Colorado Winter Guide
Colorado's ski season, mountain-town winter culture, and non-skiing options — from snowshoeing and hot springs to cozy lodge evenings.
Overview
Winter in Colorado means snow from November through April, peak ski season from December through March, and a broad range of activities beyond downhill skiing. The state has 28 ski areas, the largest concentration in the US, ranging from world-class resorts (Aspen, Vail, Telluride) to family hills (Loveland, Echo Mountain) and backcountry zones. Non-skiers can enjoy snowshoeing, fat biking, hot springs, sledding, ice skating, holiday events, and mountain-town culture.

Road Conditions

Altitude Note
Ski resort base elevations range from about 8,000 feet (Breckenridge) to 10,780 feet (Arapahoe Basin). Above-treeline skiing (Breckenridge Peak 6, A Basin) exceeds 12,000 feet. Acclimatize in Denver or a lower town first, hydrate aggressively, and watch for altitude sickness symptoms.
