Trans-America Trail West Section
America's ultimate cross-country adventure
The Trans-America Trail’s western section picks up where the Great Plains end and the real adventure begins, threading 2,500 miles of dirt, gravel, and two-track from Colorado’s high country to the Pacific Ocean. This isn’t just a trail — it’s a carefully researched anthology of America’s best backroads, linking ghost towns, mining districts, and forgotten highways through the Rockies, Great Basin, and Mojave Desert. The route tackles legendary passes like Imogene and Engineer in Colorado, skirts the edge of Death Valley, and finishes with a triumphant roll through California’s Central Valley to the coast.
Moderate difficulty overall but with expert sections that’ll humble cocky drivers, especially in Colorado’s alpine zones above treeline. Any high-clearance vehicle can handle most of it, though 4WD is essential for the technical bits. Best run west to east in late spring through early fall, avoiding winter snow in the mountains. GPS tracks are available through the TAT organization, and the route is designed for self-supported travel with regular resupply opportunities. This is overlanding at its finest — a month-long journey that captures the essence of American adventure travel and connects you to the country’s pioneering spirit.

Frequently asked questions
Can a stock 4Runner or Wrangler run the TAT West without modifications?
A stock high-clearance vehicle can complete most of it, but you'll want decent all-terrain tires and solid recovery gear — some segments in Colorado and Utah will punish street tires and low clearance. Lift and skid plates help but aren't mandatory.
When does the TAT West Section actually open and close for the season?
May through October is the reliable window, but high-altitude segments in Colorado near 12,800 ft can stay snowed in well into June and get hit early in October. Check current conditions on specific passes before committing to a start date.
Do you need permits to run the TAT West, and are there fees?
No single permit covers the whole route — it crosses land managed by multiple federal, state, and county agencies. Some segments pass through areas with day-use or camping fees; National Forest and BLM areas are generally free for dispersed camping, but carry cash for the occasional fee area.
What's the hardest section of the TAT West and what should I expect?
The Colorado Rockies segment is the most demanding — steep shelf roads, loose rock, and elevations pushing 12,800 ft that will stress cooling systems and driver confidence. It's rated moderate overall, but that section rewards experience and penalizes unpreparedness.
How should I plan water and fuel on a 2,500-mile route through remote desert and mountains?
Carry at minimum 5 gallons of water on board at all times — stretches through Utah and Nevada have long gaps between reliable sources and water crossings aren't always potable. For fuel, research your tank range carefully; some remote segments have 100+ miles between gas stations, and those stations don't always keep posted hours.
