Critical Planning: Before You Hit the Trail in Colorado
Preparation is not just recommended in Colorado; it’s mandatory for a safe and enjoyable trip. The Rocky Mountains demand respect. Before you even think about lacing up your boots, you need to understand the unique challenges of high-altitude environments.
High-Altitude Acclimatization: Your #1 Priority
The single most important factor for a successful trip is acclimatization. Acute Mountain Sickness (AMS) is a real and dangerous condition that can affect anyone, regardless of fitness level. Symptoms range from a persistent headache and nausea to more severe, life-threatening conditions. Your #1 priority is to give your body time to adjust.
- Spend at least one, preferably two, nights in a high-altitude city like Denver (5,280 ft) or a mountain town like Leadville or Breckenridge (9,000-10,000 ft) before starting your backpacking trip.
- Hydrate relentlessly. Drink more water than you think you need and avoid alcohol for the first few days.
- Consider an “acclimatization hike” on a less strenuous trail before your main event. While tackling the highest hike in Colorado, the 14,433-foot summit of Mt. Elbert, is an incredible goal, it should be attempted after you are fully acclimatized, not as a warm-up.
Permits, Regulations, and Leave No Trace
Navigating Colorado’s permit system is a key part of the planning process. Some of the most popular areas, like the Maroon Bells-Snowmass Wilderness (for the Four Pass Loop) and Rocky Mountain National Park, require highly competitive permits that must be booked months in advance on Recreation.gov. Other areas, primarily in National Forests, simply require you to fill out a free self-registration tag at the trailhead. Always check the specific regulations for the area you plan to visit.
More importantly, every visitor must practice the 7 Leave No Trace (LNT) principles. This means packing out everything you pack in (including food scraps), disposing of human waste properly (using catholes or pack-out systems), and respecting wildlife and other visitors.
Wildlife Safety: Bears, Moose, and More
You are a visitor in the home of Colorado’s incredible wildlife. The most common question we hear is, “Do I need bear spray when hiking in Colorado?” The short answer is a definitive yes. It is a highly recommended safety tool, not just for the unlikely event of a defensive black bear encounter, but also for other animals like mountain lions or an aggressive moose. Keep it accessible on your pack’s hip belt or shoulder strap, not buried inside.
Proper food storage is non-negotiable. Many popular areas now require approved bear canisters. In other areas, you must know how to properly execute a PCT-style bear hang to keep your food (and all scented items) safe. Remember, moose can be more dangerous and unpredictable than bears; give them an extremely wide berth and never get between a mother and her calf.
The Top 4 Multi-Day Backpacking Trips in Colorado
Now for the fun part! Here are four of the absolute best multi-day backpacking trips in the state, offering a range of challenges, scenery, and experiences.
-
The Four Pass Loop (Maroon Bells-Snowmass Wilderness)
Why It’s a Classic:
This is it. The crown jewel. Many consider this the single most scenic hike in Colorado, and for good reason. The 28-mile loop traverses four stunning mountain passes over 12,000 feet, offering jaw-dropping views of the iconic Maroon Bells, turquoise alpine lakes, and wildflower-filled basins. It’s a strenuous but incredibly rewarding journey that belongs on every backpacker’s bucket list.
Trail Details:
Distance 28 miles Elevation Gain ~8,000 feet Typical Duration 3-4 Days Difficulty Strenuous Logistics & Permits:
This is the trip’s biggest hurdle. You need an overnight permit for the Core Enchantments Zone, which is released on a specific date in February on Recreation.gov and sells out in minutes. You also need to book a shuttle bus from Aspen to the trailhead. Plan for your 2025 trip now!
Route Overview:
Most hikers travel counter-clockwise from Maroon Lake, tackling Buckskin Pass on day one, followed by Trail Rider, Frigid Air, and West Maroon Pass on subsequent days. Each pass presents a grueling climb and a spectacular reward.
-
The Zirkel Circle (Mount Zirkel Wilderness)
Why You Should Go:
Looking for a less-crowded alternative with a huge scenic payoff? Head north to the Mount Zirkel Wilderness near Steamboat Springs. This loop offers incredible solitude, lush meadows bursting with wildflowers in July, and a more manageable distance, making it one of the best 2 day backpacking trips Colorado has to offer for those short on time.
Trail Details:
Distance ~11 miles Elevation Gain ~2,500 feet Typical Duration 2 Days Difficulty Moderate Logistics & Permits:
Logistics are a breeze. The trailhead is an easy drive from Steamboat Springs, and permits are free and self-issued at the trailhead kiosk. It’s a perfect trip for a more spontaneous weekend.
Route Overview:
The loop connects the Gilpin Lake Trail and Gold Creek Lake Trail. A great 2-day plan is to hike up to Gilpin Lake on day one to camp, then hike over the scenic saddle and down past Gold Creek Lake on day two.
-
Lost Creek Wilderness Loop
Why You Should Go:
This trip is all about unique geology. Instead of soaring peaks, you’ll wander through a maze of incredible granite domes, natural arches, and towering rock formations. Its relatively lower elevation makes it accessible earlier in the spring and later in the fall than other high-country trips.
Trail Details:
Distance ~28 miles Elevation Gain ~4,500 feet Typical Duration 2-3 Days Difficulty Moderate Logistics & Permits:
Located just over an hour from Denver, this is one of the most accessible multi-day trips for Front Range residents. No permits are required, just a simple self-registration at the trailhead.
Route Overview:
The loop can be started from several trailheads. It follows sections of the Brookside-McCurdy and Goose Creek trails. Water can be scarce in certain sections, so be sure to check recent trail reports and plan your water carries accordingly.
-
Chicago Basin (San Juan Mountains)
Why You Should Go:
For the aspiring mountaineer, there is no better destination. Tucked deep in the rugged San Juan Mountains, Chicago Basin serves as a basecamp for summiting three of Colorado’s most remote 14ers: Mount Eolus, Windom Peak, and Sunlight Peak. The adventure begins with a ride on the historic Durango & Silverton Narrow Gauge Railroad, which drops you off in the middle of the wilderness.
Trail Details:
Distance 14 miles (approach) + peaks Elevation Gain ~3,000 ft (to basecamp) Typical Duration 3-4 Days Difficulty Strenuous Logistics & Permits:
While no hiking permit is needed, you must book a round-trip ticket on the train to the Needleton stop, which serves as the trailhead. This is the only practical way to access the basin. Book your train tickets well in advance.
Route Overview:
The train drops you off by the Animas River. From there, it’s a 7-mile hike into the basin where you’ll set up a multi-night basecamp. Subsequent days are spent on challenging day hikes to summit the surrounding 14,000-foot peaks before hiking out to catch your return train.

- Start Early, Finish Early: Aim to be up and over any high mountain passes before noon. Afternoon thunderstorms are a serious electrical hazard above the treeline.

- Filter All Water: Giardia and other waterborne pathogens are common in backcountry water sources. Never drink directly from a stream or lake, no matter how pristine it appears.
- Check Wildfire Conditions: Before you leave, check official sources like inciweb.nwcg.gov for active fires. Be prepared for smoky conditions or last-minute trail closures during fire season.
- Leave Your Itinerary: Always tell a reliable friend or family member your exact route, your planned campsites, and your expected return time.
