When we arrived at Onondaga Cave, we met our rather tall 6’6” ranger/tour guide Michael Miller. He gave us a preview of what we could expect on the tour. We watched a quick video and were on our way. As we entered the air lock we were taken back by the cool, yet thick 100% humidity. Inside it’s a constant 57 degrees with no breeze so you might want to bring a jacket. Oh, and be sure to wear shoes with a little thicker sole than say, loafers. The cool temps can make your feet quite chilly. Don’t worry about getting dirty – just stay on the path; don’t touch the formations (that can be bad); and prepare yourself for sights by which you’ll be awestruck.We toured the depths of the cave and gazed in awe as Michael explained the dolomite formations, showed us flowstone (calcium formations deposited by flowing water), and pointed out the stalagmites and stalactites in their whites, greens, oranges, grays and blacks. (We remember the differences between stalagmites and stalactites from this little saying: Stalactites cling “tight” to the roof and stalagmites “might” reach up. This place is massive!
