At Christmas at Natural Bridge Caverns, guests can hear favorite carols echo through Texas’ largest underground cavern. They can also get pictures with Santa “Spelunker” Claus, then round up his reindeer in the outdoor maze. As the sun sets behind the 30-foot tall Christmas tree, a hayride rolls through the hills and families can roast s’mores, enjoy games, music, a giant snow globe, ice skating, and more.
