Since that time, the Tijuana River National Estuarine Research Reserve protects, preserves and manages the natural resources of the Tijuana River Estuary. The reserve includes beaches, dunes, marshlands, coastal sage scrub and upland habitats that are surrounded by the major urban areas of Tijuana, Imperial Beach and San Diego. Visitors can walk miles of trails and learn about how the estuary functions and local residents at the Visitor's Center.
