Connecting or side trails within park, forest, and other
recreation areas administered by the Secretary of the Interior or

by the appropriate Secretary as components of a national
recreation, national scenic or national historic trail. When no
Federal land acquisition is involved, connecting or side trails may
be located across lands administered by interstate, State, or local
governmental agencies with their consent, or, where the appropriate
Secretary deems necessary or desirable, on privately owned lands
with the consent of the landowner. Applications for approval and
designation of connecting and side trails on non-Federal lands
shall be submitted to the appropriate Secretary.
