Kotychi and Strofylia Wetlands National Park, Coastal national park in West Achaea Municipality, Greece.

The Kotychi and Strofylia Wetlands National Park runs from Cape Araxos south to the mouth of the Melissos River, a strip rarely wider than 5 km along the Ionian Sea. Its core is the Strofyliá forest, about 2,000 ha of stone pines and Aleppo pines crossed north to south by a canal and dotted with ponds. Three lagoons lie beside it: Kotychi (750 ha), Prokopos (450 ha) and Kalogria (450 ha).

The area was recognized as a Wetland of International Importance under the Ramsar Convention in 1975 and received national park status in 2009. This formal protection marked a key milestone for safeguarding one of southern Europe's most vital habitats for migratory birds.

Kotychi Lagoon is fed by eight small streams and yields over 63 tonnes of fish a year (2010 figure), making it one of Greece's main lagoon fisheries. The Strofyliá pine forest is crossed north to south by a canal, and the Kalógria lagoon is also called the lagoon of Pápa or Áraxos.

The park stretches from Cape Araxos south to the mouth of the Melissos, no more than 5 km wide, so a car helps link the Strofylia forest, the Kotychi lagoon and the Black Mountains. The Strofylia forest is crossed north to south by a canal and dotted with ponds. The management body, based at Lapas, was set up by ministerial decision in 2002.

The Strofylia Forest covers about 2,000 hectares of stone pine (Pinus pinea) and Aleppo pine, described as Greece's largest stone pine forest and one of Europe's most important. A canal runs north to south through it, and small ponds dot the woodland between the dunes and the lagoons.
