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.

McNee Ranch State Park is a beautifl state park that is part of Montara State Beach and on the western side of Montara Mountain. There are several miles of trails that wind through the park, many with amazing coastal views.

Devils slide itself is nice and just to the south is the beautiful Gray Whales Cove beach. There is plenty of parking at both places. Two notes for cyclist: 1. cycling along Hwy 1, coming from Pacifica, requires climbing on a relatively narrow but highly frequented road. It is not a long climb until the turnoff to Devils slide, but it might be stressful for cyclists who are not used to riding in heavy traffic. Hwy 1 south of Devils slide has enough space for everyone. 2. If you cycle on Hwy1, then check the wind forecast beforehand. Dominant wind direction is NW, which means cycling southbound maximizes tailwind and minimizes breathing in all the air pollution from stinky cars.
