Situated in south central Kentucky, the Mammoth Cave National Park was established to protect a significant section of Mammoth Cave, the world's longest known cave. There are a variety of tours to choose from, ranging from one to two hours in length, and many are designed to cater to people with a specific interest in history, science, or geology. If you have small children, the Mammoth Passage Tour is the best choice, as it leads along broad pathways in the cave's main sections. Reservations are recommended for most tours, particularly during the spring and fall when school groups tend to come.
