Two routes, real distances, the line at the top, and the timing that separates a great morning from a miserable one.
Last updated
Potato Chip Rock is a thin granite slab near the summit of Mt. Woodson in Poway, and it's the most photographed hike in San Diego County. There are two ways up. From Lake Poway it's roughly 7.5 miles round trip with about 2,000 feet of gain, mostly on trail, and it takes most hikers four to five hours. From the Highway 67 trailhead in Ramona it's about 6 miles round trip on a paved service road — shorter and steeper-feeling, with easier parking but zero shade. Neither route is easy: this is a strenuous hike in full sun with almost no cover, and the exposed granite radiates heat. Go at sunrise, especially May through October, and carry at least two to three liters of water per person. The wait to take a photo on the chip can run 30 to 60 minutes on weekend mid-mornings and is often near zero at 7am on a weekday. Dogs on leash are allowed, but paw burns and heat exhaustion are the most common problems rangers deal with here.
| Distance | Gain | Surface | Best for | |
|---|---|---|---|---|
| Lake Poway route | ~7.5 mi round trip | ~2,000 ft | Dirt trail | The classic route, more scenic |
| Highway 67 route (Ramona) | ~6 mi round trip | ~1,500 ft | Paved service road | Shorter, free roadside parking |
| Lake Poway loop only | ~3 mi | Rolling | Dirt trail | Skipping the summit entirely |
The classic approach. You start at the lake, take the trail around the shoreline, then climb steadily through boulder fields to the summit ridge. More varied and more shaded in the first mile, but longer, and non-resident parking costs about $10 on peak weekends.
Local tip: The lot opens early and fills by mid-morning on weekends. If you're not parked by 7:30am in summer, expect to circle.
A paved maintenance road that climbs relentlessly to the same summit from the Ramona side. Shorter, easier to follow, and parking is free along the highway shoulder — but the pavement bakes and there is no shade at all.
Fit hikers and photographers favor Lake Poway for the scenery. People with limited time or a dog that needs a shorter day take Highway 67. Both end at the same rock and the same line.
Leave the trailhead at first light. You get cool air, soft light for photos, and often no wait at the chip. This single decision matters more than fitness.
The worst combination: full lots, full sun, and a 30 to 60 minute queue of people waiting their turn to step onto the slab.
December through April is the sweet spot — cooler temperatures, green hills, and long-view visibility to the ocean on clear days after rain.
Inland Poway routinely hits the 90s and above. Emergency responses on Mt. Woodson spike in summer heat. If you can't start by 6:30am, pick a different hike.
Two to three liters per person minimum in warm weather. There is no water on the trail and the last reliable restroom is at the trailhead.
Hat, sunglasses, sunscreen, and long sleeves if you burn. The granite reflects heat and light from below as well as above.
Trail runners or hiking shoes. The final scramble onto the chip involves stepping across a gap onto sloped granite — dry grip matters.
Allowed on leash, but hot rock burns paws and there's no shade to recover in. If you can't hold your palm on the trail for five seconds, it's too hot for a dog.
The slab overhangs a real drop. There is no railing, people take turns, and pushing for a photo in a crowd is how injuries happen here.
There are two routes to Potato Chip Rock and they are not comparable. Choosing wrong turns a moderate morning into a seven-mile ordeal in full sun.
Roughly 7-8 miles round trip with about 2,000 feet of gain. Shadier at the start, steeper in the middle, and the classic route. Non-resident parking fee applies on weekends.
Local tip: Lake Poway parking is free on weekdays for everyone; the weekend non-resident fee is cash-friendly and modest.
About 4-5 miles round trip on a paved service road. Shorter and easier to follow, but almost entirely exposed with no shade and limited roadside parking.
Local tip: This is the better summer route only if you start before 6:30am — the pavement radiates heat by 9am.
Both lots are full by 7-8am on Saturdays and Sundays year-round. The Highway 67 shoulder spots are the first to go.
Local tip: A Tuesday morning start has a fraction of the cars and almost no line at the rock.
Weekend waits for the photo on the chip regularly run 30-60 minutes. Weekday mornings are often walk-up.
Local tip: Budget the wait into your water and daylight planning, not just the hiking time.
Mt. Woodson is inland, which means it runs 10-20°F hotter than the coast on the same day. Nearly every rescue here is heat-related, not fall-related.
Three liters per person in warm months is the working standard. There is no water on the trail and no shade for the last two miles.
Local tip: Freeze one bottle overnight — it stays cold through the climb and thaws by the descent.
Sunrise start from May through October, and before 8am even in winter if you want parking. Afternoon starts on hot days are how people get in trouble.
Local tip: Check the inland forecast for Poway, not downtown San Diego — the difference is routinely 15°F.
Dogs are allowed on leash but the granite and pavement burn paws, and the final scramble is not dog-friendly.
Local tip: In summer, leave the dog home and take them to a bay-side trail instead.
The chip is a thin granite slab overhanging a drop. There's no railing, and the approach is a short scramble that feels bigger than it looks in photos.
Local tip: Hand your phone to the next person in line — everyone trades shots, and it's faster than a tripod.
Strenuous. From Lake Poway it's about 7.5 miles round trip with roughly 2,000 feet of climbing and very little shade, taking most hikers four to five hours. The Highway 67 route is shorter at about 6 miles but is a steady climb on hot pavement.
On a weekend mid-morning, expect 30 to 60 minutes to wait your turn for a photo. At sunrise on a weekday there is often no line at all.
Either the Lake Poway recreation area lot, where non-residents typically pay around $10 on peak weekends, or free roadside parking at the Highway 67 trailhead near Ramona. Both lots fill early on weekends.
The rock is a natural granite slab with no railing over a significant drop. It's generally safe if you go one at a time, step carefully on dry rock, and don't rush. Most incidents on the mountain are heat-related, not falls.
Sunrise, in the cooler months of roughly November through April. Summer starts should be before 6:30am; midday summer hikes on this trail are genuinely dangerous.
From Lake Poway it's roughly 7-8 miles round trip with about 2,000 feet of elevation gain, taking most hikers 3.5-5 hours including the photo wait. From the Highway 67 trailhead it's about 4-5 miles round trip on a paved, fully exposed service road.
The Highway 67 route is shorter and less steep, but it has no shade and very limited roadside parking. The Lake Poway route is longer and harder but has shade early, a real parking lot and water at the trailhead.
Parking is free on weekdays. On weekends and holidays, non-Poway residents pay a modest day-use fee at the entrance kiosk, and the lot typically fills between 7am and 8am.
Yes, but start at sunrise. Mt. Woodson runs 10-20°F hotter than the coast, the last two miles have no shade, and heat exhaustion is the most common reason for rescues on this trail. Carry three liters of water per person.
