The craters were named in honor of the German geologist Wolfgang Sartorius von Waltershausen, who mapped Etna extensively in the mid-19th century.
The Betula aetnensis (Etna birch) found here is a relict species from the last glacial period, isolated on the volcano's slopes.
The 1865 eruption that created these cones lasted approximately 73 days and produced a total volume of about 15 million cubic meters of lava.
The seven cones are arranged in a perfect line, following the underlying volcanic fissure that opened during the 1865 seismic event.
The site sits within the UNESCO World Heritage site boundaries designated for Mount Etna.
Monti Sartorius is a group of seven aligned volcanic craters located on the northeast flank of Mount Etna. These 'buttonhole' craters formed during the significant 1865 eruption of Etna. The site is characterized by an extensive field of loose volcanic scoria and lapilli. It is a prime example of pyroclastic cone formation within the Etna Regional Park. The area features the 'Sartorius' birch forest, a unique population of Betula aetnensis that thrives in this high-altitude volcanic environment. The craters reach elevations between 1,660 and 1,700 meters above sea level. Visitors can walk along the crater rims to observe the internal geological structure of the cones. The surrounding landscape consists of solidified lava flows and pioneer vegetation typical of Etna's higher elevations.
The highest point on the rim of the central crater, offering a panoramic view of the seven-cone alignment and the distant Ionian coast.
Wear sturdy hiking boots with excellent grip to handle the deep, shifting volcanic sand and sharp lava rock.
Bring windproof outer layers, as temperatures drop significantly and winds are often strong at this altitude.
Carry at least 1.5 liters of water per person, as there are no potable water sources on the trail.
Attempting the hike in thin sneakers or flip-flops, which offer no protection against sharp volcanic rocks or stability on loose scree.
Access may be restricted or dangerous during winter months due to heavy snow accumulation.
Stay strictly on marked paths to prevent erosion of the fragile volcanic cones and respect the protected endemic flora.
