Winter is coming. Winter peak season in Colorado, that is, which is in full swing from November to March. To prepare, Oyster's reporters visited nearly 100 properties across the state to find the very best ski resorts. Their findings? Classic mountain lodges with direct chairlift access and ski valet services, hotels with hot apres-ski scenes and outdoor pools heated year round, and group-friendly condo and cabin complexes. Check out our picks for the top ski resorts in Colorado. (Lobbies with huge stone fireplaces were pretty much non-negotiable; spas with steam caves optional).
