Saguaro National Park splits into two districts flanking Tucson — the Rincon Mountain District (East) at 3693 S Old Spanish Trail, Tucson, AZ 85730, and the Tucson Mountain District (West) at 2800 N Kinney Rd, Tucson, AZ 85743. Combined, the park protects over 91,000 acres of Sonoran Desert landscape and the densest concentration of saguaro cacti on earth. The East district's Cactus Forest Loop Drive is paved and open to vehicles, including buses, during park hours.
Entrance costs $25 per vehicle (or $80 annual pass), and the park service recommends arriving before 9 a.m. in spring when wildflower season draws peak crowds. Bus parking in the East district is at the visitor center lot on Old Spanish Trail. For school groups and nature tours, a charter bus with undercarriage storage handles the lunch coolers and gear while keeping the group together on a single itinerary across both districts.
Check the NPS Saguaro visitor page for current entrance details.
