Trail Overview
The trail to Potato Chip Rock varies in length and difficulty based on the chosen route.

The Lake Poway route begins at the lake’s parking lot and follows a dirt trail with a steady incline. Hikers will pass through chaparral-covered hillsides, gaining elevation gradually before encountering steeper switchbacks as they approach the summit.

Along the way, there are panoramic views of Poway, the surrounding mountains, and glimpses of the Pacific Ocean on clear days. The last section of the hike is rugged, leading to the summit of Mount Woodson, where Potato Chip Rock sits just below the peak (GPS: 33.0092287, -116.974183).

The Highway 67 route is a paved, direct ascent up Mt. Woodson Road. While this option is shorter, the continuous incline can be challenging. The route lacks shade, making early morning or cooler months the best hiking times. Despite its difficulty, this path is a quicker option for those looking to reach Potato Chip Rock with less mileage.

Once at Potato Chip Rock, hikers often queue to take photos standing on the rock’s edge, with dramatic drop-offs creating a striking visual effect. Despite its precarious appearance, the rock is stable, though caution is advised when climbing onto it.
