For a different kind of experience, you could pitch a tent for one nite at each of the 5 tri state points where Colorado meets up with 2 other states. You could also camp at the four corners point, but heck...nobody does that anymore, it's too popular. (
Additionally, the 4 corners marker is inaccurrately located! )
#1: Colorado-Nebraska-Kansas
#2: Colorado-Kansas-Oklahoma
#3: Colorado-Oklahoma-New Mexico
#4: Colorado-Utah-Wyoming
#5: Colorado-Wyoming-Nebraska
Some or all of them may be located on private property so it would be best to reseach that and obtain permission from the owner beforehand. Happy camping and Merry Christmas!
If this goes well, you might want to visit all
