A dream road trip requires not only cool destinations but inspiring travel along the way. Ask dedicated skiers and snowboarders what their dream trip looks like and you’re bound to hear the phrase “Powder Highway” come up more than once. The 630-mile stretch runs along Route 95A through British Columbia and into Alberta, with dozens of ski resorts and even more options for backcountry touring en route. South of the border, the US has a similar stretch of road – albeit one that runs north to south without nearly as much fanfare: US Highways 191 and 89 from Bozeman, Montana, to Ogden, Utah.
