  1. The Oldest Exposed Rock Units in Indonesia: Raja Ampat has the oldest exposed rock unit in Indonesia, going back 443.8-358.9 million years. These ancient rock units bear witness to the region’s geological history and provide a unique window into the Earth’s distant past, telling the story of millions of years of geological evolution.

  1. The Enchanting Tropical Islands: Raja Ampat’s geological richness is complemented by its breath-taking tropical islands. The formation of curiously shaped limestone islands, such as those seen in Wayag, Kabui, and Misool’s eastern islets, is a natural marvel. These islands have been sculpted over time by karstification processes, resulting in a beautiful environment of craggy cliffs, hidden lagoons, and hypnotic blue waters. Immerse yourself in the splendor of this tropical paradise and marvel at the delicate interplay of land and sea as in the Piaynemo cliffs.

  1. Caverns Above and Below the Waterline: Karstification, the process by which limestone dissolves in water, has resulted in a plethora of caverns both above and below the waterline in Raja Ampat. The geopark has a vast network of caves just waiting to be discovered, each with its own distinctive shapes and mysteries. Dive beneath the surface to find underwater tunnels teeming with coral gardens and aquatic life. Explore terrestrial caves above the waterline for indications of prehistoric human presence, including stunning rock art dating back thousands of years.
