Organ Pipe Cactus National Monument celebrates the life and landscape of the Sonoran Desert. In this desert wilderness, you may drive a lonely road, hike a backcountry trail, camp beneath a clear desert sky, marvel at magnificent cactus, or soak in the warmth and beauty of the Southwest. Leashed pets are allowed on the Palo Verde Trail, the Campground Perimeter trail and in developed areas, such as picnic areas, parking lots, and along gravel and paved roads. Leashes must be no longer than six feet. Pets are not allowed in the buildings and cannot be left unattended. Note that the temperature here is very hot, even in winter. Remember to bring plenty of water, and becareful - hot pavement can burn paws!
