This 9,000-acre wooded preserve provides a glimpse of what this countryside was like before the developers took over. Trails wind through ancient oak forests and past vernal pools and rolling grassland. A visitor and operations center has interpretive displays and maps; some of the reserve's hiking trails begin here. There are designated trails for leashed dogs, horses, and mountain bikers. Take I–15 south to Clinton Keith Road exit and head west 5 mi.
