Colorado means mountains and high-altitude skiing. The altitude guarantees snow in winter, and skiers can enjoy abundant of sunshine. Even though the altitude of the ski areas exceeds 10,000 feet / 3,000 meters above sea level, there is plenty of tree skiing. Most of the ski resorts in the Colorado Rocky Mountains have vertical drop that exceeds 3,000 feet / 900 meters. The largest resort is Vail, the most famous is Aspen. There are many others here, such as the renowned Beaver Creek, Steamboat with its high alpine ridges, the lesser-known Cooper Mountain and the Breckenridge resort with the highest chairlift in North America.
Vail did not exist until 1960's; today it is one of the largest skiable areas in the United States. It combines several mountains and many acres of backcountry skiing. Unfortunately it often becomes overcrowded because of its growing popularity.
Aspen is old mining village that become a ski town right after WWII. Ask anyone to name a ski resort in the United States and most likely Aspen will be one of them. This town is known as the upscale place visited by rich and famous, but skiing here is also one of the best. You have four ski mountains to choose from. The Aspen Mountain has a steep face right of the town, vertical drop is almost 1000 m/ 3300 ft. The most important is that there are no beginner trails and absolutely no lift lines. This is skiing without limits; simply ski here as much as you can!
