The Tijuana River Valley Regional Park (TRVRP) provides a wide variety of year-round recreational opportunities within its 1800 acres that include a bird and butterfly garden, community gardens, multi-use open-space turf area, and five ball fields. The park is part of the Pacific Flyway and is bisected by the east/west flowing Tijuana River. The broad, flat flood plain provides an ideal environment to study the diverse vegetation communities that attract transient bird populations as well as herptile species — lizards, skinks, snakes, whiptails, frogs, and toads. More than 340 bird species have been recorded — that is two-thirds of all bird species recorded in the entire county! The meandering trail system provides a lush environment ideal for exploring, with the Nature Observation Area around Dairy Mart Pond providing a well-developed area to introduce the wonders of the natural world.
The north trailhead off Dairy Mart Road is the best place to park for visiting the Nature Observation Area, where there is an informational kiosk and the trails are well developed and compact. This area is people-friendly with benches along the trail as well as bird blinds perfect for watching the birds around North Dairy Mart Pond. In addition, a wooden boardwalk borders a nonnative grassland and southern willow scrub. Be on the lookout for snakes and other reptiles. You will see mixed-use trail-markers indicating the developed trails for your enjoyment.
The TRVRP is culturally and naturally rich. This southernmost part of the U.S.A. for centuries served as the fishing grounds by the Kumeyaay Indians. The flat river floor of this park consists of fill, alluvium, recent and old alluvial fan deposits, and terrace deposits. The area is prone to earthquakes and seasonal flooding. The diverse plant community includes: southern mixed chaparral, maritime succulent plants, native grasslands, coastal sage scrub, riparian plant communities, nonnatives, and disturbed habitat. The ponds and surrounding riparian wetlands provide habitat for songbirds, rails, waterfowl, and shorebirds.
