Cuyamaca Peak, the second highest point in San Diego County, looms tall on the western edge of Cuyamaca Rancho State Park. There are many trails and fire roads that can be used to craft different routes up the summit, but the most direct and popular course is to climb the Lookout Fire Road, starting at Paso Picacho Campground. This road, being entirely paved asphalt, is also the only hike in the park that dogs are allowed on.
