South Cumberland State Park is a state park in the middle and southeast portions of Tennessee on the Cumberland Plateau. The park is one of Tennessee's newer state parks, established in 1978. It is a collection of nine discrete tracts scattered across Franklin, Marion, Grundy and Sequatchie counties, totaling approximately 30,899 acres (as of 2020). Twelve trailheads provide hiking access to most sections of the park, which protects a series of unique ecosystems on the escarpments and in the ravines of the Southern Cumberland Plateau. There are over a dozen large waterfalls in the park, the tallest of which is Foster Falls, in Marion County.
