Lake Trichonida
Lake Greece's largest natural lake with diverse aquatic habitats
Greece’s largest natural lake, Trichonida lies in Western Greece; anglers, birdwatchers and boaters visit the freshwater expanse and the low hills and villages that frame its shoreline.
Lake Trichonida is the largest natural lake in Greece, located in Aetolia-Acarnania in western Greece. The lake is a freshwater basin of regional ecological and economic importance.
Shallow coastal plains and hills surround the lake, and it supports fish populations, wetlands and a range of bird species; communities around the shore depend on fishing and agriculture. The lake’s open waters and shores offer local recreational opportunities.
Geologically the lake occupies a tectonic basin and has been important to surrounding settlements for centuries; it remains a focal point for regional land use and biodiversity.

- Size: It is the largest natural lake in Greece and covers an area close to 98 square kilometres, offering freshwater habitat and local fisheries.
- Local use: Surrounded by agricultural land and small towns, the lake supports birdlife and traditional fishing communities, with several small ports on its shore.
