Kebumen UNESCO Global Geopark
Celebrating Earth Heritage
Kebumen UNESCO Global Geopark offers a remarkable record of Earth’s geological past, showcasing the oldest rock formations on the island of Java. A key feature is the Karangsambung site, a natural laboratory of oceanic and continental margin rocks dating back tens of millions of years. These rocks illustrate plate tectonic theory, showing how an ancient ocean floor was pushed up to the surface. The area reveals fossils from ancient marine and prehistoric ecosystems, as well as fascinating caves and underground rivers.
