The Green River flows through one of the most unique, and popular destinations in all of Kentucky, Mammoth Cave National Park. Flowing through the heart of the park, a float trip on the Green is one of the very best ways to experience Mammoth Cave. The total length is over 20 miles, and makes a good multiday trip, but there are also plenty of options to make shorter trips as well. Those taking overnight trips on the river may camp on islands, or within the floodplain of the river. As with all of Kentucky Blue Water Trails, fishing is a main attraction for the Green River. Catfish and smallmouth bass are the favorite target of many anglers on this stretch of water. There is also access into the park via the Nolin River. This provides roughly a nine mile float from the tailwater recreation area to Houchins Ferry within the park. There are several outfitters in the area that offer guided trips and boat rentals.
