The formations in Harrison’s Cave are the results of water dripping through the rocks which means that, gasp, water drips through the rocks. Although you are sitting in a buggy for the tour, you will get wet. Water will drip quite heavily on your head. It might be nice to have a rain slicker with a hood, or you can do as we did, and simply dry off in the sun afterward. You will get the opportunity to get out of the buggy, and tramp around a bit, so wearing shoes with a solid grip is advised (again it is wet and slippery). The hiking trails around Harrison’s Cave are wonderful and not to be missed so these shoes with a grip will come in handy there also.
