Saguaro National Park is divided into two sections; the eastern Rincon Mountain District and the western Tucson Mountain District. The two districts are separated by the city of Tucson. We had planned to visit both sides, but only made it to the eastern Rincon District. Our next stop was the Grand Canyon, and snow was expected, so we decided to head out early and give ourselves plenty of time to make the commute in the daylight. The park protects the largest variety of cactus in the U.S., the Giant Saguaro. The Saguaro can live for 150 years, grow over 40 feet tall, and weigh in at over a ton. Let me say that pictures do not do these giants justice, they are huge. If you are a fan of desert landscapes and flora, I highly suggest taking yourself to Arizona to experience these giants in real life. Be prepared if you plan to take off for a hike in the cactus forest. It was hot here in November and the trail system is a bit confusing. We ended up hiking twice the distance we intended and barely made it back to the trailhead before dark. My advice is to hike early in the day and bring plenty of water with you.
