Went to here end of 2015. I enjoyed the hike. There are still many people on the potato chip rock even in week day. You should avoid weekend in order to avoid in the long line to take a picture there. Not many details, but I plan to go here again.
Trailhead: 14644 Lake Poway Road, Poway, CA 92064
Third visit on May 5, 2018:
1:20 for going up, and 1:13 to get down. The weather forecast was not hot day, and started early to avoid excessive sun. I met one gentlemen on way up, and it was very nice to talk him on the trail.
Fourth visit on May 12, 2018
People gathered together on this cloudy day. I was little worried because there was a little rain on the way to the trailhead. We started about 10 minutes late because waiting people to join. The most part of junctions, take a left except the last two junction. If you are not sure where to go, follow the sign that said Mount Woodson Trail. Trailhead elevation is about 950 ft, and the summit where potato chip rock is about 2,846 feet. Total elevation gain is about 2000 ft, less or more depending on your route.
