More than 77 people have been killed, including 23 children, and at least 185 others injured due to the raging fire.
In Mati, about 30km outside of Athens, rescue workers placed the dead in body bags. The charred remains of 26 people, including small children, were found huddled together on early Tuesday morning near a steep cliff overlooking the jagged coast, Al Jazeera repored.
The head of Greece’s Red Cross said it appeared the group tried to find an escape route, "but unfortunately ... didn’t make it in time"
"Instinctively, seeing the end nearing, they embraced," Nikos Economopoulos told local Skai TV.
Elsewhere in the village, desperate people rushed to the seashore, wading into the water to escape the encroaching blaze.
Survivors Mati told Al Jazeera of seeing dead bodies scattered among the debris. The cause of the fires is still unknown.
Greek Prime Minister Alexis Tsipras declared three days of mourning, saying the country is experiencing an "unspeakable tragedy".
