Tennessee Code Title 11. Natural Areas and Recreation § 11-11-104

(1) State scenic trails, which will be extended trails so located as to provide maximum potential for the appreciation of natural areas and for the conservation and enjoyment of the significant scenic, historic, natural, ecological, geological or cultural qualities of the areas through which such trails may pass. Each of these trails will be limited exclusively to foot use, except that the use by horses or nonmotorized bicycles may also be permitted on segments of scenic trails where deemed appropriate by the department. Because of their extended length, the state scenic trails shall be supplemented by support facilities located only on that part of a trail which is in a state park, recreation area or wildlife management area. Such support facilities may include, where deemed necessary and feasible, primitive shelters, fireplaces, safe water supply, and other related public use facilities. These facilities shall concur with department standards. No open wood fires shall be permitted on state scenic trails except in areas with support facilities specifically designated for such purpose;

(2) State recreation trails, which will provide a variety of outdoor recreation uses in or reasonably accessible to urban areas. These trails may be of the following types:

(3) Connecting or side trails, which will provide additional points of public access to state recreation or state scenic trails or which will provide connections between such trails. They shall be of the nature of the trails they serve.
