The Napa River and Bay Trail is a Class I (paved) pedestrian and bicycle path which will eventually connect from the southern boundary of the City of American Canyon to the northern boundary of the City of Napa. Over two-thirds of the population of Napa County lives in the area served by this trail.
Except for the section north of Imola Avenue in the City of Napa, the route is also part of the ambitious 500 mile-long region-wide San Francisco Bay Trail, now a little more than half completed.
There is ongoing work on this trail network and new additions and improvements will be made over time. These trails popular with locals and visitors alike, and are a great option for a walk along the water to enjoy the bay & river and enjoy birds and other wildlife.
There are several trailheads to access this regional trail, the most heavily frequented being Wetlands Edge Park, a partnership between the Napa Open Space District and the City of American Canyon. In partnership with the city, the Napa Open Space District has constructed about 5 miles of the trail at Wetlands Edge, with just over more 4 miles remaining to be completed.

History of the Wetlands
The waters, wetlands and uplands you see along the Napa River Bay Trail are part of an interconnected watershed system that drains into the San Francisco Bay. Before the 1850’s, San Francisco Bay had edges with extensive, miles-wide tidal marshes. By the 1950’s, nearly 85% of these marshlands had been diked or filled. The low-lying flood plains found in American Canyon include mudflats, tidal and seasonal wetlands, former salt ponds, riparian corridors, and lands reclaimed for agriculture and development. These “baylands” provide habitat for waterfowl, shorebirds, fish and wildlife species.
