The Santa Fe Valley Trail is a 3.6-mile trail in the San Dieguito River Park. Parking is available at the San Dieguito River Park staging area. The trail starts near a private golf club, with a narrow single track running alongside a chain link fence. It then passes under a bridge and includes several wooden footbridges over creeks. As you continue, you get nice views of the riverbed and might see wildflowers in the spring and summer. The trail features gentle switchbacks out of the riverbed that help make the climb manageable and leads to a great view at the top. Leashed dogs are allowed, but for the safety of pets and people, be aware that rattlesnakes do live in the area. This is a popular spot for hikers, so please be respectful when riding this trail.
