Hiking trail Vela Draga, Učka mountain

Vela draga is since 1963 protected as a natural area reserve and five years later as a geomorphological monument. In this canyon are impressive rocks and limestone towers upto 100 meters.
The rocks in the Učka are formed between 140 million years ago and 30 million years ago, and by the organism of shells were formed sediment layers, and by compacting and cementing processes it became solid limestone rocks.
By karstification (melting, abrasion and erosion) the canyon got its form.

The mines are located in the valley of the river Mirna on a hill named Minjera near Sovinjak. They started here with excavations  of the puritanic bauxite  in the 16th century.  In 1780 a Venetian Pietro Turrini  built here a plant for processing bauxite into sulphuric acid and alum that was used among other for tanning leather. The mines were closed  in 1856.

Monfiorenzo quarry, Cave of Fantasy

This old quarry is a fine example of lime sedimentation (Karst phenomenon) over more than 130 million years in the formation of the earth’s crust.

This sedimentation took place through strong sea currents of alga mixed with limestone silt. Between the layers horizontal and vertical grooves with different types of dolomite and inclusions are visible with genetic and diagenetic characteristics.

Since 1986 this quarry is due to its scientific value, a natural monument.
