Washington Park Trailhead & East Verde River

The Highline Trail #31 offers an immersive journey through Arizona's Tonto National Forest, showcasing a dramatic shift in scenery from open, brush-filled hills with panoramic views of the Mogollon Rim to dense Ponderosa pine forests and red-earthed canyons. You'll encounter numerous creeks, some with small waterfalls, and navigate rugged, rocky sections that demand your full attention. Keep an eye out for wildlife like elk as you traverse this historic route, which was once used by settlers and even the famous author Zane Grey.

This difficult point-to-point hiking route spans an impressive 128.5 miles (206.7 km) with a substantial 14288 feet (4355 metres) of elevation gain, requiring an estimated 58 hours and 20 minutes to complete. It's best tackled by experienced backpackers during the spring or autumn to take advantage of more moderate temperatures and seasonal water sources. Be prepared for significant elevation changes, particularly around areas like Hells Gate Canyon, and remember that the trail averages around 6,000 feet above sea level.

Originally established in 1870, the Highline Trail #31 holds significant historical value and is now designated as a National Recreation Trail, with a large portion integrated into the Arizona National Scenic Trail. It's known for its challenging terrain, even hosting the Zane Grey Highline Trail 50 Mile Run ultramarathon. Water sources like Horton Springs, where water emerges directly from the rocks, provide crucial refreshment along this demanding and rewarding adventure.

Embark on the Railroad Tunnel via Arizona Trail, a moderate hike that guides you through diverse landscapes. You will cover 3.8 miles (6.2 km) with an elevation gain of 976 feet (298 metres), typically taking about 2 hours and 1 minute to complete. The route begins alongside the East Verde River, offering shaded sections and the chance to spot small waterfalls, before ascending through fragrant ponderosa pine forests.

For your visit, parking is generally available at the Washington Park Trailhead. The trail starts with a relatively flat section, often crossing the East Verde River on well-built wooden bridges. Be prepared for some steeper climbs, particularly in the final quarter-mile leading to the tunnel, where you might encounter loose gravel and fallen logs.

The highlight of this route is the impressive 70-foot incomplete Railroad Tunnel, a fascinating historical relic carved directly into the Mogollon Rim. As you hike, you will enjoy panoramic views of the Mogollon Rim and the surrounding Tonto National Forest. If you visit in early November, you might also catch the vibrant fall colors along the way.
