Visiting the San Diego National Wildlife Refuges
There are three main access points for visitors to learn about the wetlands and enjoy the wildlife. Select the links below for details on visiting the two nature centers and the state park.
Chula Vista Nature Center – This is the closest location to downtown San Diego. It is located very close to highway I-5 and rests along the eastern shore of San Diego Bay. Here you will see a bald eagle, two golden eagles, an aviary, aquarium, and a Discovery Center. Guided tours of the Nature Center and the local trails in the Wildlife Refuge are available.
Tijuana River Estuary Visitor Center – Located just past the south end of the San Diego Bay, the Tijuana Estuary Visitor Center is free to the public and provides a number of exhibits explaining the wildlife found in the surrounding Wildlife Refuge. There are walking trails where you can walk up to three miles through the Refuge. Guided bird walks and nature walks are provided on a weekly basis.
Border Field State Park – Visit the most southwestern corner of the United States. Just a few miles south of the Tijuana River Estuary Visitor Center, the Park is home to stark contrasts. To the north, you see the Wild Life Refuge extending up the coast with few signs of humans. Looking south, you see the International Border Fence and a hundreds of Mexicans at play on the beaches and at the Bull Ring Stadium.
