Hidden Valley Wildlife Area
Our Nature Center remains are closed until further notice due to COVID-19 restrictions.
Portions of our nearby multi-use trails previously damaged by fire remain closed.
Hidden Valley Wildlife Area is located along the Santa Ana River, east of Norco at 11401 Arlington Avenue, one mile west of La Sierra Avenue, in Riverside, CA. It is set on 1,500 scenic acres and has access to 25 miles of hiking and equestrian trails. Bicyclists also have the opportunity ride along the 8 mile stretch of the Santa Ana River Trail that links the San Bernardino Mountains to the Pacific Ocean. Visitors can get away from the noise, lights of the city, and enjoy the beautiful views of the river or the bluff overlooking the wetland ponds set aside for migratory birds. Picnic areas and a self-guided Nature Trail await visitors along with various seasonal events and nature education outreach programs.
The Hidden Valley Nature Center overlooks the Santa Ana River watershed and offers hands-on experiences with live animals, snakes, reptiles. A short hike to the educational pond offers viewing of migratory bird species, flora and fauna, and aquatic life.
