All Midpen Preserves are open to the public free of charge, 365 days a year from dawn until one-half hour after sunset.

Coal Creek is an ideal place for a quick afternoon hike with one's dog. Several trails can be combined to create a pleasant two- or three-mile loop. Views of the San Francisco Bay Area can be seen from the open grassland ridges below the Caltrans vista point parking area.

The preserve's five miles of trails provide important trail connections between Skyline Boulevard and Alpine Road for hikers, bicyclists, and equestrians. Mountain bicyclists take advantage of this connection to complete loops through Russian Ridge back to Portola Valley.


Coal Creek Open Space Preserve can be reached from the Caltrans vista point pull-out area on Skyline Boulevard (opposite Russian Ridge Preserve gate RR01), approximately 1.2 miles north of Page Mill Road and 6 miles south of Highway 84. Coal Creek is also accessible to hikers, bicyclists, and equestrians from Alpine Road.
