The Stonewall Peak Trail hike is the most popular hike in Cuyamaca Rancho State Park for good reason. It’s not too tough, offers great 360 views from Cuyamaca Rancho State Park to Anza-Borrego Desert State Park, and has a unique bald rock face summit. Give the hike a try, you won’t be disappointed. Stonewall Peak, at 5730ft high, is also right next to the 2nd highest peak in San Diego County, Cuyamaca Peak, and both can be hiked in a day. Break your hikes up with a picnic in Paso Picacho Campground.
