Deep in the interior of Sabah lies one of Borneo’s most mysterious and least-explored wildernesses: Maliau Basin, known as the Lost World of Sabah. This remote rainforest amphitheater, almost perfectly circular and encircled by cliffs, has remained untouched for millions of years. For adventurers seeking the raw beauty of Borneo, trekking Maliau Basin is a once-in-a-lifetime experience.
Maliau Basin covers 588 square kilometers of pristine rainforest, making it one of the last true frontiers of Borneo. Its remoteness means only a small number of travelers venture here each year, keeping its ecosystems intact and its mystery alive.
Over 80 species of mammals, including orangutans, gibbons, sambar deer, and the elusive clouded leopard.
Around 300 species of birds, making it a paradise for birdwatchers.
Thousands of plant species, from giant dipterocarp trees to delicate orchids and pitcher plants.
The crown jewel is the seven-tiered Maliau Falls—one of Borneo’s most breathtaking natural wonders. Along the trek, hikers also discover Giluk Falls, Ginseng Falls, and hidden jungle pools perfect for cooling off.
Reaching Maliau Basin is part of the adventure.
From Kota Kinabalu or Sandakan: Fly or drive to Tawau or Lahad Datu, then continue by 4WD (4–5 hours) to the Maliau Basin Study Centre (MBSC).
The journey includes rugged off-road sections, adding to the expedition feel.
Most Maliau expeditions take 4–5 days, covering around 46 km of jungle trails.
Day 1: Arrive at Maliau Basin Study Centre and take a short introductory walk before overnighting at the base.
Day 2–4: Trek through dense rainforest, cross rivers, and climb ridges. Stay at basic jungle camps like Agathis, Nepenthes, or Ginseng Camp. Visit waterfalls such as Giluk and Ginseng Falls before reaching Maliau Falls.
Day 5: Trek back out to Agathis and return to MBSC.
