Enjoy a flight over these craters located in the area of Pelei Argolida. The western crater has a diameter of 215 meters and the eastern 230 meters. These giant imposing craters awe the visitor. From above they are an incredible, eerie, alien spectacle. Scientists are divided over their origin. Others claim that it is a doline (cave top that fell down) - but there is no cave nearby and it must have been huge if it existed - and others claim that it is a meteorite crater, like those on the moon. The absolute silence that prevails inside them is broken only by the chirping of the birds that find shelter in the vegetation that exists inside them.
