Boondocking the Southwest
William at Monument Valley
I have boondocked all over the Southwestern US. I found the Shunpikers guide helpful for finding boondocking locations in Texas, and New Mexico. I will probably download the e-books for Arizona and Utah before my next trip.
In Colorado there are tons of national forest and BLM land that I have camped on for free. I have boondocked in several places I have found but I hope they come up with a shunpikers guide for Colorado soon giving out locations that I am unaware of now.
