Conchagua volcano (also known as Cochague) is an eroded stratovolcano on the western side of the Gulf of Fonseca in at the southeastern tip of El Salvador.
The main summit of Conchagua is Cerro del Ocote, but the secondary summit Cerro de La Bandera to the ENE of the elongated volcanic edifice seems to be younger.
It is uncertain whether the volcano should be considered still active, but it has certainly not erupted for a long time. There is fumarolic activity on some spots of both peaks.
