Don Edwards San Francisco Bay National Wildlife Refuge is an excellent place to visit whether you are looking to take a leisurely walk, engage in some birding, or finding a new challenging trail. Whether you go on a short walk or hike a longer trail, there are over 30 miles of trails for you to explore.
Trail Closure Alert:
Mallard Slough Trail is closed due to construction as well as sections of Alviso Slough Trail at Don Edwards San Francisco Bay National Wildlife Refuge in Alviso California.
South San Francisco Bay Shoreline Project (Phase I) between the Alviso Slough/Guadalupe River and Coyote Creek is underway. The project, once completed, will protect north San José, including the community of Alviso and the Regional Wastewater Facility, from a 100-year coastal storm and rising seas.
