Located on the southwestern slopes of Mount Washington, Elyria Canyon Park is a 35-acre nature park that provides a glimpse into the native habitat that once thrived in the hills near downtown Los Angeles. A network of trails meanders through fragrant communities of coastal sage scrub, chaparral, grassland and purple needlegrass. The park boasts one of the finest examples of California black walnut woodland in Southern California. The trails lead to vistas of the Los Angeles River, Griffith Observatory, and the city.
