Frequently asked questions

What is the climate like for hiking in Colorado?

In Colorado, a hiker's paradise, weather conditions can vary greatly by season and elevation. Generally, the state experiences a sunny, dry climate, making it a year-round hiking destination.
Summer (June through August) offers the warmest weather and is typically the best time to tackle high-altitude hikes in the Rocky Mountains, as trails are mostly free from snow. However, afternoon thunderstorms are common, so early starts are recommended.
Winter (December through February) brings snow and cold temperatures, especially at high elevations, making some trails inaccessible. But for the prepared adventurer, winter hiking or snowshoeing can offer a unique and serene experience. Always check local weather conditions before setting out. For trail updates and weather info, visit the Colorado Parks & Wildlife website. [Link: https://climate.colorado.gov/]
