Potato Chip Rock, Rock formation in San Diego County, United States

Potato Chip Rock is a thin, cantilevered slab of light tan rock that projects horizontally more than 14 feet from a broad, rounded granite mass on Mount Woodson, between 2,700 and 2,800 feet in elevation. Long vertical cracks and shallow depressions mark its coarse surface, and the projecting tip curves slightly, leaving open sky beneath it.

The rock sits on Mount Woodson, which was named in 1895 after a settler, replacing the Native American name Mountain of Moonlit Rocks. In 2017, Poway mayor Steve Vaus used the rock for an April Fools' Day prank, tweeting that part of it had snapped off and fallen into Lake Poway, with a picture as "proof".

The rock has become a destination for photographers and hikers seeking to stand on its narrow ridge. Visitors come here to capture images and share their experience with others.

Three routes reach the rock: a 6.6-mile round trip from the Lake Poway trailhead, a steep paved 3.75-mile round trip from an entrance at 16310 Highway 67, and the roughly four-mile Fry-Kogel trail. No water, toilets or rangers are available on any route, so carry your own supply.

This spot has become so popular that crowds form during peak times, with people lining up to take photos on the narrow ledge. The congestion is why many hikers prefer arriving early in the morning or on less busy days.
