sun shines 300 days of the year on this alpine village.
Springtime in May and June produces the most rainfall. Summer brings warm and dry days with cool nights, resulting in mountainsides and valleys full of wildflowers. Starting in late September, there's always a chance for light snow. The Colorado Rocky Mountains tend to have constantly changing weather, so be prepared for anything!
