Bidwell Park is “divided” by Manzanita Avenue. The area west of Manzanita Avenue is referred to as Lower Park and the area to the east is referred to as Upper Park. The noticeable difference between Upper and Lower Park is the terrain. Upper Park is located in the foothills of the Sierra Nevada Mountains. It has steep terrain and contains many rock formations, including the unique Chico Formation sandstone and Lovejoy Basalt rocks. Lower Park is flat and level with a thick canopy of trees which provide ample shade for the visitor.
