Great Falls to West Wendover Road Trip: Scenic Highways and Hidden Gems

This route along I-15 South and I-80 West crosses over 900 miles of diverse terrain, from the Missouri River headwaters to the Great Salt Lake Desert.

The drive takes roughly 12-14 hours of pure driving time, but with recommended stops, plan for two days.

The journey includes sections of old US-91 and historic railroad corridors, offering glimpses into the region’s mining and pioneer past. The route is predominantly interstate, but rural stretches require careful planning for fuel and food.
