Steamboat's slopes open from November to April, but to catch the biggest dumps and best bluebird days, head here between January and March. Powder party! Steamboat is home to some of the best champagne snow in the US, so try to avoid the big local holidays if you don't want to queue for that super peachy powder. If you're a fan of apres-ski entertainment, Steamboat's event calendar is jam-packed throughout the winter. Highlights include the Cowboy Downhill skiing comp, Winter Carnival, and WinterWonderGrass Music Festival, to name a few.
