The Thermalito Trail at the south end of the park


The very popular Pleasanton Ridge Regional Park is located on a prominent, scenic wooded hillside above the town of Pleasanton. The long, narrow park has two separate parts: the southern part is much more popular since it has the park's only official entrance, while the northern part is much larger and more scenic, and can be reached using a little-known easement. New entrances to the northern part are planned, the first of which will be at the Alviso Adobe.


** Pleasanton Ridge and Turtle Pond (12.6 miles, 2280 ft)

* The Ridgeline and Thermalito Trails (7.8 miles, 1680 ft)
This hike in the park's popular southern section loops around the ridgetop.
