Like everything in Texas, the Natural Bridge Caverns are big. In fact, they are the largest known caverns in the state. Discovered near San Antonio in 1960, the Natural Bridge Caverns’ name is taken from the 60-foot (18-meter) natural limestone slab bridge that spans the entrance. During excavations, artifacts dating back to 5000 BC were unearthed. While the caverns are still being explored today, visitors can enjoy adventures ranging from underground cave tours to an enormous outdoor maze.
