San Ysidro

San Ysidro is a community of San Diego, California. Although administratively part of the City of San Diego, San Ysidro is geographically separated from the rest of the city by the entities of Chula Vista and National City just to the north. San Ysidro is often cited as the world's busiest land border crossing, where U.S. Interstate 5 crosses into Tijuana, Mexico.

In addition to San Ysidro, the neighborhood close to the border crossing, this article includes adjacent neighborhoods in South San Diego: Otay Mesa area, Palm City, and the Tijuana River Valley.

You can drive to the border crossing and then continue driving through, or park at one of the lots and walk through. Parking at one of the lots costs about $4-9 a day. Traffic is pretty heavy coming up from Mexico.
