One of the most important factors that goes into choosing a ski resort in Colorado is price. Certain cities are more expensive than others, such as Aspen and Vale which are both considered "luxury" ski resort towns. Compare prices between resorts and check to see if they offer any promotional rates.
The location of a ski resort determines the type of skiing you will be doing. Check each resort to see what type of slopes they offer and for what level of skier.
Ski resorts in Colorado offer many amenities, but each resort is different. Some resorts may offer fireplaces while others provide free lift tickets. Research the amenities of ski resorts beforehand.
