It is one the most remote and least visited national parks in the US, located in the extreme SW corner of Texas, on the border with Mexico. It is in the Chihuahua desert, hundreds of miles from anywhere. I have been backpacking there twice, and it was a spiritual experience, even for an atheist such as myself. I have always had a fantasy of selling all my crap, picking up stakes and moving there, or at least the immediate vicinity. One of the last truly wild places in the states.
