23 miles, options for shorter floats, travels through heart of Mammoth Cave National Park, fishing for variety of species, camping available along river, cave entrances
The Green River flows through one of the most unique, and popular destinations in all of Kentucky, Mammoth Cave National Park. Flowing throught 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. As with all of Kentucky Blue Water Trails, fishing is a main attraction for the Green River. Smallmouth bass are the favorite target of many anglers on this stretch of water. There is also access to Nolin River via the Green River below Nolin Dam. There are several outfitters in the area that offer guided trips and boat rentals.
