Bozeman to Bonners Ferry Road Trip Guide: Scenic Drive

On the winding 450-mile route from Bozeman, Montana to Bonners Ferry, Idaho, you'll follow US-191 north to I-90 west, then US-93 north across the Continental Divide twice. At milepost 67 on US-93, the road skirts the actual Kootenai River—Bonners Ferry's namesake ferry operated until 1947. This highway segment, built over ancient Native American trails, offers a rare glimpse of three distinct Rocky Mountain ecosystems in a single drive: the Gallatin Valley, the Bitterroot Range, and the Purcell Trench. Before you go, learn how to find the best stops and hidden gems between cities to maximize your journey.

With 2+ days, you can fully appreciate the changes in elevation—from 4,800 feet in Bozeman to 2,300 feet in Bonners Ferry. The route crosses three national forests (Gallatin, Lolo, and Kootenai) and skirts two major wild rivers, the Clark Fork and the Kootenai.

The Gallatin Valley near Bozeman features rolling hayfields framed by the Bridger Range. As you climb toward Butte, the landscape flattens onto the high plains, then drops into the Deer Lodge Valley. The Bitterroot Mountains rise abruptly west of Missoula, their granite peaks catching afternoon light. North of Lolo Pass, US-93 follows the Lochsa River through lush cedar-hemlock forests—a stark contrast to Montana's open ranges.
