The Lime Hollow Nature Center encompasses nearly 430 acres of beautiful rolling hills and shallow glacial valleys (kame-and-kettle topography), forests, fields, streams, numerous ponds, including many marl ponds and vernal (seasonal) pools, a peat bog, and a great diversity of flora and fauna. Located on the border between Cortland and Tompkins Counties, in beautiful upstate New York, they offer more than 12 miles of open-to-the-public, entrance-fee free trails, public nature programs, and adventure day camps for youth.
