The American Canyon Wetlands Open Space is located in and around the City of American Canyon, and managed jointly by the City of American Canyon and the Napa County Regional Park and Open Space District.  Following the Napa-Sonoma Marsh shore line, the trails provide a variety of ways to explore the marshland and Napa River.  The wetlands can be accessed by the Napa River Trail, which when complete, will follow the Napa River between Wetlands Edge Drive in American Canyon to Trancas Crossing Park in the City of Napa, and by the San Francisco Bay Trail, which when completed will circle the San Francisco Bay.  The wetlands are a great place for bird watching and enjoying the sunrise or sunset. There are two entrances to the trails, one at the end of Green Island Road (where there is also a kayak and canoe launch ramp and other short unimproved levee-top trails) and the other on Wetlands Edge Road and Eucalyptus Drive where there is paved parking and porta-potties.
