Located in western Sarawak, Malaysia, the Sarawak Delta UNESCO Global Geopark sits at a major geological boundary where two ancient landmasses came together more than 200 million years ago, during the breakup of the supercontinent Gondwana. This collision shaped the foundations of Borneo and has led to the Kuching Zone suture, which is a key piece of evidence for how Southeast Asia's landmasses have shifted over time. Today, the geopark is defined by a warm tropical climate and exceptional biodiversity, supported by an extensive river delta system and a landscape that transitions from low-lying plains to higher ground inland. The area preserves a long record of Earth’s history, spanning over 250 million years, during which shifting plates and tectonic forces gradually reshaped Borneo.
