Thunder River Trail

Managing agency

United States National Park Service

Thunder River Trail is a 24.2-mile out-and-back hiking route located in Arizona and managed by the United States National Park Service. The trail features 2,883 feet of elevation gain, making it a moderately strenuous option for experienced hikers. This backcountry trail offers hikers the opportunity to explore remote terrain within the national park system. The out-and-back format means hikers will travel the same route returning to the trailhead, covering approximately 12.1 miles one way to reach the turnaround point. The elevation gain is distributed across the route and should be factored into trip planning, particularly for those less accustomed to sustained climbs. The trail's distance and difficulty level make it best suited for day hikes by very fit hikers or overnight backpacking trips. Hikers should come prepared with adequate water, sun protection, and navigation tools. Check with the National Park Service for current trail conditions, any seasonal closures, and permit requirements before planning your visit.
