“Drop into a world of wonder”

Descend into the depths of Onondaga Cave State Park and drop into a world of wonder: towering stalagmites, dripping stalactites, and active flowstones help make the cave a National Natural Landmark and illustrate why Missouri is often called “The Cave State.” Visitors can take guided tours into the underground wonderland. But if you prefer the surface, the park’s Vilander Bluff Natural Area provides a panoramic view of the Meramec River. Easy access to the Meramec River allows visitors to canoe or fish in a bucolic setting.

I went on the cave tour in summer 2017. Onondaga caves have a lot of steep paths which left a lot of the tour group out of breath, but I think most of our breaths were taken away by the 1 & 1/2 hour stalagmite scene. The tour guide was knowledgeable of the caves and seemed very enthusiastic about her job. She even turned the lights off for a minute and allowed us to experience complete silence and darkness; it was cool experience, cooler than the caves temperature (50F year round, so bring a jacket!). They make everyone clean their shoes and kindly inform people who travel to other caves to not wear the same articles of clothing in order to prevent spread of fatal disease in the bat population. There was an admission price of 20-something dollars per adult, but it is definitely a sight worth seeing especially for those first-time cave visitors.

I thoroughly enjoyed my cave tour. But very cold underground! Bring a thick jacket or coat, even in the summer.

Although the tour itself is a bit corny and too fast for my pace the cave is actually breathtaking and worth the trip and money.
