A nice lookout point over I-15. Just think of all the traffic you don't have to mess with while you're on a bike!

Lake Drive passes through the community of Del Dios and runs along Lake Hodges to the dam, offering scenic views of the lake and countryside. This road is also used as part of the Coast to Crest Trail. Hodges Dam was constructed in 1918; the reservoir is a key feature of this route. The trail is a mix of hard-packed doubletrack and some tighter singletrack near the dam, great for beginner and intermediate riders. It is popular for its ease and proximity to trailheads and rewarding views of the dam.

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.

This lovely reservoir has loads of nice trails around it. It is a great place for mountain biking with nice views. It is created by the damming of the San Dieguito River.
