Potato Chip Rock: My Local's Guide to San Diego's Most Famous Hike
Paul Stritmatter·Jun 3, 2026·5 min.
The Potato Chip Rock hike is the most photographed trail in San Diego. My local's guide to all three routes up Mount Woodson — with the truth about the climb, the photo wait, and exactly when to go to beat the crowds.
The Potato Chip Rock hike is the most photographed trail in San Diego, full stop. The draw is a thin, cantilevered blade of granite near the summit of Mount Woodson (2,881 feet) that looks, in a photo, exactly like you're standing on a paper-thin slice of rock floating in midair. It's become such a phenomenon that the line for a single photo regularly runs 30+ minutes on weekdays and over an hour on weekends.
I'll be straight with you about what you're signing up for: this hike is continuously uphill, mostly unshaded, and genuinely demanding. But the views, the photo, and the local-legend status make it worth every step. Here's everything I'd tell a friend before they go.
If you only read one section, make it this:
There are three ways up, and the right one depends on whether you want scenery, speed, or solitude.
This is the route most people take, and for good reason. You start at one of San Diego's prettiest lakes, follow the shoreline for about a mile, then begin the steep grind up the Mt. Woodson Trail. The lake views get more dramatic as you climb, and on clear days you'll catch glimpses of the ocean on the horizon. It's also the most equipped trailhead — bathrooms, water refill stations, picnic tables, and shaded rest areas — which makes it the best pick for families and first-timers.
The fast way up. You park along Highway 67 and follow the paved Mt. Woodson Road straight up. The pavement makes for more forgiving footing, but there are no facilities at all — no bathrooms, no water, no shade. It's quicker, but less scenic.
The route for solitude seekers. It starts behind a residential area near the Mt. Woodson Golf Club and offers substantially more shade through oak woodland — which makes it my pick for hot summer days when the other routes bake.
This is a continuous uphill climb that just doesn't let up. From Lake Poway, you gain roughly 2,000 feet over 3.5 miles — the equivalent of about 67 flights of stairs. Shade is minimal, with one lone oak around the halfway point that's the only real shaded rest spot on the way up.
The scenery keeps it interesting, at least. Boulders and rock formations line the trail and make good natural break points, the Lake Poway views get better the higher you go, and on a clear day you'll spot the ocean in the distance. The summit itself is a little cluttered with cell towers and antennas — the official high point is marked by the Mount Woodson benchmark disk on a boulder near a concrete silo — but it's easy enough to walk around for the full 360-degree view.
The rock everyone comes for sits 0.2 miles past the summit, downhill on the west side. Getting your shot means scrambling down a boulder, jumping across a roughly 3-foot gap to step onto the rock, and posing while the line of waiting hikers watches. It's structurally stable, though it does vibrate a little when others hop on.
Plan for the wait, because it's real: 30–40 minutes on weekdays, and over an hour on busy weekends (people have reported 100+ in line). Sunset gives you the best light but also the biggest crowds.
Timing makes or breaks this hike. Arrive before 9 AM on a weekday for any shot at solitude (Lake Poway gates open at 6 AM). Avoid summer weekends unless you've made peace with the wait. And if you're hiking for sunset, bring a headlamp — the trail gets dark fast on the way down.
Water is non-negotiable. Bring at least a liter per person per hour, with 2–3 liters total per person as the safe minimum on the Lake Poway route. There's no shade and no water on the trail, so dehydration is a genuine risk — especially in summer, when it can top 100°F up there.
Sun protection saves the day. Sunscreen (reapply at the summit before heading down), a hat or sun hoodie, a long-sleeve sun shirt on high-UV days, and shoes with good grip for the rocky sections. Pack snacks too, and bring a small ziplock for your wrappers — there are no trash cans on the trail.
This hike is a great fit if you're reasonably fit and can handle a sustained uphill climb, if you're after that iconic photo, or if you want a serious San Diego hike with a real payoff. It works for families with older kids (think 12+) and for sunset hunters who don't mind descending with a headlamp.
I'd think twice, though, if you've got knee, ankle, or back issues — the steep descent is brutal on joints. Same goes if you're uncomfortable with heights (the photo means standing on an exposed rock with a drop on either side), if you can't carry 2–3 liters of water, or if you're hoping for an easy, shaded stroll. Potato Chip Rock is none of those things.
If you prepare well, absolutely. Choose your route by what you want most — scenery from Lake Poway, speed from Highway 67, or quiet from Fry-Koegel — get there early to beat the crowds and heat, and carry plenty of water. The climb will test your endurance, but the views and that floating-rock photo make every step worth it.

How difficult is the Potato Chip Rock hike?
The Lake Poway route is rated hard — a continuous uphill climb with about 2,130 feet of gain over 3.5 miles to the summit, roughly 67 flights of stairs. Minimal shade and rocky terrain make it demanding, especially in heat, so come fit and prepared.
How long does it take?
The Lake Poway route runs 3.5–5 hours round trip depending on your pace, plus the photo wait — 30–40 minutes on weekdays, over an hour on busy weekends.
Which route is shortest?
Highway 67, at about 4 miles round trip with ~1,200 feet of gain. It follows paved Mt. Woodson Road with free roadside parking, but there are no facilities and no shade.
What should I bring?
At least 2–3 liters of water per person, sunscreen, a hat, sun-protective clothing, shoes with good traction, snacks, and a bag to pack out trash. There are no trash cans on the trail.
When's the best time to go?
Before 9 AM on a weekday. Lake Poway gates open at 6 AM, and an early start means the shortest photo lines and coolest temps. Sunset has the best light but the biggest crowds — and you'll need a headlamp coming down.
San Diego's highest peak packs 950 feet of climbing into 1.5 miles. Here's what to bring, when to go, and what to expect.
