The park was created as part of the U.S. Army Corps of Engineers' flood control project to manage the San Gabriel River watershed.
It is home to the Whittier Narrows Nature Center, which serves as a gateway to over 400 acres of protected wildlife habitat.
The recreation area includes the El Monte Airport on its northern boundary.
The region is a designated Important Bird Area (IBA) due to its role in the Pacific Flyway migration route.
The park provides specific facilities for model airplane flying, including a dedicated airfield.
The archaeological site of the Tongva village, Toviscanga, is historically associated with this geographic area.
It features one of the few public archery ranges in the Los Angeles County park system.
Whittier Narrows Recreation Area is a sprawling 1,492-acre complex centered around the confluence of the San Gabriel and Rio Hondo Rivers. It features three primary bodies of water: Legg Lake, Center Lake, and North Lake, which are designated for recreational fishing. The area hosts the Whittier Narrows Nature Center, which offers interpretive exhibits on local flora and fauna. Sports facilities include equestrian trails, archery ranges, trap and skeet shooting ranges, and baseball fields. Its extensive trail network connects to the San Gabriel River Trail, facilitating long-distance cycling and walking. The site encompasses diverse ecosystems including riparian woodlands and native coastal sage scrub. It functions as a significant migratory stop for birds along the Pacific Flyway. Picnic areas are dispersed throughout the grounds, often equipped with shade structures.
The wooden footbridge spanning Legg Lake offers panoramic views of the water with the San Gabriel Mountains in the background.
Bring binoculars as the area is a prime location for birdwatching, particularly in the wetlands around the lakes.
Stay on marked trails to avoid sensitive habitat areas and protect local wildlife nesting grounds.
Check the county park website for local event closures if you plan to visit on a holiday weekend, as picnic areas are popular for gatherings.
Do not attempt to swim in the lakes, as they are not designated for recreational swimming and water quality varies.
Leash laws are strictly enforced for pets; packing out all trash is required to maintain the wildlife preserve.
