My girlfriend and I decided on an impromptu hike on a Saturday afternoon in early December. We started at the trail head on Panthers Den Ln at approx. 3 pm. We were able to make it to the den where we found amazing rock formations and passage ways. I've lived in Southern Illinois all my life. These are some of the best and most unique rock formations in our beautiful area. We had to turn around after exploring the panthers den due to lack of daylight, but we will be back soon to continue on.
