The Bay Trail is paved and takes you right up along the water's edge. On the inland side of the causeway, you can see the tidal marshlands that comprise Heron Bay.

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.

On the eastern shore of San Francisco Bay, Eden Landing Ecological Preserve spans about 5,040 acres in size. It was formerly an industrial salt pond from Oliver Salt Company, and the remains can still be found today. Ongoing restoration efforts have rehabilitated over 1,000 acres of marshland as bird habitat. In April of 2016, new trails and a kayak launch were opened to the public.

At this spot along the trail, you can see some Archimede's screw pumps at work. These interesting mechanisms are an old school system for irrigation.

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.

Entry point to the Hayward Shoreline trail. You'll have to travel through some industrial areas to reach this point, and the trail is gravel. Not overly populated, but there is some road noise from the San Mateo bridge.

Long gravel stretch was no issue for my hybrid commuter on a dry day. Nice and quiet, it's a lightly populated trail.
