Pleasanton Ridge Regional Park is located on a prominent, scenic wooded hillside above the town of Pleasanton. The most popular part of the park is located on the southern end of Pleasanton Ridge.
A much larger and more scenic unit to the north (separated from the southern unit by Pleasanton’s Augustin Bernal Park) features the ridge and a quiet, isolated valley beyond. This area requires more hiking to get to so it gets fewer visitors. The new Castleridge entrance has made it a little easier to get to this part of the park; another entrance near the north end is expected to open in about 5 years and promises to be the most scenic of all.
A large swath of Sunol Ridge, the next ridge to the west, is supposed to be added to the park eventually.
*** Turtle Pond (9.7 miles, 1770 ft)
This long hike in the park’s quiet northern section climbs to a prominent ridgetop with great views of the Tri-Valley area, then continues into the park’s isolated backcountry.
* The Ridgeline and Thermalito Trails (7.8 miles, 1680 ft)
This hike in the park’s popular southern section loops around the ridgetop.
