Tips from the Community
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.

The stretch of trail through Coyote Hills Regional Park lives up to its name, with rolling hills that are fun, but not to the point of being technical, to ride.

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.

The Hayward Shoreline Interpretive Center, established in 1986, is a fantastic educational center for school groups and the public to learn about the significance and history of the wetlands surrounding San Francisco Bay. Several exhibits, programs, and activities are designed to cultivate appreciation, respect, and stewardship for the bay and its diverse wildlife. There is parking and restrooms available here.
