Hornos Island is the southernmost of the Hermite islands. Its soil is made up of hard peat and granite layer that make it possible arrive in the crag after which the cape is named. There is abundant vegetation and in the south extreme there is a crag 425 metres high wich falls to the sea like a steep dark cliff.
Next to the island black rocks and craggy islets emerge and near them reefs make us think about the existence of other montanious peaks near the surface that must have caused many ships to sink during the typical storms of the area. In the "Monumental Lighthouse Hornos Island" there is the staff of the Chilean Navy and in the eastern side there is a pair of piers for boats and areas to cast anchor, but in order to sight land an previous allowance is needed.
