Conchagua (also known as Cochague) consists of two overlapping stratovolcanoes in a single conical edifice.

Cerro de La Banderas, at 1133 m, appears younger but is dated at 0.41 ± 0.1 Ma.

Conchagua, in Native American indigenous Salvadoran Lenca language, means (Flying Jaguar).

According to historians, the volcano was settled by the Lenca civilization, who worshipped the goddess Comizahual, an indigenous Jaguar Princess.

[citation needed] At the summit is a retreat called El Espíritu de la Montaña, which means Mountain Spirit.
