Located a short drive time away from the center of Athens

Attica has many hidden <corners> and secrets that you probably don’t know. For example, you may never have heard of volcanoes that used to be active. One of them is located in the area of Agioi Theodoroi on the border of Attica with Corinthia. It is a volcano without an active crater that still maintains intense post-volcanic activity. The reason for Susaki.

The volcano without a crater in Attica

Susaki is located at an altitude of 180 meters above sea level. Today, about 2.5 million years after its last eruption, it maintains intense activity. From this, many tens of thousands of cubic meters of carbon dioxide, methane and hydrogen sized sulphur was released into the atmosphere, while the temperature on its slope reaches even 42 degrees Celsius.

In the area of the volcano there are two gorges which are surrounded by slopes with very impressive volcanic rocks while in them run water fed by springs scattered along them. Susaki is the northern end of the volcanic arc which still includes the volcanoes of Methana, Aegina, Poros, Nisyros and Santorini. And the last volcanic activity in the region may have been 2,700,000 years ago, but the smell of methane and hydrogen sulphide becomes more intense when you approach it.
