Aquifer Tours NOW AVAILABLE!!

After a long, protracted drought, rain has once again returned to South Texas! Due to these recent heavy rains, water has risen within the cavern and is currently covering the lower walkway. While the water remains above the walkway, the regular North Cavern Tour is closed. In its place, we offer our guests the rare opportunity to see a unique natural phenomenon – a close-up view of an aquifer! Welcome to the Discovery Aquifer Tour at Natural Bridge Caverns!

There is no danger to our guests or to the Caverns because of the high water levels.

The Glen Rose Aquifer is the local underground water reservoir. This aquifer lies beneath the Caverns, and under normal circumstances the water table is not high enough to be seen. However, when heavy rains send large amounts of groundwater seeping into the aquifer (a process known as “recharge”), the water table begins to slowly rise into the lower chambers of Natural Bridge Caverns. The Discovery Tour trail passes through some of these lower passages, and with enough rain, the water table can rise high enough to submerge these walkways. Once the rain stops, the groundwater will slowly recede until it once again disappears into the hidden passages below Natural Bridge Caverns.

These conditions are the result of natural groundwater flow, and we have no ability to predict the duration of this special event. We advise all guests to call and obtain up-to-date information regarding these tours and the current status of the water level within the Cavern.
