Stillhouse Hollow Falls State Natural Area in Summertown, Tennessee, protects Stillhouse Hollow Falls and the surrounding landscape. Its centerpiece is a 75-foot waterfall accessible by a walk of about two-thirds of a mile from the entrance. The land was acquired by the Tennessee Parks and Greenways Foundation and later transferred to the state of Tennessee. On June 3, 2006, it was formally designated a natural area under the Natural Areas Preservation Act of 1971, ensuring lasting protection for this scenic site.
