Borneo is the third-largest island in the world and is divided between Malaysia, Indonesia, and Brunei. The Indonesian part of the island makes up around 73% of the island, the Malaysian part is about 26%, and Brunei is about 1% of the island.

Much of the vast island remains covered with primary rainforest and so the best way to explore it is by riverboat. Exploring Borneo is a bit like exploring the Amazon Rainforest by riverboat. One will see how these rainforests are portrayed in movies like the 1997 adventure horror film Anaconda, which have nothing to do with reality.

Why Borneo Is A Priceless Biodiversity Hotspot

Borneo is home to one of the oldest rainforests in the world - although they are fast being cut down. Another of the world's oldest rainforests is the Daintree rainforest in Australia that is also home to incredible biodiversity and is very much a must for anyone visiting the country.

Borneo's rainforest by some estimates is thought to be around 140 million years old - for reference, the dinosaurs only when extinct around 66 million years ago. The coastlines of Borneo are made up of peat swamp forests and the island is tropical sitting on the equator.

  • Age: Borneo's Rainforests are Thought to be Around 140 Million Years Old

Its rainforests are the center of the evolution and distribution of many endemic species. It is an important refuge for endangered animals like the Bornean orangutan, the Borneo elephant, the eastern Sumatran rhino, the Bornean clouded leopard, and the hose's plan civet.

  • Trees: 3,000 Species of Trees
  • Flowering Plants: 15,000 Species of Flowering Plants
  • Birds: 420 Species of Birds
  • Mammals: 221 Species of Mammals
  • Fish: 440 Species of Freshwater Fish
