15 Common Colorado Trail Backpacking Mistakes (And How to Avoid Them)

When I first started researching the Colorado Trail, I spent hours comparing backpacks, tents, sleeping pads, shoes, and water filters. But the deeper I got into the planning process, the more I realized that things like timing, transportation, altitude, weather, and mileage planning can have a much bigger impact on your trip than whether you chose the perfect backpack. Ultimately, I came to this conclusion:

Bad Planning leads to more problems than bad gear does on the Colorado Trail.

I’ve spent a lot of time reading trail reports, watching videos, talking with hikers, and building my own long-term plan for backpacking the Colorado Trail in sections. So if you’re planning your first Colorado Trail trip, or even an experienced backpacker, here are 15 common CT mistakes I’ve found.

1. Starting the Colorado Trail Too Early

One of the first things I learned is that “summer” doesn’t mean the same thing in the Colorado high country as it does everywhere else. When most people think about backpacking season, they think June through September. But portions of the Colorado Trail spend a lot of time above 10,000 feet, and snow can linger surprisingly late into the year. And a date that works perfectly one year may be completely different the next depending on winter snowfall and spring weather, or even the sections that you plan to hike.

How to Avoid It

Don’t plan your trip based solely on the calendar. Before finalizing dates, check current snowpack reports, recent trail conditions, and hiker updates. The Colorado Trail Foundation and hiking groups are great resources for current information. Starting later is usually a lot more enjoyable than spending your vacation post-holing through snow. The trail will still be there in a few weeks, so it’s ok to wait for better weather.

2. Underestimating Altitude

As someone who lives in Tennessee, this is one of the things that concerns me the most. I can train for distance, and I can train for elevation gain, but what I can’t train for at home is sleeping (or hiking) at 10,000 feet.

Many hikers arrive in Colorado feeling strong and ready to go, only to find themselves dealing with headaches, fatigue, poor sleep, or nausea within the first day or two. Altitude affects everyone differently, and fitness doesn’t make you immune.

How to Avoid It

If your schedule allows, arrive a day or two early and spend some time acclimating before hitting the trail. More importantly, keep your expectations realistic during those first few days. Drink plenty of water, eat regularly, and don’t be surprised if your pace is slower than expected, or get out of breath easier than you think you should.

3. Letting Your Ego Plan Your Mileage

This might be the biggest mistake on the entire list. When planning a trip, it’s easy to look at the map and think, “I can do twenty miles a day.”, and maybe you can. The problem is that your body doesn’t care what looked good on a spreadsheet six months ago. Most experienced hikers I’ve talked to recommend the same thing: start slower than you think you need to.

How to Avoid It

Build flexibility into your itinerary. A conservative plan that leaves room for adjustment is usually better than a perfectly optimized schedule with no margin for error. Remember, the goal isn’t to impress anyone with your mileage. The Colorado Trail doesn’t care.

The goal is to enjoy the trip and finish healthy.

4. Doing Too Many Miles Too Soon

This sounds similar to the previous mistake, but it’s slightly different. Even hikers who know they should pace themselves often get caught up in the excitement of starting the trail. The first day feels great. The second day feels pretty good. Then Day Three arrives and suddenly your feet, knees, shoulders, and hips start filing complaints.

How to Avoid It

Think of the first few days as an investment. Give your body time to adapt to the altitude, pack weight, and daily effort. You can always increase mileage later if you’re feeling strong. It’s much harder to recover from starting too aggressively than it is to build up your “hiking legs”.

5. Carrying Your Fears Instead of Carrying Gear

I love this phrase because it perfectly describes what many of us do when planning our first big backpacking trip: We pack for every possible scenario.

What if it snows? What if my tent breaks? What if I need three backup systems for every piece of gear? Before long, the pack weighs forty pounds because of all of your “what if” gear.

How to Avoid It

Every item in your pack should earn its place. If you haven’t used something on previous trips and it doesn’t contribute directly to safety or comfort, consider leaving it behind. The Colorado Trail is still just backpacking. It’s not an expedition to Antarctica.

6. Waiting Too Long to Get Below Treeline

Before researching the Colorado Trail, I spent more time thinking about bears and bugs than thunderstorms. Now it’s the opposite. Lightning is one of the most serious hazards many Colorado Trail hikers will encounter. Large sections of the trail spend time above treeline where there is little or no protection from storms.

How to Avoid It

Start your hiking day early. Many experienced hikers will start as (or before) the sun comes up, and aim to be off exposed ridges before afternoon storms begin building. The earlier you start, the more flexibility you have if bad weather develops.

7. Assuming Every Water Source Will Be Flowing

At home, we rarely think much about water. On the Colorado Trail, that’s a mistake. Water availability can change dramatically throughout the season, particularly during late summer and fall. A stream shown on a map may not always be flowing when you arrive.

How to Avoid It

Research current conditions before your trip and always know where your next reliable water source is located. Carry enough capacity to handle unexpected dry stretches. Never assume water will be available simply because a map says it should be.

The FarOut app is a great resource for keeping up with current water conditions on the CT, and so is Facebook. People are regularly posting about the current trail and water situations.

8. Not Having a Transportation Plan

Transportation is one of the least exciting parts of trip planning. It’s also one of the most important. Many section hikers spend weeks planning their route but only a few minutes thinking about how they’ll actually get to and from the trail.

How to Avoid It

Figure out transportation before finalizing your itinerary. Think through parking, shuttle services, pickup locations, flight schedules, rental cars, and backup plans. Logistics may not be glamorous, but they can make or break a trip.

9. Packing for Average Weather Instead of Actual Weather

One thing I’ve learned from reading Colorado Trail reports is that average weather doesn’t tell the whole story. You might experience sunshine, wind, rain, hail, and freezing temperatures all within the same twenty-four-hour period. Colorado Trail weather has a reputation for changing quickly for a reason, especially out on the CT.

How to Avoid It

Plan for conditions, not averages. Make sure your clothing and shelter systems can handle a wider range of weather than the forecast suggests. Hope for perfect weather, but be prepared for something less cooperative.

10. Treating the Colorado Trail Like One Giant Trail

The Colorado Trail is often talked about as if it’s one continuous experience. It’s not. The trail changes dramatically from section to section. The first miles outside Denver feel very different from the Collegiate West. The Collegiate West feels very different from the San Juans.

How to Avoid It

Research the specific sections you’ll be hiking. Understand the terrain, elevation profile, weather patterns, water availability, and transportation challenges unique to that part of the trail.

11. Not Practicing With a Fully Loaded Pack

This is a mistake I’m actively trying to avoid myself. A backpack that feels comfortable in your living room can feel very different after ten miles on the trail.

How to Avoid It

Train with the actual gear you’ll carry. Load your pack to trail weight and use it on local hikes before your trip. You’ll quickly discover potential issues while you’re still close to home.

12. Flying In and Starting the Next Morning

This is especially relevant for us hikers traveling from out of state. Long travel days are tiring. Add altitude into the equation and you may begin your trip already behind the curve.

How to Avoid It

If possible, build an extra day into your schedule. Use that time to rest, hydrate, organize gear, and adjust to the elevation before starting your hike.

13. Not Understanding How Thunderstorms Affect Your Schedule

Most hikers know Colorado gets afternoon thunderstorms. What surprised me is how much those storms influence every aspect of trip planning. Wake-up times, campsite selection, daily mileage goals, and route choices are all affected.

How to Avoid It

Don’t just check the weather. Build your itinerary around it. Understand where you’ll be during the most exposed portions of each day and adjust accordingly.

14. Choosing Dates Based on Vacation Time Instead of Trail Conditions

Let’s be honest, most of us have limited vacation time. It’s tempting to choose a week that fits our work schedule and hope conditions cooperate. Unfortunately, nature doesn’t always check our calendars.

How to Avoid It

Whenever possible, choose your hiking dates based on trail conditions first and vacation schedules second. A slightly less convenient week may provide a dramatically better experience.

15. Spending More Time Researching Gear Than Planning the Trip

If you’ve made it this far, you may recognize yourself in this one. I know I do. It’s fun to compare tents, backpacks, sleeping pads, and gadgets. It’s a lot less exciting to research food, transportation options, weather patterns, and trail logistics. But those planning details often have a much bigger impact on the success of your trip.

How to Avoid It

Spend as much time planning your trip as you do planning your gear list. The best backpack in the world won’t help if your itinerary is unrealistic, your transportation falls through, or you’re caught unprepared by conditions.

Final Thoughts

One thing I’ve learned while planning my own Colorado Trail journey is that most of these mistakes aren’t caused by a lack of experience. They’re caused by a lack of planning.

The good news is that you don’t need to have everything figured out before you start. You don’t need the perfect gear setup. You don’t need years of backpacking experience. And you certainly don’t need to quit your job and disappear into the mountains for a month.

You just need a plan.

That’s especially true for section hikers. Most of us are trying to fit the Colorado Trail around work schedules, family commitments, budgets, travel logistics, and limited vacation time. We don’t have the luxury of simply showing up and figuring it out as we go. Every trip window matters.

That’s one of the reasons I started putting together my own planning documents and spreadsheets. The more I researched the trail, the more I realized that breaking it into manageable sections made the entire goal feel achievable.

Instead of thinking, “How am I ever going to hike 486 miles?”, I started thinking: “How do I hike the next section?”

That simple shift completely changed how I looked at the Colorado Trail.

If you’re planning your own Colorado Trail adventure, I hope this article helps you avoid some of the mistakes I’ve seen come up again and again. A little planning today can save a lot of frustration on the trail tomorrow.
