Weather InformationThe weather changes quickly throughout the year due to the state's location and varied terrain. However, temperatures rarely rise above 90 degrees in the summer or fall much below freezing in the winter. Greater snow accumulation in the mountains creates ideal conditions for skiing, while the valleys stay fairly mild and temperate. Summer months consist of clear skies interspersed with light rain.
Crowd InformationWith an annual visitation rate of more than 11.5 million during the winter season alone, ski resorts and slopes can be overcrowded. To avoid the crowds, try traveling between Thanksgiving and Christmas, or March through early April when things start to slow down. Although the summer attracts even greater numbers of visitors, it's less likely to feel crowded since warm weather activities are more spread out. During the low season, or what is referred to in the mountains as "mud season," tourists nearly vanish.
Closure InformationThere are no significant annual closures.
When to SaveDuring the summer months, many mountain resorts offer incentive packages. They usually include round-trip airfare, rental car, lodging, and a variety of outdoor activities such as horseback riding, bike tours, and whitewater rafting. Prices are typically lower during the low season.
When to BookWith twenty-three commercial airlines providing regular service to ten Colorado cities, keeping an eye on discounts and deals throughout the year can be very beneficial.
