Koutavos is the name of the lagoon, located south of the bay of Argostoli. Its shape is ellipsoid, it length reaches 6.5 km and the extent of the 1300 acres. It is a wetland with rich flora and fauna (swans, ducks, gulls, etc.).
The shallowness was characterized particularly dangerous in the past (before the bridge was built) because of the marshy nature. Many mosquitoes and swamps made it dangerous for human health and this was a problem for residents of nearby villages who wanted to visit Argostoli.
Today, the lagoon of Koutavos is a tourist attraction and breathtaking greenery for the city of Argostoli. It is a small green paradise near the noisy capital city.
