Klokova (Greek: Κλόκοβα, also known as Paliovouna (Παλιοβούνα)) is a mountain in the southeast of Aetolia-Acarnania, in western Greece.

[2] Its highest point is 1,039 m.[1] The mountain is located nearly 6 km west of Antirrio and sits on the northeast shore of the Gulf of Patras.

A nearby mountain range is Arakynthos to the northwest, separated from Klokova by the river Evinos.

[2] Nessus tried to carry Deianeira across the Evinos river, which led Hercules to kill him.

The decomposition of their bodies made water flowing at the foot of the hill to be ""bleak and with blood clots...".
