COUNTRY FIELD GUIDE
Slovenia treats geological phenomena, minerals, fossils and their sites as potential natural features subject to nature-protection rules. Protected natural monuments and caves can prohibit removing rock, mineral or fossil material, and significant finds can trigger notification duties. This explorer therefore uses site-level permission rather than assuming public access equals collecting permission.

Materials: Wulfenite, Calcite, Galena, Sphalerite
A major Slovenian mineral-heritage stop in the former Mežica lead-zinc mine. Current 2026 operation offers train, bike and kayak mine experiences plus a mineral museum; official tourism material highlights rare orange wulfenite, calcite, galena and sphalerite underground.

Materials: Calcite, Fossils
One of Europe’s major protected karst systems and a useful trust record for the explorer: its spectacular geology is for observation, not specimen collection. Current park law expressly prohibits removing rock, mineral and paleontological samples.

Materials: Cinnabar, Native Mercury
The visitor-accessible entrance to the historic Idrija mercury mine, one of the world’s most important mercury deposits. Current operation includes scheduled guided tours; the geology is dominated by cinnabar ore and native mercury, but this record is intentionally viewing-only.

Materials: Fossils, Dolomite
A globally important Pleistocene cave site above the Idrijca valley, famous for the Neanderthal flute and rich cave-bear/paleontological record. Slovenia upgraded the archaeological park to national-importance monument status in December 2025; this map routes to the public park area rather than exposing research-sensitive excavation positions.

Materials: Fossils, Brachiopod Fossils
A classic Slovenian fossil/geology destination with abundant late-Paleozoic marine fossils exposed along the gorge. It is included as a strong no-collecting record because its current protected-site guidance explicitly forbids excavation, breaking and removal of rocks.
