The Route of the Hiawatha is one of the most spectacular rail-to-trail paths in the United States, stretching across the rugged mountains of the Idaho–Montana border. Once part of the historic Milwaukee Road railroad line, it has been transformed into a world-class biking and hiking trail, celebrated for its dramatic scenery, engineering marvels, and rich history. The route takes travelers deep into the Bitterroot Mountains, offering a journey that is as much about discovery and adventure as it is about recreation.
What makes the Route of the Hiawatha especially unique is its series of tunnels and trestles that wind through the remote backcountry. Riders pass through ten tunnels, including the legendary 1.66-mile-long St. Paul Tunnel, and cross seven high steel trestles that soar hundreds of feet above forested valleys. Each structure is a reminder of the incredible effort it took to carve a railroad through such challenging terrain in the early 20th century. Today, these features provide unforgettable thrills and breathtaking perspectives of the surrounding wilderness.
The trail itself is about 15 miles long, sloping gently downhill, which makes it accessible for families, casual cyclists, and outdoor enthusiasts alike. Shuttle services are available to bring riders back to the start, allowing them to focus solely on the beauty of the experience. Along the way, interpretive signs share stories of the railroad, the people who built it, and the natural environment of the Bitterroots, adding depth and context to the journey.
Surrounded by alpine forests, wildlife, and sweeping mountain vistas, the Route of the Hiawatha is more than just a trail—it’s a living museum of railroad history and a gateway to some of the Northwest’s most striking landscapes. Whether pedaling through cool, damp tunnels or gliding across trestles with panoramic views, visitors find themselves immersed in both nature and history. It’s a destination that blends adventure, education, and natural beauty, making it one of Idaho and Montana’s most treasured outdoor experiences.
