Augustin Bernal Community Park is a 237- acre open space community park in the City of Pleasanton offering outdoor recreation and educational opportunities for visitors of all ages and abilities. Located on the top and east face of Pleasanton Ridge, the park provides hiking, biking and equestrian trails with spectacular views, plus opportunities to explore a vestigial landscape that is disappearing in California. Sharing large sections of its west, south and north boundaries with East Bay Regional Park District’s Pleasanton Ridge Regional Park, the park protects a valuable portion of the ridge and also secures a link in a “necklace of green,” nearly encircling San Francisco Bay. *2

Once part of Golden Eagle Ranch, Augustin Bernal Community Park was granted to the City of Pleasanton in 1971 by Walter S. Johnson, a noted philanthropist and industrialist who was known for his generous support of the Palace of Fine Arts restoration in San Francisco. When he donated the land to the City, he did so with the understanding that it be maintained and operated for public park and recreational purposes in perpetuity. The park is named for the Spanish settler, Augustin Bernal, who held the original land grant for the property. *2

Begin this trail hike from the pedestrian access located at the north side of the park by Longview Dr cul-de-sac. Park at the bottom of the hill underneath the eucalyptus groves and walk up the steep road to the driveway at 9104 Longview Dr.

The trail provides the occasional glimpse of the suburban valley below along with the steady hum of traffic along I-680.

The trail leads up through to the gorgeous oak groves and open green meadows. To experience Augustin Bernal Community Park is to learn about the varied landscapes that can occur side-by-side on a typical site in California. On the steeper north-facing portions of the park, there are mixed oak woodlands with Coyote Brush and Poison Oak. On the south-facing hillsides, there are large areas of dense chaparral vegetation consisting of Coffeeberry, Monkey Flower, Toyon and Chamise. *2

Cut across the open grassland towards Ridgeline Trail into Pleasanton Ridge Park. Along the ridgeline, the woodland thins out to a savannah featuring annual grasses and scattered oak groves. Because much of the park escaped the damages of grazing animals, many native species still remain such as the large patches of California Fescue, a native bunch grass. As for seasonal color, visitors will enjoy the many native wildflowers such as Baby Blue Eyes, Chinese Houses, and Shooting Star.*2 Grassland is the dominant plant community of Pleasanton Ridge Regional Park. The woodland communities are made up of mixed stands of coast live oak, Californa bay laurel, blue oak, black oak, valley oak and Oregon oak. Like the grasslands, the woodland undergrowth contains numerous grasses and wildflowers.*1

  1. Hi guys, great turn by turn hiking blog. I’ve been to the ridge twice for biking but only gone as far as the vista point. I’ll follow this blog for my next “exploration” trip. thank you.


  2. Thank you so much for this in-depth guide to the hike. How long (time and distance) would you say it is from where you park to the northern part of Ridgeline Trail?


  3. kay, you’ll need to click on the individual park trail maps, calculate the mileage between trail junctions and divide that by your average hiking pace.
