Rancho Santa Fe Golf Course (PRIVATE) is a 4.5 mile lightly trafficked loop trail located near Rancho Santa Fe, CA. The trail is good for all skill levels and primarily used for trail running.
It's really flat, but was out walking the dog and found this. Kept seeing signs that it's private, it runs along the main roads, so I don't see how that can be. Saw nobody else out except a couple golfers on the course.
