We have been there several times bc it was an easy drive from our house in New Mexico. Your kids will love the caverns! We had to drive through Roswell and so we stopped at the UFO museum there which our son still talks about! We also had fun going to White Sands National Monument. I believe there is a wildlife park in or near Carlsbad you can go to and there is the Living Desert park. The Pecos River is nearby. And there is a lake you can go to nearby...Brantly Lake. I guess I would just look at what there is to do along your drive. Then look up what to do in Carlsbad, NM.
