RNA - RESEARCH NATURAL AREA

Mount Lemmon is a 7.8-mile out-and-back trail located in Arizona's Research Natural Area wilderness. The hike features 1,706 feet of elevation gain, making it a moderate to challenging trek for hikers seeking substantial vertical distance. This trail takes you through protected Research Natural Area terrain, offering the opportunity to explore a designated wilderness zone with restrictions in place to preserve its ecological value. The out-and-back format allows you to turn around at your preferred point, giving flexibility for different fitness levels and time constraints. The elevation gain is distributed across the 3.9-mile approach to the turnaround point, providing a steady climb throughout the hike. This sustained ascent rewards hikers with significant elevation change over a reasonable distance. The return journey follows the same route, allowing you to retrace your steps on the descent. Mount Lemmon's proximity to Arizona makes it accessible for day hikers in the region. The Research Natural Area designation means the landscape remains relatively undeveloped, preserving the natural character of the wilderness experience throughout your hike.
