    This preserve is a treasure trove of history, home to the remnants of three mining towns, including former coal and sand mines. The park features include an underground visitor center, guided tours of a former sand mine, and 60 miles (97 km) of trails to explore that crisscross the rolling foothill terrain. The trails offer stunning views of the surrounding landscape, which is a mix of grassland, California oak woodland, California mixed evergreen forest, and chaparral, making it a nature lover's paradise.
