The lagoon of Gialova and the beaches of Voïdokilia and Divari North of Navarino Bay, near the village of Gialova, the Gialova wetland (Osman-aga lake) is one of 10 major lagoons in Greece. Part of the Natura 2000 network, it is considered a place of remarkable natural beauty and as one of the important bird areas in Europe. It has also been listed as a 1500-acre archaeological site, lying between Gialova and the bay of Voidokilia. Its alternative name of Vivari is Latin, meaning 'fishponds'. With a depth, at its deepest point, of no more than four meters, its pond constitutes an ornithological reserve of exceptional importance in Europe, as it is the southernmost stopover of birds migrating between the Balkans and Africa. It gives shelter to no fewer than 270 bird species, among them greater flamingos, glossy ibis, grey herons, great egrets, little egrets, Eurasian curlews, golden plovers, black-winged stilts, great cormorants, common kingfishers, ruffs, garganeys, but also Audouin's gulls and birds of prey (lesser kestrels, ospreys, peregrine falcons and imperial eagles). It is Gialova, too, which plays host to a very rare species, nearing extinction throughout Europe, the African chameleon. The observation post of the Greek Ornithological Society allows visitors to find out more and to watch the shallow brackish waters of the lake; they can walk the paths that circumscribe Gialova's different ecosystems.At the western end of the lagoon is the small bay of Voidokilia, whose cove-shaped beach is regularly ranked among the most beautiful in the world. It is bordered on one side (to the east) by the Divari lagoon from which it is separated by a dune bank, on the other side (to the west) by the Ionian Sea onto which it opens, and finally on a third side (to the south) by the Navarino bay. The beach is also part of the Natura 2000 network. It is free to access and can be reached by two routes: either by a road from the village of Gialova which crosses the Divari lagoon, or by a path which crosses the village of Petrochori. On the northern promontory at the entrance to the Voidokilia lagoon is a Mycenaean beehive tholos tomb known as "Thrasymedes', the son of king Nestor. On
