Mary Jane—named for a mining-era lady of the night—and its sister area, Winter Park, offer plenty of prospects for good skiing, including bumps and powder-filled bowls. Forming one of the closest major resorts to Denver, the two areas spread across five mountains and 3,078 acres. Add 3,060 feet of vertical, 30 feet of snowfall, and a direct train from Denver and it’s no wonder why the Front Range packs the place on Saturdays.
