The world's longest known cave system is found right here in Kentucky. In the south-central region of the state, Mammoth Cave National Park attracts curiosity seekers from around the world. With more than 400 miles of caves explored, the vast chambers and complex labyrinths earned it the name mammoth. There are also plenty of adventure above ground as well. Mammoth Cave National Park is home to an extensive series of trails. All trails are open to hiking, about 60 miles to horseback riding, and 25 miles to biking. The Green River flows for 26 miles through Mammoth Cave National Park, as does the Nolin River for 6 miles. Overnight paddling trips are popular for canoes and kayaks, and the fishing in these rivers can be good as well. Backcountry camping is also permitted with a backcountry use permit that may be obtained free of charge at the Park Visitor Center. The Green and Nolin rivers located in the park offer blue way users miles and miles of navigable and fishable water. Mammoth Cave National Park is a must see for out of state visitors, and Kentuckians alike.
