Before Danum Valley became a conservation area, no human settlement existed within its 438 square kilometers of lowland dipterocarp forest. No logging, no hunting, no farming - just 130 million years of uninterrupted Bornean rainforest, growing in a bowl-shaped valley where the canopy climbs past 70 meters and the world's tallest tropical tree pierces nearly 100. In a region where deforestation has consumed vast tracts of Borneo's primary forest, Danum Valley is the exception that proves what this island looked like before chainsaws arrived.

The valley is bowl-shaped, ringed by hills that rise to 1,093 meters, and its interior is accessible only through trails that take...

Bornean orangutans move through the upper reaches of the forest, building nests in the dipterocarp crowns and descending occasionally to cross gaps between trees. They share the canopy with Mueller's Bornean gibbons, whose calls echo across the valley at dawn. Below them, Horsfie...

In 2019, researchers discovered a yellow meranti tree in the valley that measured 97.58 meters from average ground level - the tallest tropical tree ever recorded. They named it Menara, which means 'tower' in Malay. The tree was scanned with terrestrial laser technology and drone...

At least 61 species have been recorded within a single square kilometer - one of the richest concentrations of land snails anywhere in the world. The richnes...
