The Tijuana River Valley is a rural community in the southern section of San Diego. It neighbors Imperial Beach to the north and west, Egger Highlands and Nestor to the north, San Ysidro to the north, and the U.S.-Mexico border to the south. Major thoroughfares include Hollister Street, Monument Road, and Dairy Mart Road.
The Tijuana River Valley, along with other portions of South San Diego, was annexed from San Diego County in 1957.
The community contains 71.5 miles of dirt roads and paths.[1] A number of horse stables are located in the valley. The valley is home to the Tijuana River Valley Regional Park, and is near Border Field State Park and the Tijuana River National Estuarine Research Reserve, both located in Imperial Beach.
