We visited Carlsbad Caverns National Park in early April 2025 while staying at the SKP Ranch RV Park in Lakewood, New Mexico. When we visited, advance reservations were recommended. This was an easy on-line process that we had done some weeks in advance. As it turned out, the day we visited was not busy and we could easily have got in without an advanced reservation.
We had previously visited Kartchner Caverns State Park near Benson, Arizona in 2024 which we had thoroughly enjoyed, so we had some idea of the type of “cave decorations” and formations to expect. What we did not expect, however, was the sheer scale of Carlsbad Caverns compared to Kartchner. We read that Will Rogers had described Carlsbad Caverns as “The Grand Canyon with a roof over it,” highlighting the cavern’s immense size and unique geological formations. He also added, “it’s got all the cathedrals of the world in it, with half of ’em hanging upside down,” emphasizing the variety and scale of the cave formations. That certainly captures the majesty of the cave quite eloquently.
There are two options for entering/exiting Carlsbad Cavern. We chose to take the “Natural Entrance Trail” down into the cave, and the elevator to leave once we had completed the self-guided cave tour. The 1.25 mile Natural Entrance Trail was quite steep, and consisted of a series of switchbacks as the natural light soon dwindled and we entered the darkness of the cave with sparse lighting highlighting some of the natural features and formations, and providing just enough light to navigate the trail. Overall, this trail loses 750 feet of elevation — equivalent to walking down a 75-story building. This section took about one hour with frequent photo-stops.
The Entrance Trail took us into the “Big Room”, the largest single cave chamber by volume in North America. The trail that loops around the Big Room is is another 1.25 mile trail but this time relatively flat. It took us about another hour or so to walk it.
It’s difficult to describe the extent and variety of cave decorations that you encounter as your walk through the cavern. The magnificent speleothems (cave formations) that continue to grow and decorate Carlsbad Cavern are due to rain and snowmelt soaking through limestone rock, then eventually dripping into a cave below and evaporating. Those water drops have absorbed gases and dissolved minerals from the soil and limestone above. Wherever that water drop evaporates and releases carbon dioxide in an air-filled cave, a small amount of mineral-mostly calcite, is left behind. Thus, drip-by-drip, over the past million years or so, Carlsbad Cavern has slowly been decorating itself.
The slowest drips tend to stay on the ceiling long enough to deposit their mineral there. Common speleothems found on the ceiling may be stalactites, soda straws, draperies, ribbons or curtains. The faster the dripping, the more likely it is to make some type of decoration on the floor. A wide range of decorations on the cave floor include totem poles, flowstone, rim stone dams, lily pads, shelves, cave pools, and of course stalagmites.
A visit to Carlsbad Caverns is highly recommended. It ranks as one of the highlights of the National Parks we have visited to-date. While it’s difficult to capture the scale of the cave in photographs, the gallery below includes some of the many pictures we took that give a glimpse into the cave and its spectacular decorations.
