Hiking
The Tijuana Estuary offers a truly special hiking experience, immersing you in one of Southern California's last natural coastal wetlands. You'll wander through varied habitats like salt marsh and sand dunes, enjoying expansive views of the wetlands and the Pacific Ocean, especially near the river mouth where the Tijuana River meets the sea. The terrain is mostly flat, with a mix of dirt, gravel, and sandy paths, making it a gentle 5.6-mile (9.0 km) journey perfect for wildlife spotting, particularly for the over 370 bird species that call this area home.
Planning your visit is straightforward, with a visitor center available to help you get oriented. If you plan to explore the sandy sections, especially on the Coast Trail, it's a good idea to check tide schedules for easier walking on harder-packed sand. The trail is generally accessible and takes about 2 hours and 16 minutes to complete, with a minimal 57 feet (17 metres) of elevation gain, making it a moderate and rewarding outing for most hikers.
This isn't just any coastal walk; the Tijuana Estuary is a designated "Wetland of International Importance," serving as a critical breeding, feeding, and nesting ground along the Pacific Flyway. Its unique geographical position at the southwestern tip of the United States, bordering Mexico, adds to its distinct character. It stands out as one of the few remaining natural estuaries in a region where over 90% of coastal wetlands have been lost to development.
