Straddling the Idaho–Montana border in the Bitterroot Mountains, Lost Trail serves up glades, cliffs, and pillow lines—and deep, dry snow. Because Lost Trail is closed Monday through Wednesday, when the lifts start spinning on Thursday, the whole place is untracked. The resort has an old-school vibe and it’s not uncommon to see travelers camping in the parking lot and bag lunches in the cafeteria. There isn’t a scene really—no lodging or restaurants—just tons of snow. If only the rest of life were this simple.
