Getting to Lost Trail Powder Mountain is easy. Conveniently located just 1/8 of a mile off Hwy 93 and Hwy 43 at the Montana-Idaho border. We are easy to get to from just about any location. Enjoy the pristine view of the Bitterroot Mountains on your 90 mile trip from Missoula or 100 miles from Butte. From Salmon and surrounding areas it’s just about 45 minutes until you’re heading down the fun filled slopes!
