Tijuana National Estuary

 The Tijuana Estuary is the largest coastal wetland in Southern California and it is located on the international border between the U.S. and Mexico. Border Field State Park is located within its boundaries. The estuary is primarily a shallow water habitat, however it is considered an "intermittent estuary," as drought can leave areas dry during some times and the same areas can be flooded during other times of the year.   

The Tijuana River Estuary is one of the few salt marshes remaining in Southern California, where over 90% of wetland habitat has been lost to development. Over 370  species of birds visit the estuary, which is considered a stopover on the pacific Flyway.  

When I visited it was relatively dry, and unfortunately the visitor center was closed.
