Perfect late-season powder is found at resorts a little farther north, at higher elevations, like @Banff & Lake Louise Photos & Video Alberta. Now is also the time to score prime last-minute ski deals.
Many people plan Colorado trips for ski season. Sometimes, it's cheaper to be there early in the season, before the serious ski rush begins. It might also be good to wait until late winter, when many nearby resorts still offer plenty of snow and reduced prices. Even non-skiers can enjoy a great deal of beauty in the winter months. Just be certain to plan ahead to allow for weather and road conditions.
