This guide takes you inside the Tijuana Estuary National Park Point of Interest. It is a standout point of interest nestled in Imperial Beach, California, just north of the U.S.–Mexico border. This living sanctuary of coastal wetlands offers a breathtaking blend of environmental research, wildlife habitat, and public exploration. It is an estuarine oasis unlike any other along Southern California’s coastline.
What Makes the Tijuana Estuary Park Unique
The Tijuana River Estuary is one of the largest intact coastal wetland ecosystems remaining in Southern California. It serves as an essential stopover along the Pacific Flyway for over 370 migratory and native bird species. These include endangered ones like the Light-footed Ridgway’s Rail and California Least Tern. It experiences dramatic seasonal shifts. These range from drought-dry flats to flood-immersed wetlands. The estuary stands as a dynamic, living classroom for research, conservation, and cross-border habitat stewardship.
Top Activities and Amenities
Visitor Center & Interpretive Exhibits
The Visitor Center at 301 Caspian Way is your launchpad into the estuary. Open Wednesday through Sunday, 10 a.m.–5 p.m., it hosts an immersive diorama of the estuary ecosystem. There are discovery drawers and interactive bird migration maps. You can borrow binoculars (with ID) and obtain trail maps. The helpful staff will orient your visit in both English and Spanish. The Clapper Rail Nest gift shop offers local artwork, nature-themed keepsakes, and supports the Friends of San Diego Wildlife Refuges.

Local Insight
For a truly serene experience, visit midweek during the early morning. The marsh glistens under soft, golden light and bird activity is most lively. Time your walk to reach the river mouth as the tide crisps the shoreline. Pack a hot drink. Settle onto the bench there to watch a pelican swoop low against the sunrise. Later, wander the Visitor Center’s native plant garden and linger over the wildlife stories displayed inside—then drive into Imperial Beach for a quiet lunch by the pier, letting the wetlands’ whispers follow you through your afternoon.
