The Kotichi lagoon is located in the Prefecture of Ilia northeast of the town of Lechena while the coastal forest, the Strofylia wetland, is further north, in the Prefecture of Achaia.
It is essentially a network of lagoons, lakes, swamps and forests along the northwest coast of the Peloponnese.

Kotchi Lagoon is not deep (30-40 cm) and has fresh water.
It is the largest lake in the Peloponnese and is characterized by great biodiversity.
Wildlife is of great ecological importance as the lake is at the southwestern end of the western migratory crossing of many migratory birds.

Near the lake is the coastal forest of Strofylia, which covers an area of ​​15 km long and 0.5 – 3.5 km wide.

Due to its particular importance for the life and breeding of many aquatic birds, the area is protected by the Ramsar Convention (Convention for the Protection of Water-Areas of International Interest) and belongs to the European Union’s List of Special Protection Areas.
