Trans-America Trail – Colorado Section
Colorado's high-altitude spine across mining country
At 12,800 feet on Ophir Pass, the Trans-America Trail’s Colorado section reminds you that this state doesn’t mess around. The 400-mile stretch from Cortez to the Kansas border cuts straight through the San Juan Mountains, across the Continental Divide, and down through mining country that’s been chewing up vehicles for over a century. This isn’t just another scenic route—it’s America’s backbone trail, the coast-to-coast overland route that started as Sam Correro’s vision to connect rural America on dirt.
Your high-clearance 4WD will earn its keep on this seven-to-ten-day crossing. The trail climbs 15,000 feet of elevation gain through alpine passes, ghost towns, and mining districts where Model T Fords once hauled ore. Engineer Pass and Cinnamon Pass test your line choice with loose rock and exposure, while water crossings in the San Juans can turn violent during snowmelt season. Cell service disappears for days at a time, making this genuinely remote travel. Stock rigs handle most sections fine, but the high-altitude passes demand respect—engine power drops, weather changes fast, and recovery points are scarce above treeline.
July through September offers the only reliable window when snow clears the high passes. Earlier means postholing through drifts; later risks early storms that can strand you until spring. Dispersed camping opportunities are endless once you clear the National Forest restrictions around popular areas. Fuel intervals stretch long between Cortez and the eastern plains, so carry extra. The trail threads through multiple land management agencies without permits required, but respect private property markers and mining claims—this country still works for a living.
What you get is the real Colorado—not the tourist version. Mining ruins that tell stories of boom and bust. Elk watching you from ridgelines at dawn. Nights so quiet and dark you remember what silence sounds like. The Trans-America Trail’s Colorado section strips away everything except what matters: your rig, the road ahead, and country that hasn’t been sanitized for mass consumption. It’s overland travel the way it was meant to be—challenging, remote, and honest about what it demands from both driver and machine.
Q: What vehicle do I need for the Trans-America Trail Colorado section?
A high-clearance 4WD is the minimum requirement, with stock rigs handling most sections fine, though the high-altitude passes and rocky sections will test your undercarriage and line choice.
Q: How long does the Colorado section take?
Most overlanders complete the 400-mile Colorado section in seven to ten days, depending on weather, trail conditions, and how much time you spend exploring mining ruins and side trails.
Q: When is the best time to run the Colorado TAT?
July through September is the only reliable window when snow clears the high passes, with August being optimal for weather and trail conditions.
Q: Do I need permits for the Trans-America Trail in Colorado?
No permits are required as the trail crosses multiple public land agencies, but respect private property markers and active mining claims throughout the route.
Q: How remote is the Colorado section?
Cell service disappears for days at a time, fuel intervals stretch long between towns, and recovery points are scarce above treeline, making this genuinely remote overland travel.
Q: What’s the highest elevation on Colorado’s Trans-America Trail?
The trail reaches 12,800 feet on Ophir Pass, crossing the Continental Divide and several other high-altitude passes through the San Juan Mountains.

Frequently asked questions
Can a stock Tacoma or 4Runner handle the Colorado TAT section?
A stock high-clearance 4WD will get through most of it, but you'll want decent all-terrain tires and working low-range — some passes and rocky two-tracks will punish street tires and open differentials. Lift isn't required, but skid plates are strongly advised given the rocky mining-road terrain.
When does the Colorado TAT section actually open and close?
July through September is the reliable window — high passes near 12,800 feet hold snow well into June and can get hit again by late September. Attempting outside that window risks impassable snowpack or mud on the high routes with no bailout nearby.
Do you need permits to run the Colorado TAT section?
No single permit covers the whole route — it crosses BLM, USFS, and some private land managed under existing access agreements. No fee is required to drive it, but check current MVUM maps for any seasonal closures on specific Forest Service segments before you go.
What's the hardest section on the Colorado TAT and what should I expect?
The high-altitude passes through the San Juan Mountains are the crux — loose rock, narrow shelf roads, and exposed ridgelines above treeline where weather moves in fast. None of it is technically extreme, but the combination of altitude, remoteness, and rapidly changing conditions is where people get into trouble.
How far apart are fuel stops on the Colorado TAT, and what range do I need?
Plan for at least 100-mile fuel range between reliable stops — some stretches through remote southwest Colorado have very limited services, and small-town stations can be closed or out of fuel. Carry a dedicated jerry can; running dry out here is a long, expensive problem.
