Neither of us has ever been to Carlsbad Caverns. We set aside three whole days to explore it since its remoteness in the southeast corner of New Mexico makes it unlikely we’d ever have an opportunity to return. This remoteness is the reason that, although its wonders are many, far fewer visitors show up than at the more popular national parks. It is located in an almost featureless desert, indistinguishable from much of west Texas, but possessing oil deposits underground that supports much of the local economy. You’re more likely to hear a Texas drawl here than not.
The Big Room, Kings Palace, Queen’s Chamber, Papoose Room and others, “rooms” all named by the 16-year-old Jim White who purportedly first discovered the caves, are wondrous to behold. The word cavernous seems to describe The Big Room aptly, an immense chamber big enough to hold six football fields. An almost level, paved walkway allows everyone to enjoy The Big Room. For those so inclined, there are slightly to much-more-strenuous ranger-guided tours that vary from mild climbing, scrambling (sometimes on rocks that seemed coated with candle wax), rope climbing and going through claustrophobic tunnels barely large enough to squeeze through.
Millions of years ago, at a time when the area was more tropical than at present, an ancient reef was transfigured when hydrogen sulfide gas rose from the oil deposits below and mixed with the oxygen in the water from above. The resulting sulfuric acid carved out the caverns in limestone. The decorations we see today—stalactites, stalagmites, draperies, popcorn and the rest (collectively called speleotherms)—are the result of the “normal” process of deposition built up over time by calcium-rich droplets of water. Artfully designed by a Hollywood lighting director many years ago, the major rooms are beautifully illuminated by artificial lights, effects that Jim White never saw that he would likely denounce as removing the “mystery of the caves.” Our favorite tour was the Kings Palace which showcases rooms so elaborately embellished with cave decorations that the word opulence comes to mind.
The other attraction here are the Mexican free-tail bats that fly out from the so-called Natural Entrance about an hour before sunset. The Park Service has installed some high-tech equipment within the cave that can detect when the bats are ready to emerge; it translates the bats’ echolocation sounds to frequencies that humans can hear. At first, over the amphitheater’s PA system, there was a single click or pop; within seconds, there were so many clicks that it sounded like microwave popcorn. Shortly thereafter, the bats emerged in waves, rather than all at once. No photography (nor turning on of electronic equipment of any kind) was allowed during the bat flight. They disturb the bats as they fly out. The park ranger told us that the more impressive sight is the bats’ return an hour before sunrise, when they swoop back (literally dive bomb) into the cave at about 25 mph or more. On the morning of our departure, we rose early and got to the amphitheater when it was still dark. Try as we might, we couldn’t see the bats, even silhouetted against a lightening sky. But we did hear zipping sounds in the air around us, like bullets whizzing by, which we could only assume were the bats returning so fast that we couldn’t see them. A thickening fog also likely obscured our vision somewhat.
The video below from YouTube shows a much larger swarm emerging from the cave than we witnessed. Bat populations ebb and swell, depending on the season.
The closest town with full amenities is Carlsbad City, some 25 miles away from the park entrance. However, right at the intersection of the park road with Highway 62/180, there is a Rodeway Inn and a few services, including an RV park, gas station, convenience store and restaurant. It’s called White’s City, where we chose to stay, only about 6 miles from the visitors center. It’s much more convenient, but which seems to be on most travel sources’ lists of not-recommended places to stay. Our own experience here was not ideal, but not terrible either. Eating at the same restaurant for breakfast and dinner quickly got old.
