8,600 acres of quiet, rolling hills marked with flint and limestone dominate the landscapes around Manhattan KS. Kansas State University Division of Biology manages the land that is owned by the Nature Conservancy. Extensive research is conducted here on prairie ecosystems. Open 365 days a year to the public, there are three varied trail-lengths beckoning hikers to explore the scenic vistas and natural wildlife. Trails of 2.5, 4.4 and 6 miles lead visitors into the flint hills. Trails are for humans only, no bikes, and are open from dawn to dusk. This experience will remain unique to the largest remaining tract of tallgrass ecosystem in the world, so step out our back door and see what the prairie is all about for yourself!
