On the Rivers

Green River water
 
Green River in Kentucky
Over 30 miles of the Green and Nolin Rivers trace through the park and offer a wealth of recreational opportunities. Angle for muskellunge, bluegill, catfish, bass, perch, crappie, and other game fish. Canoe the rivers looking for wildlife, springs and river bluffs. Camp on islands or in the floodplain, or by the river at the Houchins Ferry Campground. Cross the Green River on two ferries – Green River Ferry and Houchins Ferry – two of the few operating rural ferries in the nation.
