Carlsbad Caverns (3225 National Parks Hwy in Carlsbad, New Mexico) is a magic, beautiful place. It's a road trip that I feel is required seeing at least every few years. Walking down the natural entrance is like a pilgrimage to me. A lovely, sacred descent into the earth that bore us.

Famous for its many formations and its signature bat flights, Carlsbad Caverns is a worthy road trip for anyone, but especially families. The wonder on your kid's face is worth the cost of admission alone. However, Carlsbad Caverns is offering several fee free days this year:
