Discovered near San Antonio in 1960, the Natural Bridge Caverns are the largest known caverns in Texas. The site takes its name from a 60-foot (18-meter) natural limestone slab bridge that spans the entrance. During excavations, artifacts dating back to 5000 BC were unearthed, hinting at the area’s rich prehistoric past. Today, visitors can explore the extensive underground cave system and enjoy a range of adventures, including guided tours and an enormous outdoor maze. The caverns continue to be explored, offering a unique and evolving experience for those who visit.
