Tijuana River National Estuarine Research Reserve
Tijuana River National Estuarine Research Reserve is a natural reserve encompassing the Tijuana River Estuary, located on the Mexico – United States border, in Imperial Beach, California.
It can be accessed from the Coronado Avenue exit (Exit 4) from Interstate 5. It is established as part of the National Estuarine Research Reserve system in the United States and managed in part as a Biological Field Station by San Diego State University (SDSU)'s College of Sciences. The water flow of Tijuana River is often intense; droughts dry up the river completely while the same area overflows during flood.
This reserve is a good place for bird-watching since as many as 370 bird species, whether they're native or migrating, use it as a stopover or breeding. Schoolchildren often come to this reserve to take nature classes in classrooms and excursions. Visitors of all ages can come to the visitor center for activities. Among the activities are videos that can be shown upon request, and it is shown in both English and Spanish. Guests can also take a walk on North and South McCoy trails, where they can access primary bird-watching areas and the mouth of Tijuana River, where it empties directly into Pacific Ocean.
