About this spectacle

Mount Apoi Geopark, a UNESCO Global Geopark on Japan's Hokkaido island in Samani County, showcases remarkable geological diversity shaped by ancient oceanic crust and serpentinite bedrock. Visitors traverse alpine terrain where peridotite and dunite formations emerge at the surface — rare ophiolite exposures that scientists travel globally to study. The mountain's unusual mineral-poor soils have fostered a unique endemic flora, with delicate alpine wildflowers clinging to rocky slopes that would otherwise appear barren. Hiking trails lead through pristine forest before opening onto exposed ridgelines with panoramic views of the Pacific Ocean and Hidaka mountain range. The interplay of geological rarity and endemic biodiversity creates an unusually intimate wilderness experience — smaller and quieter than most national parks, yet scientifically and visually compelling for those who seek it out.
