Colorado Trail Thru-Hike: Route, Itinerary & Complete Guide
The Colorado Trail crosses the Rocky Mountains from Waterton Canyon southwest of Denver to Junction Creek near Durango. A thru-hike is roughly 485–492 miles depending on whether you choose Collegiate East or Collegiate West, climbs about 89,000 feet in total, averages more than 10,300 feet above sea level and normally takes four to six weeks.
How Long Is the Colorado Trail?
The Colorado Trail system contains 567 maintained trail miles, but an end-to-end thru-hiker does not walk all 567. The 567-mile figure includes both alternative routes through the Collegiate Peaks. A Denver-to-Durango thru-hike is roughly 485–486 miles via Collegiate East or about 491–492 miles via Collegiate West. The Colorado Trail Foundation says a typical thru-hike takes four to six weeks.
The original Denver–Durango trail is roughly 485 miles. In 2012, about 80 miles of Continental Divide Trail on the west side of the Collegiate Peaks were added as Collegiate West. Because the Foundation maintains both East and West, the complete CT trail system totals 567 miles. A thru-hiker chooses one branch rather than walking both.
Colorado Trail Route Map.
The route leaves the Denver foothills, crosses South Park, climbs into the Tenmile and Sawatch ranges, divides around the Collegiate Peaks, then traverses increasingly remote high country before reaching the San Juan Mountains and descending into Durango.
What Is the Colorado Trail Actually Like?
The Foundation divides the CT system into 33 segments, including the five Collegiate West segments. The character shifts repeatedly as elevation, vegetation, town access and exposure change.
Learn the Trail
The lower-elevation opening gives southbound hikers time to settle equipment and pacing before entering sustained alpine terrain. Water planning already matters around Buffalo Creek.
Enter the Rockies
South Park gives way to the Tenmile Range, ski-country trail towns and the first sustained stretches above treeline.
High Sawatch
The route passes through or near major Colorado mountain country, including the Mount Massive and Mount Elbert corridor.
Choose a Collegiate
Collegiate East stays lower and closer to towns. Collegiate West climbs higher onto the Continental Divide and adds more exposure.
Longer, Quieter Miles
Sargents Mesa, Cochetopa country and the approach toward the San Juans reward disciplined water and food planning.
The San Juan Finish
High ridges, long exposure and extraordinary scenery make the final third one of the CT’s greatest sections—and one of the least forgiving in storms.
The Colorado Trail Does Not Begin in the High Rockies.
Waterton Canyon and the South Platte country provide a lower and often hotter introduction. That makes southbound travel useful for adaptation—but it also means hikers should not assume Colorado mountain hiking automatically means abundant water and cool temperatures.

They answer different questions. The larger number describes the entire maintained trail network. The smaller number describes an actual Denver-to-Durango journey using one of the two Collegiate routes.
| Number | What it describes | Should a thru-hiker plan this mileage? |
|---|---|---|
| 567 miles | Entire Colorado Trail system, including BOTH Collegiate East and Collegiate West | No. You normally choose one Collegiate route. |
| ≈485–486 miles | Traditional Denver–Durango thru-hike using Collegiate East | Yes, approximately. |
| ≈491–492 miles | Denver–Durango thru-hike using the slightly longer Collegiate West | Yes, approximately. |
| 160 miles | Collegiate Loop combining East and West as a standalone circuit | Only if hiking the Collegiate Loop rather than continuing to Durango. |
Collegiate East vs Collegiate West.
The branches split near Twin Lakes and reunite south of Monarch Pass. Neither is merely a detour. They create meaningfully different thru-hikes.
| Factor | Collegiate East | Collegiate West |
|---|---|---|
| Branch distance | 78.3 miles | 84.8 miles |
| Elevation gain | ≈17,800 ft | ≈19,800 ft |
| Terrain | Generally lower and more wooded | Higher, more alpine and more exposed |
| Snow melt | Usually earlier | Often among the last CT miles to melt out |
| Town access | Generally easier | More remote overall |
| Highlights | Harvard Lakes, Princeton area, Chalk Cliffs | Hope Pass, Lake Ann, Alpine Tunnel, Continental Divide |
| Best fit | Earlier season, simpler logistics, first CT | Experienced hikers seeking maximum alpine terrain |
Collegiate West is not automatically “better.”
It is higher, more exposed and spectacularly alpine, but those same characteristics mean more lightning exposure, greater snow sensitivity and less protection in poor weather. East can be the stronger choice when the snow year, start date or hiking experience argues for it.
The CT Runs Through Colorado’s Highest Mountain Country.
Near Leadville and Twin Lakes, the trail passes beneath Mount Massive and Mount Elbert before reaching the Collegiate split. The CT itself does not summit those fourteeners, but short or substantial side trips can turn a thru-hike into a completely different objective.

The Colorado Trail Foundation recommends allowing four to six weeks for an end-to-end hike. Your sustainable daily average matters more than your biggest day.
| Schedule | Approx. average | Style | Who it fits |
|---|---|---|---|
| 28 days | ≈17–18 mi/day | Fast thru-hike | Experienced long-distance hikers with efficient systems and minimal town time. |
| 32–35 days | ≈14–15 mi/day | Balanced | A strong target for fit thru-hikers who want some town and weather margin. |
| 38–42 days | ≈11.5–13 mi/day | Conservative | First thru-hikes, heavier packs or itineraries with more rest and side trips. |
| 6+ weeks | Flexible | Slow travel | Section-style pacing, peak side trips, photography and larger weather buffers. |
Do not calculate every day from 485 ÷ number of days.
The CT is too uneven for that. Town days, resupply access, lightning timing, water carries and high alpine sections will create short days and long days. Build around a sustainable weekly average rather than forcing the same mileage through every terrain type.
Southbound vs Northbound on the Colorado Trail.
Both directions are legitimate, but they create different acclimatization and transportation problems.
The Natural Progression
Start lower, gradually move toward higher country and reach the San Juan Mountains after several weeks of hiking. This is the most intuitive altitude and fitness progression.
High Country First
Begin with serious San Juan terrain immediately. Northbound can work well for experienced, acclimatized hikers or for transportation and seasonal reasons.
Transportation Matters
For a one-way trip, the Foundation suggests considering leaving your vehicle near the finish and arranging transportation to the start while your timing is still predictable.
By the Time You Reach the Sawatch, the Trail Has Changed.
Altitude, longer alpine sections and repeated climbing begin to dominate the journey. The lower-elevation opening miles are behind you, but the largest sustained high-country sections are still ahead.

The CT passes near a useful chain of mountain towns. Some are essentially on the trail; others require a hitch, shuttle or longer side trip.
| Area | Useful town / service | Role in a thru-hike | Planning note |
|---|---|---|---|
| Front Range | Bailey / Jefferson | Early food or logistics | Useful if the opening carry was deliberately light. |
| Tenmile | Breckenridge / Frisco | Major resupply | Full-service towns and natural first major reset. |
| Sawatch | Leadville | Major resupply / zero | Excellent access to lodging, food and gear around the high central trail. |
| Collegiate split | Twin Lakes / Buena Vista | Food + branch decision | Useful place to reassess snow and weather before choosing East or West. |
| Monarch area | Salida | Major resupply / zero | Strong full-service option around the midpoint. |
| Southern middle | Creede / Lake City | San Juan staging resupply | Town access can require substantial travel off the trail. |
| San Juans | Silverton | Late resupply / recovery | Useful before the final miles toward Durango depending on route and schedule. |
| Western terminus | Durango | Finish logistics | Full-service city for lodging, transport and post-trail travel. |
Colorado Trail resupply is a town-access problem more than a food-availability problem.
Do not mail every box months in advance. Determine which towns you actually want to visit, which trail crossings make access reasonable and where dietary requirements justify a shipment. Flexible buying works well for many hikers.
How Much Water Do You Need on the Colorado Trail?
Water is abundant across much of the trail, but the Foundation specifically warns hikers not to assume every mapped seasonal source will be flowing.
A potentially long dry stretch in the Buffalo Creek area.
Cochetopa-area sources can dry unusually early.
Potentially the longest major dry stretch identified by the Foundation.
A collapsible reserve adds little weight when empty and solves dry-year carries.
The Colorado Trail Foundation has specifically warned that 2026’s low snowpack and high temperatures may cause seasonal sources to disappear unusually early. Buffalo Creek, Sargents Mesa and some high sections are among the areas where hikers should be especially conservative.
High Trail Means Lightning Is a Daily Scheduling Problem.
Many Colorado Trail miles stay exposed above treeline long enough that the day’s departure time matters as much as the day’s mileage. Summer thunderstorms often build in the afternoon. On ridge-and-pass days, the safe itinerary is built backward from when you want to be below exposed terrain.
Photo source: Wikimedia CommonsDo You Need a Permit to Hike the Colorado Trail?
One of the CT’s advantages is that it does not have the single high-demand thru-hike permit bottleneck seen on trails such as the John Muir Trail.
No Single Thru-Hike Permit
You do not apply for one Colorado Trail permit covering Denver to Durango.
Free Self-Service Permits
Where the CT enters wilderness, the Forest Service uses free self-service registration. Follow the instructions at the permit station.
Clear Creek SWA
Simply hiking through the short State Wildlife Area section no longer requires the former pass. Camping, fishing or hunting there can still trigger CPW requirements.
No Camping
The eastern terminus corridor is one of the places where dispersed camping is not allowed. Plan the first legal camp beyond it.
Stay on the Trail
The CT crosses or approaches private property in some areas. Use the official guide and existing camps rather than assuming every flat area is public.
Check Current Rules
Wildfire conditions can change restrictions during the season. Local Forest Service orders override old guidebook advice.
Best Time to Hike the Colorado Trail.
The Colorado Trail Foundation identifies July, August and September as the primary season for long-distance travel.
| Period | Snow | Weather | Water | Planning position |
|---|---|---|---|---|
| June | High passes may retain substantial snow | Cooler | Generally stronger | Early and condition-dependent |
| Early July | Usually improving | Long daylight | Generally good | CTF’s normal earliest thru-hike target |
| Late July | Usually manageable | Monsoon storms increase | Good to variable | Prime season |
| August | Usually minimal | Frequent afternoon storm potential | Seasonal sources decline | Prime season |
| Early September | Normally clear | Colder nights | Lowest seasonal sources | Excellent late-season option |
| Late September | New snow becomes possible | Shorter days, cold nights | Low | CTF recommends finishing by Sept. 30 |
| October | Longer-lasting storms increasingly likely | Cold and unstable | Services closing | Not normal thru-hiking season |
Collegiate West often controls an early-season itinerary.
The Foundation notes that Collegiate West historically melts later than much of the rest of the CT. A Denver start that works perfectly for Collegiate East may still reach West before its highest terrain is in normal summer condition.
How Hard Is a Colorado Trail Thru-Hike?
The trail normally remains hiking terrain rather than technical mountaineering terrain, but its average elevation and repeated climbing make it a serious endurance objective.
10,300-ft Average
The CT does not merely touch altitude at one summit. Hikers repeatedly sleep, climb and recover at elevations that slow sea-level performance.
≈89,000 ft of Gain
Endurance depends on efficiently repeating climbs rather than surviving one enormous ascent.
Lightning Exposure
High ridges make afternoon thunderstorm timing one of the trail’s recurring objective hazards.
4–6 Weeks
Foot care, nutrition, sleep and recovery become as important as cardiovascular fitness.
Season Dependent
An early start can turn normal trail hiking into snow travel, especially on high north-facing slopes and Collegiate West.
Variable
Some sections pass close to ski towns and highways; others cross long mountain stretches where assistance can take hours.
Southbound Hikers Save Some of the Best—and Highest—Terrain for Last.
The southern Colorado mountains reward weeks of accumulated trail fitness, but they also demand judgment. Long exposed sections, scarce cell service and fast-changing storms mean the strongest legs on the trail still need conservative weather decisions.
Photo source: Wikimedia Commons · Weminuche WildernessColorado Trail Gear Priorities.
The best CT kit is not simply the lightest kit. It must protect you through cold nights, thunderstorms, hail, strong sun and occasional long dry carries.
Storm-Worthy
Colorado storms can combine wind, heavy rain and hail. Your shelter should remain functional above treeline when the timing does not go perfectly.
Real Waterproof Layer
Afternoon thunderstorms are too regular to treat rain protection as an emergency-only item.
Freezing-Night Margin
Summer does not prevent freezing temperatures at high camps, especially late in the season.
Expandable Capacity
Carry enough maximum capacity for the longest dry section without hauling unnecessary water through wetter areas.
Current Offline Mapping
The CT is rerouted over time. Carry current mapping plus an independent backup rather than an old GPX file alone.
Satellite Layer
The Foundation warns that cell coverage is spotty. A satellite messenger provides a more realistic emergency-communication layer.
How Much Does the Colorado Trail Cost?
There is no official CT thru-hike price because transportation, gear ownership, town frequency and lodging choices vary enormously. The useful approach is to budget by category.
There is no trail-wide thru-hike permit purchase.
Backcountry food plus higher-priced meals and snacks in mountain towns.
Hotels, restaurants, laundry and zero days can become the largest on-trail expense.
Denver access is relatively simple; the one-way Durango connection needs its own plan.
Budget town behavior, not just backpacking food.
Two hikers carrying identical equipment can finish with radically different expenses if one sleeps outdoors and resupplies quickly while the other takes hotel zeros in Breckenridge, Leadville, Salida and Silverton. Decide your town style before setting the budget.
September Trades Thunderstorm Season for Cold Nights and a Shorter Clock.
Early autumn can be one of the most beautiful periods on the trail, especially in the San Juans. The trade is obvious: daylight contracts, overnight temperatures fall and the first substantial snowstorm becomes increasingly possible.
Photo: Leaflet · Wikimedia Commons · public domainWaterton Canyon and Durango Logistics.
The CT is easier to reach than many American long trails, but the two trailheads are hundreds of driving miles apart. Solve the one-way transportation before departure.
Waterton Canyon
The CT begins southwest of the Denver metropolitan area. There is no overnight parking at Waterton Canyon itself.
Junction Creek
The western end lies immediately outside Durango, making post-hike lodging, food and onward transportation comparatively simple.
Leave the Car at the Finish
CTF suggests that one-way travelers consider positioning the car near the endpoint and arranging transport to the start while the start date remains predictable.
Colorado Trail Hiking Route vs Mountain-Bike Route.
The CT is famous in both thru-hiking and bikepacking communities, but bicycles cannot legally enter designated wilderness areas.
Stay on the Foot Trail.
Hikers can travel the wilderness sections that form part of the official walking route, including portions cyclists must bypass.
The Foundation’s current guide system identifies the complete pedestrian trail separately from mandatory bicycle detours.
Expect Wilderness Detours.
Colorado Trail Foundation’s current Databook describes a roughly 540-mile cycling route using five mandatory wilderness detours.
Do not transfer a hiker’s mileages, resupply assumptions or GPX directly to a mountain-bike itinerary.

Use Current Colorado Trail Information.
Reroutes, fires, water and snow can change after any guide is published. The Colorado Trail Foundation explicitly recommends using current alerts alongside its latest guidebooks and maps.
Colorado Trail Thru-Hike FAQ.
The questions that create the most confusion when planning an end-to-end Colorado Trail hike.
How long is the Colorado Trail?
The complete Colorado Trail system contains 567 miles because it includes both Collegiate East and Collegiate West. An actual Denver-to-Durango thru-hike is roughly 485–486 miles using Collegiate East or approximately 491–492 miles using Collegiate West.
Why do some sources say the Colorado Trail is 567 miles?
The Colorado Trail Foundation maintains both Collegiate East and Collegiate West. Counting both branches produces the 567-mile total. End-to-end hikers normally choose one branch rather than hiking both.
How long does it take to thru-hike the Colorado Trail?
The Colorado Trail Foundation says a typical thru-hike takes four to six weeks. A four-week hike requires a much higher sustainable daily mileage than a five- or six-week itinerary.
Where does the Colorado Trail start and end?
The eastern terminus is at Waterton Canyon southwest of Denver. The western terminus is at Junction Creek near Durango.
What is the highest point on the Colorado Trail?
The Colorado Trail Foundation lists the trail’s highest elevation as 13,271 feet near Coney Summit in Segment 22.
What is the average elevation of the Colorado Trail?
The Colorado Trail Foundation lists the average elevation at more than 10,300 feet.
How much elevation gain is on the Colorado Trail?
The Colorado Trail Foundation lists approximately 89,000 feet of total elevation gain across the trail system.
Do you need a permit to thru-hike the Colorado Trail?
There is no single trail-wide Colorado Trail permit. Free self-service permits apply when entering wilderness areas. Additional local requirements can apply for activities such as camping, fishing or hunting in specific managed areas.
Which is better: Collegiate East or Collegiate West?
They provide different trips. Collegiate East is 78.3 miles with roughly 17,800 feet of gain and generally lower terrain. Collegiate West is 84.8 miles with roughly 19,800 feet of gain and more high, exposed alpine travel. Snowpack, weather, experience and desired scenery should determine the choice.
What is the Collegiate Loop?
The Collegiate Loop combines Collegiate East and Collegiate West into an approximately 160-mile standalone circuit between Twin Lakes and the area south of Monarch Pass.
What is the best time to hike the Colorado Trail?
July through September is the normal distance-hiking season. The Colorado Trail Foundation generally recommends starting no earlier than July 1 and finishing no later than September 30, while recognizing that snow conditions vary by year.
Should you hike the Colorado Trail southbound or northbound?
Both are possible. Southbound from Denver gives hikers a gradual progression from lower terrain into higher Sawatch and San Juan country. Northbound begins with high San Juan terrain immediately.
Where can you resupply on the Colorado Trail?
Common resupply areas include Bailey or Jefferson, Breckenridge or Frisco, Leadville, Twin Lakes or Buena Vista, Salida, Creede or Lake City, Silverton and Durango. Access distance varies significantly.
What are the longest dry sections on the Colorado Trail?
The Colorado Trail Foundation identifies potential dry stretches of roughly 14 miles around Segments 2–3, about 11 miles in Segments 18–19 and up to roughly 22 miles in Segments 26–27 under dry conditions.
Is the Colorado Trail technical?
The normal summer hiking route is a backpacking trail rather than a technical climbing route. Snow, severe weather or off-season conditions can substantially increase the skills and equipment required.
Can you mountain bike the entire Colorado Trail?
Not on the exact hiking route because bicycles are prohibited in designated wilderness areas. Colorado Trail Foundation resources describe mandatory bicycle detours that create a separate cycling route of roughly 540 miles.
Is the Colorado Trail good for a first thru-hike?
For a backpacker with solid multi-day experience, the CT can be an excellent first long thru-hike because it is shorter than the Triple Crown trails and has useful trail-town access. Its high average elevation, thunderstorms, long climbs and multi-week duration still demand serious preparation.
Does the Colorado Trail overlap the Continental Divide Trail?
Yes. Significant portions of the Colorado Trail share the Continental Divide National Scenic Trail, especially through high central and southern Colorado. The two are still separate long-distance trails with very different overall lengths and endpoints.
Choose the Collegiate Route, Then Build the Trip Around Altitude, Water and Weather.
The Colorado Trail is approachable because it does not require a competitive trail-wide permit and passes near useful mountain towns. It is demanding because almost 500 miles of walking happen at unusually high elevation, with roughly 89,000 feet of climbing and repeated exposure to Colorado’s afternoon storms. Solve the route choice, water capacity and realistic daily pace before optimizing ounces.
