How Long Does Mud Season Last in Colorado?
If you're planning a spring trip to the Colorado Rockies, you may have heard of something locals call "mud season." It’s that in-between time after ski season winds down and before summer hiking and biking hit full swing. But how long does mud season actually last in Colorado — and what should you expect?
What Is Mud Season?
Mud season refers to the transitional period in the Colorado high country when snow begins to melt, but trails and roads haven't dried out yet. It's exactly what it sounds like: muddy, slushy, and often unpredictable.
This season usually hits mountain towns like Aspen, Vail, Breckenridge, Telluride, Crested Butte, and Grand Lake hardest — places that rely on both snowfall and summer sun for their tourism economies.
When Does Mud Season Start in Colorado?
Mud season typically begins in late March or early April, right after the ski resorts start closing. This timing can vary based on elevation and how much snow the area received over the winter. In general:
Lower-elevation towns (like Boulder or Golden) may see early signs of mud season by mid-March.
High-altitude towns (8,000+ feet like Breckenridge or Grand Lake) usually enter mud season in April, once the spring thaw begins in earnest.
How Long Does Mud Season Last?
The short answer? Anywhere from four to eight weeks, depending on the weather.
Here's a general breakdown:

Unusually wet springs or heavy snowfall years can extend mud season into early June, especially in areas like the San Juan Mountains or the Gore Range.
What’s It Like During Mud Season?
Mud season isn’t just about messy boots — it’s also a shoulder season for Colorado’s tourism. That means:
Quiet towns: Fewer crowds and more room to explore.
Business closures: Many restaurants and shops reduce hours or close for a few weeks while locals take a break.
Great deals: Hotels, lodges, and vacation rentals often offer discounted rates.
Unpredictable weather: Sunshine, snow, and rain are all possible in the same week.
Should You Visit Colorado During Mud Season?
It depends on what you’re looking for. If you're hoping to ski powder or hike dry trails, mud season probably isn't ideal. But if you love peaceful landscapes, fewer tourists, and budget-friendly prices, it might be the perfect time.
Pro tip: If you're traveling during mud season, bring waterproof boots, check road conditions regularly, and avoid muddy hiking trails to prevent erosion.
Final Thoughts
So, how long does mud season last in Colorado? Plan for about six weeks, give or take. It’s not the most glamorous time of year, but it has its own charm — and offers a quiet, slowed-down version of Colorado that few tourists get to see.
