Carlsbad caverns are really something
Carlsbad Caverns were great. About the neatest place I had ever seen. I would say get there early in the day and just go to the main cave area. I also went on the tour that takes you farther into the cave system. A different experience. I went back down after lunch and spent more time. You can stay in one of the nearby motels or camp in a campground to the south a few miles. I recommend the the Caverns to anyone passing through the area. As with any trip in the Sonoran Desert area, plan your mileage carefully, gas stations can be far apart.
