The Colorado Trail is a ~500 route that goes from just outside Denver, Colorado across the state to Durango. No permits are necessary and there are many places along the way to resupply, typically every 3-5 days.
There is a fairly short window of time to hike the whole trail as snow often presents a serious challenge well into June and some years well into July, then come September early season snowstorms are not uncommon.
The biggest challenges for a hike like this are: the altitude (tough breathing), afternoon electrical storms (especially above tree line), wildfire closures (currently the last 70 miles are closed), and figuring out how to get home!
