This long, dark-sanded beach has a well-packed coastal trail which follows the water's edge between the pier and Mori Point. It connects to a great network of trails along the ocean on the south side of town.

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.

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.

Gray Whale Cove State Beach is a beautiful, secluded beach located nine miles north of Highway 92 along Highway 1. This 800-foot stretch of white sand is nestled in a small valley known as "Devil's Slide" and is shielded from the highway by cliffs. The beach is named for the gray whales often spotted here during their spring migration. Facilities include free day parking, chemical toilets, but no water, so keep this in mind as you ride.
