The 1,051-acre Tijuana Slough National Wildlife Refuge, in Imperial Beach, is southern California’s only coastal estuary that is not interrupted by roads and rail lines. The slough is an essential breeding, feeding, and nesting ground, and a key stopover on the Pacific Flyway for over 370 species of migratory and native birds, including the endangered California least tern, least Bell's vireo, California brown pelican, and light-footed clapper rail. Changes in water flow through the slough can be extreme, from a mere trickle during periods of drought to flooding during storms and high tides. The visitor center and a few miles of trail leading from it are accessible. This wildlife refuge is part of the 2,500-acre Tijuana River National Estuarine Research Reserve.

Visitor center: Surrounded by a native plant garden, the visitor center has permanent exhibits that highlight estuary flora and fauna, estuarine ecology, and natural processes. Free interpretive programs and guided hikes for children and adults are offered. Call for schedules.
