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.

Milagra Ridge forms what biologists refer to as an island ecosystem surrounded by urban development. Volunteers work to preserve the area and ensure that the local endangered species, such as California red-legged frogs and San Bruno and Mission blue butterflies continue to thrive. Visitors are required to stay on the trail, and pets must be leashed. There is a gate at the entrance that prevents cars from entering.
