Trnovo Forest Reserve is Europe’s largest virgin forest, offering pristine wilderness experiences rich in biodiversity and old-growth trees in the Dinaric Alps region.
The Trnovo Forest Reserve, located in southwestern Slovenia, is Europe’s largest virgin forest and one of the best preserved natural forest ecosystems on the continent. Spanning approximately 4,280 hectares within the Trnovo Forest Plateau in the Dinaric Alps, this reserve is characterized by dense, ancient beech and fir trees, alongside diverse flora and fauna that have thrived for centuries without human intervention. The reserve's unique karst terrain features caves, sinkholes, and abundant underground water systems, contributing to its rich ecological complexity. Established as a protected area in 1892, Trnovo Forest Reserve represents an invaluable natural archive for scientific research on forest dynamics, biodiversity, and climate history. Recreational activities in the area include hiking, wildlife viewing, and guided educational tours that emphasize conservation. Its remote character and strict protection regulations limit visitor numbers, preserving the reserve’s tranquility and pristine conditions. Key landmarks include the forest’s towering centuries-old trees, endemic species like the Dinaric vole, and the extensive cave systems that have been studied by speleologists. For visitors seeking solitude and a deep connection to one of Europe’s last natural climatic refuges, Trnovo offers unparalleled opportunities for immersive outdoor experiences within a primeval forest setting.
