When I went to Carlsbads I was simply amazed. I had never been underground in such a vast area. We went on Thanksgiving morning. There weren’t many people there, as you might expect. One of the rangers kept asking me to be quiet. I thought I was being quiet. When I asked another ranger, she said that “normal” conversation could be heard about a quarter of a mile. Just look at the wonders!
The park service offers several tours, some of which are strenuos.We didn’t take a tour. We simply followed the path and throroughly enjoyed ourselves. Going on Thanksgiving Day cut down the crowds considerable and gave us time to meander.
