The hike

A moderately strenuous hike will take you to the top of Flag Hill, which is composed of layers of fossil-rich sandstone formed some 13 million years ago. You'll enjoy great views and good opportunities to watch birds and other wildlife.

The trail

Begin this hike by crossing Alameda Creek on the footbridge near park headquarters. Turn left (downstream). After a short distance, Flag Hill Trial will take off uphill, to the right. The trail zigzags up the face of the hill (make sure your hikers understand why it's important not to shortcut switchbacks). After about a mile of rather steep uphill hiking, you'll reach the top where you'll probably want to take a good snack or lunch break.

While on top, watch for red-tailed hawks (the red upper surface of the tail is visible when the hawk turns), turkey vultures (which hold their wings in a slight "V" and teeter in flight), and maybe even a golden eagle or falcon.

Continue your hike by going down the back side of Flag Hill, turning right when you reach High Valley Road. Return to the cars by way of Hayfield Road.

The history

Sunol Regional Park area was inhabited by the Ohlone Indians for about 4000 years. In 1797, when the mission was built at Mission San Jose, most of the Indians moved to the mission. The Indian camp was located on the same site as the Green Barn and park office are now located.

On the Fourth of July in 1903, a group of children climbed a hill located north of the present park headquarters, and planted a flag. The hill thereafter was known as Flag Hill.
