I've been there several times as a kid and and adult! My mom was born in Carlsbad, New Mexico and then moved to El Paso. I grew up in El Paso, Texas; so we lived fairly close to there. My husband, kids and I visited there when we were back visiting family in El Paso when our kids were around 5 and 8 years old. I love Carlsbad Caverns! It is so amazing! I've walked down and back up. I've also ridden the elevator back up. My mom tells the story of my grandmother, her mom, visiting there when they would lower you in a large basket to look around! Yikes - that was before they had made the pathways and installed an elevator! Also, I think it is so amazing to see the bats emerge!
