Continental Divide Trail
The Continental Divide Trail (CDT) runs from the Mexican border in New Mexico to the Canadian border in Montana, weaving through the Rocky Mountains in Colorado, Wyoming, and Idaho. Many of us consider it the most remote and challenging of America’s “Big Three” trails—offering solitude and stunning scenery. Our Popular Trails page includes comparisons with the PCT, AT, and other major hikes.

1. Route & Alternates
The CDT is known for multiple “official” routes and “alternates,” granting flexibility in how we trek. Some sections in Montana/Idaho allow different paths along the divide. Though the official distance is often listed at about 3,100 miles, your personal mileage might differ by hundreds of miles, depending on the paths you choose.
2. Navigation Challenges
Unlike the AT or PCT, the CDT can have fewer signs, and the trail may be faint in spots. We like to carry reliable GPS apps or detailed maps. Snowfields, blowdowns, and reroutes can obscure the path, making solid navigation skills essential. Hiker Resources offers info on planning and navigating remote terrain.
3. Permits & Land Agencies
There’s no single CDT permit. As we hike, we cross lands managed by national parks (Glacier, Yellowstone), national forests, and the BLM, each with distinct regulations (bear canisters, camping permits, fire bans, etc.). We research each jurisdiction in advance. Hiker Resources and official websites outline more on permit details.
4. High Altitude & Snow Considerations
Much of the CDT sits above 10,000 feet, especially in Colorado. Early-season snow can linger, and many of us carry microspikes or an ice axe if starting early or anticipating a heavy snowpack. Storms roll in quickly at high elevation, so we monitor forecasts and remain flexible.
5. Resupply & Towns
The CDT is more remote than the AT/PCT, but there are enough towns for resupply. Popular stops: Lordsburg, Grants, Chama, Pagosa Springs, Silverthorne, Steamboat Springs, Rawlins, Lander, Dubois, West Yellowstone, Helena, and East Glacier. The Hiker Resources page has deeper info on food logistics.
6. Wildlife & Safety
Grizzlies roam parts of Montana and Wyoming/Idaho, in addition to black bears, moose, elk, and mountain lions. We often carry bear spray in grizzly country and practice safe food storage methods. High-elevation thunderstorms can be fierce—if lightning looms, we descend from exposed ridges.
7. Recommended Gear & Seasonal
While ultralight setups are common, it’s important to bring enough insulation for cold mornings in the Rockies. A sturdy shelter for high winds, extra layers, and possibly traction devices (in Glacier or the San Juans) are often part of the kit. Bear canisters or Ursacks are recommended in grizzly zones. Northbound hikers typically start in April–May, with southbound departures in June–July. Gear Lists provides ideas for handling long distances and variable conditions.
8. Conclusion & Disclaimer
Many of us feel the CDT offers a wilderness experience unparalleled among the Big Three. With diligent planning, sound navigation, and an open mind, it can be a once-in-a- lifetime journey. For the latest details, the Continental Divide Trail Coalition remains a prime resource. For a broader look at extended treks, the Hiker Resources section also covers planning insights.
We aren’t officially tied to the CDTC, and conditions can change rapidly. We prefer verifying details with local ranger districts or official sources before heading out.
