Saguaro National Park West has some of the prettiest desert landscapes and the largest and most expressive cacti you’ll see anywhere on earth. Containing both desert floor and uplands, Saguaro Park West has hillsides covered with saguaro cactus. The uniquely folded mountain range running through the park creates an ideal microclimate for the saguaro forest to thrive. The elevation ranges from 2,180 ft. to 4,687 ft. and includes two bioclimates: desert scrub (desert floor) and desert grassland (upland). The saguaro has different columnar variations: crested saguaros are rare and quite striking looking, some saguaros have no arms, some have many arms, not all arms point upward, and saguaros can grow to be 40 feet tall. Saguaros are habitat for many types of winged creatures and the cactus wren makes its home inside of holes in saguaros.
