The Colorado Trail is a 486-mile long-distance trail in Colorado, running from Waterton Canyon near Denver to Durango. It is known for its spectacular scenery and challenging high-altitude terrain, with most of the trail being above 10,000 feet. It is popular for hiking, backpacking, and horseback riding, and approximately 75% of the trail is also open to mountain biking. Managed by the Colorado Trail Foundation (CTF), the trail is divided into segments, with thru-hikers typically completing it in 4–6 weeks, though day hikes are also popular.

- Potential Challenges: Be prepared for challenging weather, including afternoon thunderstorms, and be aware of high-altitude risks like hypothermia and dehydration.
- Resupply: The CTF provides detailed information in their guidebook and on their website for resupply points and planning your trip.
- Safety: Be prepared for lightning, especially in the high country. Avoid higher elevations and ridges during afternoon storms.
