Saguaro National Park in Tucson Arizona protects the nations largest cacti-the giant saguaro. These cacti can live over 200 years and can reach 40 feet tall. They are only found in this region, although the park is divided into two distinct districts (east and west). The Tucson Mountain District (West) offers dense saguaro forests and gravel drives, while the Rincon Mountain District (East) is a larger, more mountainous landscape with paved scenic drives .
