A complete guide to San Diego's Potato Chip Rock hike. Three routes, 2,130 feet of elevation gain, water and timing tips, and what to expect on the iconic photo.
The Potato Chip Rock hike is San Diego's most iconic and most photographed hike — a 7.5-mile out-and-back trail to the summit of Mount Woodson (2,881 feet), where a thin, cantilevered blade of granite juts out from the rocks and creates the optical illusion of standing on a paper-thin slice of rock floating in space. The rock has become so popular that lines for a single photo regularly hit 30+ minutes on weekdays and over an hour on weekends.
If you're planning to tackle the Potato Chip Rock Trail, you'll want to know what you're getting into. The hike is continuously uphill, mostly unshaded, and physically demanding — but the views, the photo, and the local-legend status make it worth every step.
Three distinct routes lead to Potato Chip Rock. Pick based on your priorities: scenery, convenience, or solitude.
Distance: 7.5 miles round trip
Elevation Gain: ~2,130 feet
Difficulty: Hard
Time: 3.5–5 hours
Parking: $10 on weekends and holidays for non-Poway residents (Poway residents and active military with ID enter free)
Address: Lake Poway Park, 14644 Lake Poway Rd, Poway, CA 92064
Gates: Open at 6:00 AM
The Lake Poway route is the most popular for good reason. You start at one of San Diego's prettiest recreational lakes, follow the trail around the water for about a mile, then begin the steep ascent up Mt. Woodson Trail. Lake views become more dramatic as you gain elevation — and on clear days, you can see ocean glimpses on the horizon. Bathrooms, water refill stations, picnic tables, and shaded rest areas are available at the trailhead, making this the best choice for families and first-timers.
Distance: ~4 miles round trip
Elevation Gain: ~1,200 feet
Difficulty: Moderate (but steeper than Lake Poway)
Time: 2.5–3 hours
Parking: FREE on Highway 67 roadside
Trailhead: ~16310 Highway 67, near the Ramona Fire Station
The shortest route. You park alongside Highway 67 and follow the paved Mt. Woodson Road directly up. The pavement makes the trail more forgiving, but no facilities exist on this route — no bathrooms, no water, no shade. It's a faster path but a less scenic one.
Distance: 7.4 miles
Elevation Gain: ~1,624 feet
Difficulty: Hard
Time: 4–5 hours
Parking: Free residential street parking near Mt. Woodson Golf Club and Archie Moore Road
The quietest option. The Fry-Koegel Trail starts behind a residential area near the Mt. Woodson Golf Club. It offers substantially more shade through oak woodland sections and a quieter experience compared to the crowded Lake Poway route. Best for solitude seekers, hot summer days, and hikers who want oak canopy cover for most of the climb.
The trail is a continuous uphill climb that doesn't let up. From Lake Poway, you gain roughly 2,000 feet of elevation over 3.5 miles — equivalent to climbing 67 flights of stairs. Most of the route has minimal shade, with one lone oak tree around the halfway point that provides the only real shaded rest spot.
The scenery keeps things interesting:
The Mount Woodson summit feels crowded with antennas and cell towers. The Mount Woodson benchmark disk sits atop a boulder near a concrete silo, marking the official high point. From the summit, you have spectacular 360-degree views — but the real attraction is the rock itself.
Potato Chip Rock sits 0.2 miles past the summit, downhill on the west side. You'll need to:
The rock is structurally stable, but it vibrates when others jump on it. Wait times stretch:
Timing makes or breaks your experience.
Water is non-negotiable. Bring at least 1 liter per person per hour. 2-3 liters total per person is the safe minimum for the Lake Poway route. There's no shade, so dehydration is a real risk — especially in summer when temperatures can exceed 100°F.
Sun protection saves the day:
Snacks and trail food keep energy up, but pack out all trash — no trash cans exist on the trail. Bring a small ziplock for wrappers.
| Route | Parking | Cost |
|---|---|---|
| Lake Poway (weekends/holidays) | Paved lot with bathrooms | $10 (non-residents) |
| Lake Poway (weekdays) | Paved lot with bathrooms | Free |
| Lake Poway (Poway residents w/ ID) | Paved lot with bathrooms | Free |
| Lake Poway (active military w/ ID) | Paved lot with bathrooms | Free |
| Highway 67 | Roadside parking | Free |
| Fry-Koegel | Residential street parking | Free |
Dogs are welcome on leash. Restrooms, water fountains, and picnic areas are available at the Lake Poway trailhead.
Potato Chip Rock is one of San Diego's most rewarding hikes if you prepare well. Choose your route based on your priorities: scenery from Lake Poway, speed from Highway 67, or solitude from Fry-Koegel. Arrive early to beat the crowds and heat. Pack plenty of water. The challenging climb tests your endurance, but the views and that iconic photo make every step worthwhile.
