Stefanos Crater is one of the largest and well-preserved hydrothermal craters in the world. It is a attraction for tourists and is within a 4 km caldera in the center of the island.
The view of the valley and the crater stuns every visitor, gazing at an unparalleled beauty of unprecedented beauty. As someone approaches the crater, one senses the smell of the brimstone, even from the road.
If you walk to the center of the crater, you will feel that you are walking on a different ground than you are used to, giving you the feeling that the floor is hollow. This is easily understood by someone knocking on the bottom and is like knocking on a door.
It is definitely worth going down to the lowest point to get to know and feel the crater up close, as the experience is unprecedented. The ideal time to visit the crater is early or late in the year, avoiding the high summer temperatures.
The crater is about 300 meters in circumference, 27 meters deep and ellipsoid-shaped. The exact age of the crater is not clear, however, because it is found in loose and soft rocks, easily eroded by weather, and does not appear to be older than 3,000 to 4,000 years.
When rainwater enters the interior of the crater, a few meters below its surface, it meets temperatures above 100 degrees Celsius. Thus, it begins to heat up and converts to steam, which exerts pressure on the surface of the crater and causes small explosions, creating round funnels, the holes, that is, in the crater. Along with steam are other gases, one of which is hydrogen sulphide, which is due to the characteristic odor in space.
It used to be called Megalo Aloni or Akolos.
You can approach the point from two paths.
If possible, you can approach the point from one route and return from the other, and both are very beautiful routes.
