🏆🏆🏆 Moreau River Prairie — Remote recreation area on the Moreau River in northwestern South Dakota — true isolation on the northern Great Plains
Little Moreau Recreation Area offers remote recreation on the Moreau River in Dewey County — in the sparsely populated northern Great Plains. This is one of the least-visited recreation areas in South Dakota — population density here is less than 1 person per square mile. The Moreau River flows through the Cheyenne River Sioux Reservation, and this area sits near the historic buffalo hunting grounds that sustained the Lakota people for centuries before the systematic extermination of the buffalo herds in the 1870s–1880s.
