I’m usually not a cave person, but Carlsbad Caverns is impressive enough to warrant a post. The hike into the caverns is relatively easy and on a very maintained, popular trail that only requires 800 feet of elevation gain and loss. The cave system has more than 100 rooms, many of which are still being explored and aren’t open to the public. My favorite is the Big Room, which is a large limestone chamber that’s almost 4,000 feet long, 625 feet wide, and 255 feet high. It’s completely covered in dramatic chandelier-like formations and columns that span most of its height.
