I was in the San Antonio area with my family and since visiting the the Natural Bridge Caverns was on my list of things to do, we decided to make it happen. In case you were wondering, natural caverns are caves formed naturally by the weathering of rock. Before the tour started we were given "the talk" about the do's and don'ts of the caverns; we were told not to touch the walls of the caverns because of oil on our fingers and it being harmful to the rocks.
Y'all it's so freaking beautiful inside the caverns, it's a wonderful thing to experience. The caverns are about 180 feet deep and some of the steps are steep and wet because it's very humid in the caverns. I definitely recommend stretching before, dressing comfortably and wearing a pair of walking shoes with a good grip. We didn't do any of the other fun activities Natural Bridge Caverns have to offer like the maze or the zip line because, honestly my nerves would have been shattered (maybe next time) lol but hiking the trail of the caverns was Discovery Tour was enough. Nature never ceases to amaze me.
