Poway · Mount Woodson · San Diego County
Potato Chip Rock Hike Guide
Last updated: June 2026
Potato Chip Rock is a thin granite slab cantilevered off the summit of Mount Woodson in Poway — and it’s probably the most-photographed spot in all of San Diego County. The photo looks insane from the right angle: a person standing on what looks like a cracker hanging over a 50-foot drop, except the rock has held up to thousands of visitors without so much as a crack.
The hike to get there is real — up to 7.5 miles round trip with 2,100+ feet of elevation gain on fully exposed terrain. This guide covers all three routes, the actual parking situation, the photo line reality, and the stuff every other guide skips.

Heads Up
This is a legitimately hard hike — fully exposed, zero water sources on the trail, and summer temps turn the granite into a frying pan. Heat exhaustion is the number one reason people call for rescue here. Go early, bring more water than you think you need, and skip it entirely if it’s over 85°F at trailhead time.
What the Hike Is Actually Like
The Lake Poway route starts flat around the lake, then turns into a sustained climb through open chaparral with almost no shade once you leave the tree line. The Hwy 67 route skips the lake scenery entirely and goes straight up a paved service road — shorter but less scenic and relentlessly steep.
Lower Mountain: The Approach
Open fire road and dirt switchbacks through scrub oak and sage. Decent views of Lake Poway behind you on the Lake Poway route. The trail is well-marked — no route-finding needed.
Mid-Mountain: Where It Gets Real
The grade increases and the vegetation drops away. Nothing between you and the sun from here to the summit. This is where unprepared hikers turn back, especially in summer.
The Summit: Radio Towers and 360° Views
A cluster of radio towers marks the summit — the rock is just beyond them. On clear days you get views to downtown San Diego, Mexico, the Salton Sea, and the Pacific. Usually a crowd waiting for the photo.
Potato Chip Rock: The Photo Moment
A 2–3 foot hop from the adjacent boulders and you’re on the ledge. The rock looks terrifyingly thin from the outside — standing on it feels surprisingly solid. One person at a time, no jumping.
3 Routes to Potato Chip Rock — Which One to Take
Most guides only mention Lake Poway. There are actually three trailheads, and picking the right one changes your total distance, parking cost, and crowd level.
| Route | RT Distance | Elev. Gain | Time | Parking | Best For |
|---|---|---|---|---|---|
| Lake Poway14644 Lake Poway Rd | 7.2–7.5 mi | 2,125 ft | 4–5 hrs | $10 Fri–Sun · Free Mon–Thu | Best scenery, most amenities |
| Highway 6716310 Hwy 67 — roadside | 4.2 mi | 1,204 ft | 2.5–3 hrs | Free street parking | Shortest, steepest, paved road |
| Fry-Koegel TrailOff Hwy 67 north side | ~6 mi | ~1,800 ft | 3–4 hrs | Free street parking | Quietest, unpaved, more wild |
Pro Tip
If you want the photo and nothing else, take the Hwy 67 route on a weekday morning. You’ll be done in under 3 hours and spend $0 on parking. The Lake Poway route is worth it if you want the full experience — better scenery, restrooms, a lake at the start — but budget a full morning.
Parking — What You Need to Know
Parking is the thing most people don’t research until they’re already sitting in their car at 9 AM on a Saturday. The three options have very different situations.
Lake Poway Recreation Area
Most Popular
$10/vehicle Friday–Sunday and holidays. Free Monday–Thursday. Lot has restrooms, water, and picnic tables. Fills up by 9–10 AM on weekend mornings — arrive by 7:30 AM if you want a spot.
Highway 67 Street Parking
Free
Free but limited — roadside pull-offs along Hwy 67 near Mt. Woodson Road. No amenities, no shade. This is the start of the shortest route. San Diego County has been planning a dedicated lot near the Ramona trailhead to address the ongoing parking chaos here — but as of 2026, it’s still roadside only.
Blue Sky Ecological Reserve
Free
Free parking, no fee. Used as the start for some longer loop routes. Hours: November–May sunrise–sunset, June–October 6:30 AM–sunset.
Money Saver
Hike on a weekday and parking at Lake Poway is completely free. If weekends are your only option, arrive before 8 AM — the lot fills fast and street parking on Lake Poway Road gets competitive quickly.
The Rock Itself — What Nobody Explains
Why Doesn’t It Break?
Most people call it sandstone. It’s not — Mount Woodson is tonalite, a hard granitic igneous rock with a compressive strength of roughly 19,000 psi. The slab looks impossibly thin from the classic photo angle, but it’s anchored into a much larger boulder mass beneath it, and the cantilevered portion is considerably thicker than it looks from the front.
The load of 2–3 standing people is distributed across the full base, not just the tip — structurally, it’s less of a chip and more of a diving board bolted into a mountain. It’s held up for decades and will likely hold for decades more.
The Jump — What to Expect
You can’t just walk onto the rock — there’s a 2–3 foot gap between the adjacent boulders and the ledge. Take off your backpack, hand it to someone, and hop across one at a time. It’s not a big jump but the drop below makes it feel bigger than it is.
If the rock is wet, skip it entirely — the tonalite surface becomes slick and you don’t want to find out the hard way. Also: do not jump on the rock after you land. Multiple people have been fined for reckless behavior here.
Random Trivia
In 2016, Poway’s mayor issued an April Fools’ Day press release announcing the rock had broken off. It went viral. The rock was, and remains, completely intact.
Best Time to Go
This isn’t a “any time is fine” hike. The combination of full sun exposure, granite that absorbs heat, and zero water sources makes timing matter more here than most trails in the county.
| Season | Temp Range | Crowds | Trail Conditions | Verdict |
|---|---|---|---|---|
| Spring (Mar–May) | 55–75°F | Moderate–High | Green hillsides, wildflowers | Best overall |
| Summer (Jun–Sep) | 80–105°F+ | Very High | Brown, dry, rattlesnake season | Early AM only |
| Fall (Oct–Nov) | 60–80°F | Low–Moderate | Clear views, comfortable | Local sweet spot |
| Winter (Dec–Feb) | 45–65°F | Low | Cold mornings, wet rock possible | Great, bring layers |
The Best Single Slot
A weekday morning in October or November between 7–9 AM. Cool temps, short photo line (if any), green starting to show after fall rains, and the light on the east-facing rock is perfect for photos until about 10 AM.
Dogs & Families
🐕 Bringing a Dog
- ✓Dogs allowed on all 3 routes on a 6-ft leash
- ✓Bring water for your dog — no water sources on trail
- !Stay 100 ft from lake shoreline at Lake Poway trailhead
- ✗Summer paw burn risk — granite hits 140°F+ in afternoon
- ✗Dogs cannot get on the rock for photos
👨👩👧 Bringing Kids
- ✓Kids 8+ with decent fitness can do the Hwy 67 route (4.2 mi)
- ✓Lake Poway route is longer but more gradual — better for young kids
- !Pack 1+ liter per child — they underestimate how much they’ll sweat
- ✗The 2–3 ft jump onto the rock is not safe for young children
- ✗Avoid July–August with kids — heat exhaustion risk is real
Practical Tips
| Tip | The Real Detail |
|---|---|
| Arrive before 8 AM on weekends | Photo line hits 30–60 min by mid-morning. Before 8 AM, you might walk straight up. After 10 AM on a Saturday, expect to wait. |
| Water: bring more than you think | 2.5 liters minimum per adult in spring/fall. 3+ liters in summer. There is no water on the trail and no shade to rest in. |
| Download offline maps | Cell coverage drops mid-trail. Download the AllTrails map or Google Maps offline before you leave the parking lot. |
| No sandals or flip flops | The trail is rocky and steep. Trail runners or hiking shoes with grip. Blisters are the number two reason people bail before the summit. |
| Sunscreen — seriously | The upper 60% of each route is fully exposed. If you forget sunscreen you will feel it the next day. |
| Don’t stand more than 2–3 on the rock | Not a formal rule but a weight distribution thing. The line moves faster when people are efficient about it anyway. |
| Emergency | Call 911 or San Diego County Sheriff: (858) 565-5200. The radio towers at the summit are a visual landmark for rescue response. |
Honest Take: Is It Worth It?
What’s Great
- ✓The photo genuinely looks incredible — it earns every repost it gets
- ✓Summit views are legitimately panoramic — you can see Mexico on a clear day
- ✓Multiple route options mean you can calibrate difficulty

- ✗The Hwy 67 route is a paved road, not scenic hiking
- ✗Parking at Lake Poway fills early on weekends
- ✗The rock itself is smaller in person than it looks in photos
Frequently Asked Questions
Can you drive to Potato Chip Rock?▾
No — there is no road access to the rock. The closest you can drive is the Highway 67 roadside parking area, from which it’s still a 4.2-mile round-trip hike. A lot of people assume it’s a roadside pullout you can just walk up to. It’s not.
Why doesn’t Potato Chip Rock break?▾
Because it’s not sandstone — it’s tonalite, a hard granitic rock. The slab looks terrifyingly thin from the photo angle, but it’s anchored into a much larger boulder mass beneath it and is considerably thicker than it appears from the front. Granite handles compressive loads of roughly 19,000 psi, which is wildly more than a few people standing on it.
Is there water on the Potato Chip Rock trail?▾
No water on the trail itself. Water and restrooms are available at the Lake Poway trailhead before you start. Once you’re on the trail, nothing. Bring at least 2–3 liters per person in summer and don’t count on finding any mid-hike.
Is there cell service on the trail?▾
Spotty. Generally fine at the trailhead and near the summit (there are radio towers up there), but the mid-trail section can lose signal. Download offline maps before you leave the parking lot — don’t rely on live navigation.
How long is the Potato Chip Rock hike?▾
Depends on the route. Highway 67: 4.2 miles round trip, 2.5–3 hours. Lake Poway: 7.2–7.5 miles, 4–5 hours. Fry-Koegel: about 6 miles, 3–4 hours. Add 30–60 minutes on weekend mornings for the photo line at the rock.
Do you have to jump to get on the rock?▾
Yes — there’s a 2–3 foot hop between the adjacent boulders and the ledge. Take off your pack, hand it to someone, and go one at a time. It’s manageable for most adults in reasonable fitness, but skip it entirely if the rock is wet. The drop below looks worse standing at the gap than it does from the photo.
Is Potato Chip Rock dog friendly?▾
Yes, dogs allowed on all routes on a 6-foot leash. At Lake Poway, they must stay 100 feet from the lake shoreline. The main hazard is heat — granite surface temps hit 140°F+ in summer afternoons. If you’re bringing a dog from May through September, go before 8 AM and bring extra water for them.
Is it safe for kids?▾
Doable for kids 8+ with decent fitness on the Hwy 67 route (4.2 miles). Start before 9 AM, bring at least 1 liter of water per child, and be upfront that there’s a wait at the rock on weekends. The 2–3 foot jump onto the slab is not appropriate for young kids — skip that part and take photos from the viewing area instead.
What is the best time to visit?▾
October through April, weekday mornings before 9 AM. Fall is the local sweet spot — cooler temps, shorter lines, clear views. Spring has better scenery with green hillsides. Summer is manageable only before 8 AM and only if temps are under 85°F at trailhead time. Avoid summer afternoons entirely.
Is there a new Ramona parking lot?▾
San Diego County supervisors voted to explore purchasing an 84-acre parcel near the Ramona trailhead to build a dedicated parking lot — addressing the long-standing safety issue of hikers parking along Highway 67. As of June 2026, the dedicated lot is not yet open, so roadside parking on Hwy 67 is still the only option for that route.
Nearby Worth Stopping For
| Place | Distance | Why Stop |
|---|---|---|
| Lake Poway | At the trailhead | Swimming, fishing, paddleboats — good for a post-hike cool down in summer |
| Iron Mountain (Poway) | ~15 min drive | Similar difficulty, better wildflowers in spring, less crowded |
| Old Town Poway | ~10 min drive | Post-hike food — Brigantine seafood and several solid taco spots |
| Julian | ~45 min east | Apple pie, cider, and mountain town charm — worthwhile day-trip pairing |
