Wander the Wetlands of Watsonville
The City of Watsonville’s nature trails provide easy public access to this 800 acre freshwater wetland. More than six miles of paved trails and 29 trail entrances in Watsonville neighborhoods offer new opportunities to enjoy the natural beauty of our special wetlands for recreation and relaxation.
City wetland trails are free to use and open every day in every season. Joggers, hikers, cyclists and birders are welcome to access any of the trails. Several trails are wheelchair accessible; please see trail maps for appropriate entrances.
Dogs are permitted on leash only. To wildlife in the wetlands, off-leash dogs are often perceived as predators, causing unintentional wildlife disturbance and habitat damage. Dog owners are required to pick up their pet’s waste. Please help protect our wildlife and water quality by utilizing a pet waste bag and disposing of it in the trash.
