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.
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.
