The Clarkia Trailhead lies to the south of the park, off Cañada Road, about a half mile south of the Edgewood/Cañada Road intersection. Limited roadside parking is available. Clarkia Trail is the only trail that traverses the southern end of the park, starting in grassland and then transitioning into warmer, more shrubby chaparral with blooming annual plants and shrubs. There is a photogenic rock outcropping approximately 0.3 of a mile up from Cañada Road. Clarkia Trail ends in a junction with the Sunset Trail near the Sunset Trailhead.
