Learn about earthquake geology on this relatively flat hike. One of the world’s longest and most active, the San Andreas Fault splits this preserve; pick-up a brochure map at the trailhead to be guided through the 9 station self-led interpretive hike. The trail starts on the left side of the parking lot. Go through the fence and up the hill to station number 1; follow your map from there. This easy hike with minimal elevation change is well suited for children and those needing a less physically challenging outing.
