Thanks to its volcanic grounds and its magic geographic bas-relief, Milos is a natural geologic park ready to be explored.

For all those interested in such an extraordinary tour, the Mining Museum of Milos organizes geologic walks to the most important locations of geological and mining interest on the island. (For more information visit: www.milosmminingmuseum.com or call at tel.: 0030 22870 21620).

We recommend the following footpaths that present a geologic and mining interest:

Route A’

-          “Conference Center of Milos-Yiorgios Iliopoulos”

The building used to be a factory for the processing of kaolin. It was renovated by the company ORYMIL S.A. It is in full operation since 2000.

-          Kanavas Factory

A factory for the processing of bentonite and port installations for loading, owned by the company S&B Industrial Minerals S.A.

-          Kanavas Fumaroles

Submarine leaks of hot gasses and the gushing of hot water of a temperature from 35-75 C. They are used as hot springs.

-          Alyki /Salt-pan

Old facilities for the production of salt, through natural evaporation of sea water.

-          Alyki Spa

Ancient spa cave. Chlorinated hot spring.

-          Geothermic Plant

A plant for the production of electric power, with motive power the pressure of the geothermic liquids in the area that used to rise to the surface by P.P.C. drillings. It functioned for a limited time period experimentally and it was abandoned mainly due to technical reasons.

-          Fylakopi- Papafragas

The development of Fylakopi, the prehistoric city of Milos, according to many researchers is attributed to the trading of obsidian. Papafragas was created by volcanic tuffs having as main component the fragments of pumice (pumice-stone).

-          Zefyria or Hora

A medieval city of Milos. It flourished till the end of the 17th century. The inhabitants abandoned the city because of the volcanic fumes and the epidemics. In the area there is one of the world’s best geothermic fields.

-          Installations of the company S&B Industrial Minerals S.A., Voudia

Here, in 1934, the Company began its activities in Milos, for the exploitation of silver and barite. In 1950s the processing of bentonite, kaolin and pearlite began. Today there are modern installations for the processing of pearlite and bentonite, of the biggest ones in Europe. From the loading bridge 95% of the production is exported worldwide.

-          Aggerias Mine

One of biggest bentonite mines in the world. The exploitation began in 1985 and the average annual mining is one million tons. The different colors that can be seen are due to the different material quantities and they are created by the iron oxides.

Route B’

-          Sarakiniko

A volcanic formation, the shape is mostly caused by the sea erosion and the rainwater. The presence of sea fossils is obvious.

-          Fyropotamos

A plant for the processing of the mineral kaolin in the 1960s.

-          Trahilos

Remains of volcanic activity.

A pearlite mine of the company S&B Industrial Minerals S.A., where the simultaneous exploitation and restoration of the landscape takes place (restored gradients by the sea).

Route C’

-          Hivadolimni

An old pearlite mine restored by the company S&B Industrial Minerals S.A.

-          Tsigrado

A plant for the production of pearlite owned by the company S&B Industrial Minerals S.A.

-          Fyriplaka crater

Remains of the last volcanic activity on the island.

-          Kalamos

A characteristic sample of fumaroles’ action on the island. The overheated steams are released by wheezing from the underground leaving accretions of salts and sulphur.

-          Aghia Kyriaki

Traces of mineral activity in the classic antiquity era and in the Roman period.

Other Important Sights

-          Glaronisia

Andesitic lava. Characteristic columnar splitting with pillars of mainly pentagonal segmentation, indicative of the freezing in minor depth.

-          Kleftiko

White tuffs of a characteristic stratification. The pirates used it as a refuge.

-          Vani

A slow mine for the exploitation of manganese of an important geologic interest.

-          Demenegaki

Prehistoric obsidian mines

-          Sulphur mines (Theioryhia)

Deserted mining tunnels and a plant for the processing of sulphur.
