Saguaro in October: what the park service says
October 1 puts Saguaro's visitor centers back on their longer hours, 9 a.m. to 5 p.m. daily. In the Rincon Mountains, two fires in 2020 burned high-elevation areas, and the park asks hikers there to stay on the trail: stump holes can leave weak ground, ash and pine needles make trails slick, and fire-weakened trees can still fall. Restrooms outside the Rincon Mountain Visitor Center are open around the clock.
