Interstate is a 21.2-mile out-and-back trail located in Arizona. With 436 feet of elevation gain, this is a relatively flat route suitable for hikers seeking a long-distance trek without significant climbing. The trail's modest elevation profile makes it accessible to a wide range of skill levels, though the distance demands good endurance and preparation. The out-and-back format means hikers will cover roughly 10.6 miles in each direction, allowing for flexible turnaround options if needed. This structure also provides the advantage of retracing a familiar path on the return journey. Before heading out, ensure you have adequate water, sun protection, and a reliable map or GPS device. Check current trail conditions and weather forecasts, as desert conditions can change rapidly. Start early to maximize daylight hours and allow ample time to complete the hike safely.
