Tucson, Arizona is home to the nation's largest cacti. The giant saguaro is the universal symbol of the American west. These majestic plants, found only in a small portion of the United States, are protected by Saguaro National Park, to the east and west of the modern city of Tucson. Here you have a chance to see these enormous cacti, silhouetted by the beauty of a magnificent desert sunset.

Conditions
Rideshare services will drop visitors off at the park, but usually will not pick them back up. To avoid being stranded in the park, coordinate two-way trips before using rideshares to visit the West side. No major trails start at the visitor center.
As the busy season ramps up, traffic will be denser and can result in delays and complications particularly for owners of longer vehicles. The Tucson Mountain District (west side) of the park can accommodate vehicles up to 40ft in total length on the loop drive and has RV parking available at the Visitor Center, and the Rincon Mountain District (east side) can accommodate vehicles up to 40ft in length on the loop drive but has no RV parking available at the Visitor Center.
Vehicle break-ins have occurred at the King Canyon Trailhead, as well as at other trailheads throughout the park. Hide valuables and consider taking them with you, secure your vehicle, and report any suspicious activity. Please call 911 to report criminal activity or the Pima County Sherriff's Department Non-Emergency number at 520-351-4900.

FAQ
Saguaro is least crowded in July, August, and September. March is the busiest month, so visiting outside it means thinner crowds and easier parking.
Entrance to Saguaro costs $25 (The vehicle entrance pass is sold in the form of a dated register receipt and admits one privately owned, non-commercial vehicle into Saguaro National Park. This includes passenger cars, trucks, vans, recreational vehicles, campers, or converted buses used for private, recreational purposes.).
Saguaro is busiest in March, when crowds rate 10/10 (peak). Expect full parking lots and longer waits; arrive early or choose a quieter month.
