We stopped off at the National Monument for an hour while driving through. We did the smaller of the two walks, which is a mile round walk to the bottom of the rocks, it took us about 50 minutes. The path is paved all the way around for easy walking, though there are a few steps, so those with buggies / wheelchairs may need to double back rather than walk round in a loop.
The bottom of the rocks are covered with graffiti from many different ages - from the pueblos to Spanish to railroad surveyors, as well as the oasis. We picked up a guide from the ranger in the visitor center, and the numbered markers throughout the walk highlight all the important points.
It was interesting and fascinating!
