Helena to Hope: Montana's Scenic Highway to Idaho Lakes

Helena, Montana's capital, sits at 4,000 feet. Hope, Idaho, nestles on Lake Pend Oreille. The 289-mile route on I-90 takes about 5 hours without stops. You cross the Continental Divide at Lookout Pass, 4,700 feet. This drive pierces the Bitterroot Range, where Lewis and Clark struggled in 1806.

The route follows the Clark Fork River for miles. You pass the historic town of Missoula, home to the University of Montana. Beyond, you enter the Coeur d'Alene mining district. The road quality is excellent, but winter snow can close Lookout Pass.
