Bonners Ferry to Lander Road Trip Guide

The drive from Bonners Ferry, Idaho, to Lander, Wyoming, covers roughly 690 miles and typically takes 11–12 hours of pure driving time, but plan for at least two days to appreciate the scenery. This route crosses the northern Rockies and the high plains, offering a dramatic shift from cedar forests to sagebrush steppe.

Winter driving from November to March demands traction tires: chain laws are enforced in Montana and Wyoming passes. Summer brings sudden thunderstorms, especially along the eastern slopes of the Rockies; hail can occur without warning. Always carry water and a spare tire; remote stretches have limited cell service.

For families, the Museum of the Rockies in Bozeman has dinosaur exhibits and a planetarium; the Teton County Fair in Jackson Hole runs in July. Pets are welcome at many national forests, but require leashes; most motels along I-90 are pet-friendly, but call ahead. To fight fatigue, plan stops every 2–3 hours; noteworthy rest areas include the Madison River overlook at Three Forks, MT, and the Wind River Canyon viewpoint south of Thermopolis.

Hidden spots include the ghost town of Garnet, Montana, and the Hot Springs State Park in Thermopolis, where you can soak in free mineral pools. For finding more obscure gems, use how to find the best stops and hidden gems between cities.

Fuel stations are plentiful along the interstates (I-90 and I-25), but once you leave the interstate in Wyoming, they become sparse—fill up in Thermopolis before heading to Lander. Gas prices vary; Montana generally has lower fuel taxes than Idaho or Wyoming, so consider topping up in Butte or Bozeman.

• Road quality is good on interstates; secondary roads like US-20 in Wyoming are well-maintained but can be narrow in mountain passes.
• Cellular coverage is reliable in towns but spotty in mountain stretches; download offline maps.
• No tolls on this route.
• Rest areas are available every 50–100 miles on interstates, but some are seasonal in winter.

The route runs through the Bitterroot Valley, a region of jagged peaks and wild trout streams, then crosses the Continental Divide at Homestake Pass (elevation 6,329 ft). As you enter Wyoming, the Wind River Range dominates the horizon, with glacial lakes and granite summits over 13,000 ft. Yellowstone National Park is a detour about 180 miles north of the route, but it contains the only UNESCO World Heritage Site within a day's drive—Old Faithful.

Local commerce along the way includes family-run ranches selling bison jerky, small-town diners like the Ox Bow Cafe in Wisdom, MT, and the historic Moss Mansion in Billings. In Cody, WY (about 100 miles north of Lander), the Buffalo Bill Center of the West showcases western art and firearms. For unique souvenirs, stop at the Montana Grizzly Encounter near Bozeman, a bear rescue center.
