"If you have only a few hours to spend in this wonderful preserve, consider this loop as an introduction to some of the attractions that make visiting here worthwhile: beautiful scenery, diverse plant life, and a reminder of the area’s not-so-distant past as a thriving coal-mining district. This trip can easily be combined with a visit to historic Rose Hill Cemetery. (Numbers in boldface in the route description refer to sites on the EBRPD map and accompanying text.)
From the south end of the parking area, pass a gate and continue uphill on the Nortonville Trail, a paved road, for about 200 feet to a level area and a junction, left, with the Stewartville Trail, a dirt road. Turn left and begin walking uphill on a moderate grade that soon levels, heading southeast through open country. This part of the preserve has native trees common to inland areas of the East Bay—gray pine, blue oak, California buckeye—along with nonnatives brought in by early settlers, including eucalyptus, black locust, tree of heaven, and peppertree, a transplant from Peru with aromatic leaves and pink, peppercorn-like fruit."
