The Route of the Hiawatha Bike Trail, often hailed as the “crown jewel” of rail-to-trail adventures, promises an unparalleled experience for cyclists and hikers alike. This spectacular 15-mile trail immerses you in the heart of the Bitterroot Mountains, guiding you through 10 historic train tunnels and across 7 breathtaking trestles. Imagine gliding through the iconic 1.66-mile St. Paul Pass Tunnel (also known as the Taft Tunnel), a highlight that marks the beginning of your journey along the crest of these majestic mountains near Lookout Pass Ski Area. The best part? The Hiawatha Trail is predominantly downhill, making it a family-friendly adventure accessible to everyone from young children to seasoned seniors, with convenient shuttle services available to return you to the top.
A Trail of Scenic Wonders and Railroad History
The Route of the Hiawatha isn’t just a bike trail; it’s a journey through history and breathtaking scenery. Once part of the Milwaukee Railroad, this route was celebrated as one of the most visually stunning stretches of railway in the nation. Historically, trains navigated 11 tunnels and 9 towering trestles across a 46-mile section through the rugged Bitterroot Mountains, connecting Idaho and Montana. The centerpiece, the St. Paul Pass Tunnel, extends for an impressive 8,771 feet (1.66 miles) beneath the mountains, right at the state line. This remarkable trail has earned its place as a “Hall of Fame” trail by the Rail-to-Trail Conservancy, a prestigious recognition shared by only 15 trails nationwide.

Exploring the Idaho Section: Tunnels and Trestles Await
The Idaho section of the Hiawatha Bike Trail, initially opened in May 1998, spans 13 miles of captivating terrain, inviting hikers and mountain bikers to explore its wonders. This section, stretching between Roland and Pearson, guides you through 8 open tunnels and across 7 sky-high trestles, following the natural contours of the mountainous landscape along the Loop Creek drainage. Notably, the portion from Moss Creek to Pearson is reserved for non-motorized traffic, ensuring a peaceful experience. The trail from Roland, located just below the West Portal of the St. Paul Pass Tunnel, to Pearson offers a gentle ride on an unpaved gravel road. Following the original railroad grade, this section descends at a comfortable 1.6% downhill grade, dropping from 4,160 ft. at the West Portal to 3,175 ft. at Pearson – a total descent of just under 1,000 feet over 13 miles. For those who prefer not to cycle back uphill, a scheduled shuttle bus service provides convenient transportation for riders and their bikes, returning you to Roland to easily access the St. Paul Pass/Taft Tunnel and the parking area at the East Portal.
Conquering the St. Paul Pass Tunnel: A Dark and Thrilling Passage
The grand opening of the St. Paul Pass, or Taft Tunnel for trail use occurred on June 23, 2001, marking a significant expansion of the Hiawatha experience. This immense, level, and dimly lit tunnel, cutting through the Bitterroot Mountains, serves as a unique connection between Idaho and Montana, stretching 1.66 miles in length. Motorized vehicles are prohibited within the tunnel, preserving its unique atmosphere. The primary parking area is situated at the East Portal of the tunnel, just 2 miles from Taft Exit 5 on I-90, easily accessible by following the signs. From the East Portal trailhead, the highest point of the trail, to the lower trailhead at Pearson, the total ride is approximately 15 miles.

With the St. Paul Pass Tunnel open, visitors have several access options. Parking at the East Portal (in Montana) and entering the Idaho section via the tunnel is the most common choice. Alternatively, for those wanting to bypass the tunnel, particularly in early summer before full snowmelt (typically around the first weekend in June), driving 5 miles via FS Road 506 over Roland Summit and parking at the Roland trailhead is a viable option. Inside the St. Paul Pass Tunnel, don’t miss the interpretive sign located mid-tunnel on the right wall, marking the Idaho/Montana state line and acknowledging the crew that first reached the tunnel’s center in 1907. Also, be sure to capture the beautiful waterfall at the West Portal of the tunnel – a perfect photo opportunity for your group.
Extend Your Adventure: Biking Towards the East Portal from Lookout Pass
For those seeking a longer ride, consider starting from the Lookout Pass parking lot (elevation 4,730 ft.). From here, the trail follows the old Northern Pacific railroad grade eastward for approximately 10 miles to the Taft Site (elevation 3,630 ft.). Along this scenic stretch, the trail crosses the St. Regis River three times, passes through a tunnel, and goes under Interstate 90 twice before reaching Taft. From Taft, the trail ascends gently at about a 2.1% grade for 2 miles to the East Portal of the St. Paul Pass, or Taft Tunnel (elevation 4,160 ft.).
Future Expansion: The Montana Section Beckons
Exciting developments are underway for the Route of the Hiawatha Bike Trail. With the St. Paul Pass Tunnel now open, plans are in progress to extend the trail another 31 miles eastward into Montana, reaching all the way to St. Regis. This future section is envisioned to include an additional tunnel and 2 trestles and will be accessible to bikers, hikers, all-terrain vehicles, horses, and even automobiles, promising even more adventure and exploration opportunities.
