Be prepared for a steep downward walk. It takes about 35-45 minutes to walk at a good clip. The swallows are flying in and out of the natural opening and it makes for an exciting start. Once in the cave, the drop continues until you feel like you are deep inside the earth. The formations are visible soon after it is dark and the walk to the rest area continues to be challenging. Before you disappear into the darkness, take one look back at the sky for a truly memorable scene.
This is my third time to the caverns and it always as beautiful and mesmerizing as the first time I saw them.
