"Portola Redwoods State Park’s 3000 acres nestled at the base of Butano Ridge lie along the northeast side of Pescadero Creek on ridges bisected by Peters, Evans, Evergreen, and Slate creeks. Some of the largest redwoods in San Mateo County can be found in its shady canyons. The park adjoins San Mateo County ’s 8027-acre complex of Pescadero Creek, Memorial, and Sam McDonald county parks. On its northeast corner it abuts Long Ridge Open Space Preserve, which lies along the crest of the Santa Cruz Mountains amid thousands of acres of contiguous open space. The park offers miles of hiking trails through stately redwoods and mixed evergreen forests that tie in with these adjoining parks.
