Also known as the sea lake of Mesolongi, this salty-water lagoon offers amazing scenic views and was formed by the sandy ridge rising from the deposits of the Acheloos and Evinos rivers, along with their deltas. A sand ridge called Louros also likes between the lake and the Gulf of Patras. Fishermen in past decades have built reed houses on stilts around the lagoon, almost looking Asian in their originality. Salt farms abound in the area, so do fish farms for eels and trout. The lake is also ideal for bird watching (see relevant section under Aitoloakarnania).
