Lolo Pass: Following the Lewis and Clark Trail on Two Wheels

Lolo Pass, on the border of Montana and Idaho, is one of the most historic and scenic mountain biking destinations near Missoula. Following the Lewis and Clark National Historic Trail corridor, this ride combines challenging climbing, dense forest, and a deep sense of history.

The Historic Significance

Lolo Pass is where the Lewis and Clark expedition crossed the Bitterroot Mountains in 1805. The Nez Perce also used this route. Today, you can ride the same corridor that these historic figures traveled, following Forest Service roads and trails through the rugged Bitterroot Mountains.

The Ride

The main ride follows Forest Service roads up to Lolo Pass, gaining significant elevation over about 9 miles. The climb is steady and challenging, with dense subalpine forest surrounding you. At the pass, you're rewarded with mountain scenery and a sense of accomplishment.

Trail Conditions

Lolo Pass is at high elevation, so snow can linger well into June. The best riding is from July through October. Check conditions before you go, as the road can be closed due to snow or logging activity.

Connecting to Idaho

From the pass, trails continue into Idaho, offering extended rides for adventurous mountain bikers. The Lolo Motorway, a historic road along the ridgetop, offers miles of riding with stunning views.

Getting There

Lolo Pass is about 45 minutes southwest of Missoula. Take US-12 west through Lolo to the Lolo Pass Visitor Center. The ride starts from the visitor center parking area.

Gear and Preparation

This is a backcountry ride — carry bear spray, extra food, water, and layers. The weather at the pass can be dramatically different from Missoula. Tell someone your plans and expected return time.
