You can still see evidence of what used to be the Cold War-era radar targeting system of Nike anti-aircraft missiles; the missiles themselves were based on nearby Milagra Ridge.

This isn't the sort of road you'd take a vehicle on, nowadays - but it's great for nontechnical mountain biking, and this high point gives you nice views over the surrounding hills.

This is a great spot to stop and take in the 360-degree views of the sprawling landscapes of the coastal meadows and the Pacific Ocean. Slightly to the north, you can see Bolinas Pt. in the distance.
