There is plenty of affordable lodging in Durango on the North side of the river crossing. Knights Inn is about $80 a night. As long as you stay away from the Doubletree ($200 a night) Spanish Trails ($70,) Knights Inn ($80) you should be okay. Keep in mind that you may have some hiking buddies at that point and you might share a room. The only thing that may be an issue is that the “Bus station” is 3 miles south of the Knights Inn. Which, if you just got done walking 500 miles, another 3 miles is nothing big. I’m not sure what time the trolley starts running though. The “Bus station” or the bus loading lot is located at 250 W 8th St (per the operator at Greyhound) Personally, I believe at the end of my own hike, I am going to rent a car and drive back home to Dallas. Im starting at the end of June, July (depending on snowpack.)
