San Pedro Valley's rich history and its wildlife are well documented in the Visitors Center of the San Mateo County park. Well-maintained hiking trails lead up from the parking areas towards McNee Ranch State Park and Montara Mountain to the southeast, and along the hills below Sweeney Ridge to the north. The south and middle forks of San Pedro creek flow year-round through the park. Steelhead trout still spawn in San Pedro creek. Brooks Falls, an easy trail away from the visitors center, is especially noteworthy after winter rains.
Picnic tables are available in several spots near the visitors center.
The Plaskon Nature trail is a very short stroll between the two main parking lots. The Brooks Falls Overlook trail and the Old Trout Farm trail combine to make an easy loop in the southern end of the park. The Valley View trail follows the slope of a ridge in the north end of the park, winding back down to the Weiler Ranch road which will take you back to the visitors center. A longer walk starts from the visitors center southeast on Weiler Ranch road, then branches right onto the Hazelnut Trail. Not necessarily a bad thing.
