Trails
Hidden Valley Adopt-A-Trail
Hidden Valley Wildlife Area is located along the Santa Ana River, east of Norco on Arlington Avenue, one mile west of La Sierra Avenue. It is set on 1500 scenic acres and has access to 25 miles of hiking and equestrian trails. Visitors can get away from the noise and lights of the city and enjoy the beautiful views of the river or the bluff overlooking the wetland pond. In the winter, Canada geese, northern shovelers, white-crowned sparrows and yellow-rumped warblers make their home here.
