Geography and Landscape

Gunung Mulu National Park is situated in the rugged interior of Borneo, and its landscape is dominated by dramatic karst formations. The park's geology is the result of millions of years of geological activity, which has shaped the terrain into a remarkable combination of limestone mountains, vast cave systems, and dense rainforests. The park's centerpiece, Gunung Mulu itself, is an imposing sandstone mountain that forms the highest point in the region. The towering peak is flanked by other prominent mountain ranges, including Gunung Api and Gunung Benarat, which contribute to the park’s rugged topography.

The geographical features of Gunung Mulu National Park are a result of complex geological processes. Over 60 million years of tectonic activity and erosion have created an intricate network of limestone caves, cliffs, and valleys, which give the park its striking appearance. The region's karst landscape is particularly unique, with its limestone pinnacles, rock spires, and underground rivers. This geological history has also given rise to a variety of ecosystems, ranging from lowland tropical rainforests to montane forests at higher elevations.

The park is situated at the meeting point of the tropical rainforests of Borneo and the more temperate montane ecosystems. These contrasting environments create a mosaic of habitats that support an incredibly rich diversity of species. The climate of the area is typically humid, with high levels of rainfall throughout the year. The combination of high rainfall, dense forests, and a variety of habitats makes Gunung Mulu one of the most biologically diverse areas on the planet.
