Overview
What is the world's third-largest island, shared by three countries, home to some of Earth's oldest rainforests, and one of the richest regions for biodiversity? The answer is Borneo. Known for its extraordinary wildlife, lush tropical forests, and cultural diversity, Borneo is one of the planet's most remarkable natural landscapes.
Borneo is a large island in Southeast Asia shared by Indonesia, Malaysia, and Brunei Darussalam. Covering approximately 748,000 square kilometers (289,000 square miles), it is the largest island in Asia and the third-largest island in the world after Greenland and New Guinea. The island is internationally recognized for its ancient rainforests, diverse ecosystems, Indigenous cultures, and exceptional biological richness.
Today, Borneo continues attracting scientists, conservationists, ecotourists, and adventurers through its rainforests, national parks, rivers, mountains, and wildlife while balancing economic development with environmental conservation.

Why Borneo Matters
Borneo is one of Earth's most important biodiversity hotspots. Its tropical rainforests, some estimated to be more than 100 million years old, provide habitats for thousands of plant and animal species, many of which are found nowhere else. The island is famous for iconic wildlife including orangutans, pygmy elephants, clouded leopards, proboscis monkeys, hornbills, and countless endemic plants.
The island also holds great cultural significance. Hundreds of Indigenous communities, including the Dayak peoples, have lived on Borneo for centuries, developing rich traditions, languages, craftsmanship, and sustainable relationships with the surrounding forests and rivers. Today, Borneo remains an important destination for ecological research, conservation, and cultural tourism.
Whether you're trekking through ancient rainforests, climbing Mount Kinabalu, cruising along jungle rivers, observing orangutans in the wild, or learning about Indigenous cultures, Borneo offers unforgettable experiences where nature and human history are deeply connected.

What Makes Borneo Different?
One of the world's greatest biodiversity hotspots
Borneo supports an extraordinary variety of wildlife and plant life. Scientists continue discovering new species across the island, while its forests provide critical habitats for endangered animals including orangutans, Bornean pygmy elephants, sun bears, clouded leopards, and proboscis monkeys.
Shared by three countries
Unlike most of the world's largest islands, Borneo is divided among three sovereign nations: Indonesia, Malaysia, and Brunei Darussalam. Each region contributes unique cultures, landscapes, conservation programs, and economic activities while sharing responsibility for protecting the island's natural heritage.
Home to ancient tropical rainforests
Borneo's rainforests are among the oldest continuously existing tropical forests on Earth. These ecosystems help regulate regional climate, store vast amounts of carbon, support freshwater systems, and sustain one of the planet's richest concentrations of biodiversity.
