The smallest and southernmost of the major islands is Hornos Island, the location of Cape Horn. The islands are located south of the Wollaston Islands and separated from them by the Franklin Channel. The islets Terhalten, Sesambre, Evout and Barnevelt are located easterly and are not considered part of the Hermite islands.
