When to Visit Colorado: The Best (and Worst) Times for Every Region

One of the best things about Colorado is the ever-changing weather throughout each season. Locals know all too well, it can be sunny and 65°F one minute, snowy and 30°F the next, and then wrap up with a stunning sunset over a crisp 45°F evening.

This unpredictability means no two days are the same—but it can make planning your trip a bit tricky. When’s the best time to visit? Where should you go, based on that visiting season?

Let’s break it down, so you can have a better idea on when the best (and worst) times to visit are, based on the region you’d like to see.

It’s no secret that Colorado is a beautiful state to visit, no matter what time of year you visit. 

Winter turns the state into a snow lover’s paradise, with world-class skiing, ice fishing, snowmobiling, and sledding. 

With springs arrival, you’ll find some excellent snowfall in the mountains—perfect for late-season skiing—while the lower elevations burst to life with blooming flowers and budding trees. 

In summer, Colorado shines with endless blue skies, outdoor concerts, rafting, biking, hiking, and adventure around every corner. 

Come fall, the air cools, the aspens turn gold, and the trails are ideal for crisp hikes and scenic drives. Festivals pop up statewide, celebrating everything from harvests to craft beer.

Whether you're here to experience the iconic Red Rocks Amphitheatre or want to soak up the city vibes, think funky shops, legendary green chili, and vibrant neighborhoods. There’s plenty to keep you close, and Denver and its surrounding towns deliver a lot right from the start.

Best times to visit: April–June; late September–early November

Spring and fall bring pleasant temperatures, fewer tourists, and great weather for exploring parks and day hikes.

Worst times to visit: July–August; December–May

Summer brings hot days, smoky air from wildfires, and heavy crowds. Winter can mean icy roads, unpredictable weather, and travel delays.

Colorado has the largest collection of 14ers in the country with 58 peaks in total. Mountain ranges like the Sangre de Cristo, Sawatch, San Juans, and White River Plateau make up this rugged alpine playground. Each year, visitors come to ski, hike, raft, camp, and climb among these towering peaks.

Best times to visit: June–early October; late December–early March

Summer offers ideal weather for outdoor recreation, and early fall lights up the mountains with golden aspen groves. Winter is prime for skiing, snowmobiling, and ice fishing.

Worst times to visit: late March–May; November–early December

Spring in the mountains is mud season. Trails are soggy, weather unpredictable, and snow conditions inconsistent. It is too warm for great skiing and too cold for comfortable hiking.

From rafting and hiking to hunting and fishing, this region delivers some of Colorado’s best outdoor recreation along with fascinating history. Mesa Verde, Chimney Rock, and ghost towns scattered through the San Juans add plenty to explore.

Best times to visit: June–early October; late December–March

Summer is less crowded than the Front Range or the I-70 corridor but offers equally great adventure. Fall adds stunning color as aspen groves turn gold across the mountains.

Worst times to visit: April–May; late October–November

Both spring and late fall bring cooler, less predictable weather and muddy conditions that make hiking and camping less enjoyable.

If you’re craving a break from the high peaks or city rush, the Western Slope delivers mild winters, desert landscapes, and world-class biking and hiking.

Best times to visit: March–May; September–December

Spring brings blooming orchards and mild temperatures, while fall celebrates wine country tours and peach festivals. Even in winter, the weather stays relatively comfortable for outdoor fun.

Worst times to visit: June–August

Expect desert heat that regularly tops 100°F. Plan outdoor activities early in the morning or later in the evening when temperatures cool.

This often-overlooked region holds some of Colorado’s most surreal landscapes. The Great Sand Dunes rise before snowcapped peaks, while small towns, hot springs, and dark night skies offer a peaceful escape from the crowds.

Best times to visit: April–early June; September–late October

Spring brings Medano Creek’s flow through the dunes and colorful wildflowers, while early fall adds crisp weather, hunting opportunities, and bursts of foliage.

Worst times to visit: July–August; December–February

Summer heat can be intense, especially on the dunes. Winter brings biting cold and wind, making it less ideal for camping or long hikes.

Knowing when the best time to plan your trip will be based on several factors, including what you’re planning on doing and seeing while you’re here, and whether you will be with kids or pets.

Ultimately, the best thing to do is plan ahead and book things early. Stay up-to-date with wildfire and snow reports, and be prepared to be flexible; you never know when Colorado is going to throw you for a loop.
