The John J. Collier Interpretive Center, open on weekends, holds a museum with live animals and displays on regional natural history. Nature education programs and summer camps run from the center. The park's three vegetation zones, coastal sage scrub, oak woodland and riparian, can be compared along the trails.

Over 4 miles (6 km) of trails cross the three canyons, ranging from flat to moderate incline; a typical trail runs about 0.3 mile (0.5 km). Lower trails sit in partial shade, while the ridge top is fully exposed to the sun. The John J. Collier Interpretive Center opens on weekends.

A year-round stream runs through the property and sustains a rare woodland habitat with oak trees and coastal vegetation. These natural conditions have become scarce in the surrounding area.
