Hiawatha Mountain Bike Trail Montana

Hiawatha Mountain Bike Trail

Just imagine mountain biking a 15-mile historic railbed trail through cavernous train tunnels, across sky-high train trestles, past sparkling mountain creeks with deer, elk, moose, and endless views of the towering Bitterroots. The best part is—it’s all downhill!

Located just off I-90 on the Idaho / Montana border, The Route of the Hiawatha is a scenic section of abandoned rail-bed from the “Milwaukee Road” that the Taft Tunnel Preservation Society, Silver Country, and the U.S. Forest Service have turned into a world-class non-motorized trail in the area around the Montana and Idaho Border. In fact, this stretch has been called one of the most breathtaking scenic stretches of railroad in the country. This adventurous 13-mile trail takes mountain bikers (and hikers) through 10 cavernous tunnels and over 7 sky-high trestles. The first tunnel you pass through is the 1.8 miles long Taft Tunnel re-opened in 2001. This tunnel burrows 1.66 miles under the Idaho-Montana border

The trail is operated and maintained by the Taft Tunnel Preservation Society with fees collected from all users. A shuttle bus can transport you and your bike between trailheads.

The Route of the Hiawatha

In 1905, The Milwaukee and St. Paul Railway began looking for a route for their western extension over the Bitterroot Mountains. After five and a half months, exploring 930 miles, the railroad chose a route over St. Paul Pass. In laying out the route from the St. Paul Pass Tunnel the surveyors planned a line descending at a 1.7% gradient along the mountain slope. A big consideration in choosing this route was the potential for future traffic. This route down the St. Joe River offered exclusive access to huge quantities of old-growth white pine and cedar timber. Interpretive sign on the trail.

The Last Transcontinental Railroad

The Chicago, Milwaukee, and St. Paul Railway’s Pacific Extension survived for 71 colorful years. Racing silk trains sped along the route, and long, rumbling troop trains carried men and materiel through four wars. The Milwaukee’s famed electric locomotives hosted presidents and celebrities and showcased the streamlined Olympian Hiawatha passenger train. The Route of the Hiawatha Rail-Trail traces the most costly and difficult section of the railroad to build from Chicago to Tacoma. Today, thousands enjoy traveling over this scenic, historic trail helping keep alive the spirit of the Milwaukee Road.

The trail follows the trains and historians trace the history along the trail. When the Milwaukee Road abandoned its route over the Bitterroot Mountains, salvage companies stripped the line of all the rails, ties, signals posts, and everything else of value. The small fragments left behind are the remains of one of America’s proudest railroads. From 1907 to 1911 thousands of people lived, worked, and played in this secluded part of the Bitterroot Mountains. They constructed a railroad while leaving faint signs of their own passing. Today you may see archaeologists digging and sifting along the Route of the Hiawatha Trail looking for clues about people and places not found in written documents. Historical research and archaeological fieldwork help breathe life into the history of the Milwaukee Road years. Interpretive sign on the trail.

The St. Paul Pass Tunnel

The Milwaukee Road faced the daunting task of drilling a tunnel 23 feet high, 16 feet wide, and 1.7 miles long into Idaho. It was a damp, dark, dirty dig. After the approaches were prepared in 1906, and a faltering start in 1907, work began in earnest in 1908. East and west crews toiled around the clock in wet, miserable conditions, and at their best could tunnel 20 feet a day. A company official remembered that:

“Men were hard to keep as the work was disagreeable and hard. Several large veins of water were encountered and at times the working conditions were almost unbearable.”

It took 750 men—400 tunneling inside, 200 outside removing the dirt and rock, and 150 running the dig’s power plant yards—two and a half years to complete. The steam-driven electric power plant set up four miles away in Taft, Montana powered both ends of the dig. Compressed air provided safe, smokeless powder to the giant steam shovels that loaded the blasted, broken rock into electric rail cars for removal. Interpretive sign on the trail.
