The Energy and Mineral Resources (ESDM) Ministry has officially designated the Dieng Plateau area as a national geopark through ESDM Ministerial Decree No. 172.K/GL.01/MEM.G/2025 on May 7, 2025.

"Alhamdulillah, Dieng has been designated as one of the national geoparks. This is a source of pride for all of us and hopefully it will motivate us, especially in preserving the environment and cultural heritage there," said Banjarnegara Regency Tourism and Culture Office (Dinparbud) Head Tursiman in Banjarnegara Regency, Central Java on May 27, 2025.

He explained that the management of Dieng geopark includes many aspects, such as geology, ecology, etc. The Dieng National Geopark area consists of 23 geological diversity sites (geosites), eight biodiversity sites (biosites), 10 Cultural Diversity sites (Cultural Sites), and six other interesting destinations.

The ESDM Ministry defines a geopark as a sustainable regional development landscape that combines three diversities, namely geological, biological, and cultural diversity. The purpose of its management is to develop the local community's economy based on the protection of the three diversities found in the area.

In addition to presenting stunning natural panoramas from an altitude of around 2,000 meters above sea level (masl), the Dieng Plateau also has a wealth of history and culture from hosting Hindu temples dating from 8th century Common Era (C.E.). Moreover, the temperature in Dieng can even reach 0° Celsius during the dry season.

Notable tourism destinations at the Dieng Plateau include:

1. Warna Lake: The icon of Dieng tourism, the lake's uniqueness is how its color can change depending on the reflection of sunlight since its waters contain sulfur;
