also called sea fig or Hottentot fig), sea rocket (Cakile maritima) and other species that thrive on the immediate coast; northern coastal prairie, found on a narrow strip just inland from the coastal strand that includes some native grasses; coastal rangeland, the area still grazed by the cattle from the peninsula's remaining working ranches; northern coastal scrub, dominated by coyote bush (Baccharis pilularis); marshlands--salt, brackish, and freshwater--and the intertidal and subtidal plant communities.
