Maliau Basin – The Lost World of Borneo’s Ultimate Rainforest Adventure

Hidden deep in the heart of Sabah lies one of Southeast Asia’s last great wilderness frontiers — Maliau Basin, often called “Sabah’s Lost World.” This vast, untouched rainforest is not a place you casually drop by on a day tour. It is remote, raw, muddy, and spectacular — exactly the kind of place Lost Borneo Tours loves to explore.

If you’re looking for manicured boardwalks and café stops, this isn’t it. But if you dream of towering waterfalls, ancient rainforest, wildlife encounters, and sleeping in simple satellite camps surrounded by jungle sounds, welcome home.

What Makes Maliau Basin So Special?

Maliau Basin is a Class I Protected Forest Reserve, meaning it remains largely untouched by modern development. Its bowl-shaped landscape covers more than 588 square kilometres of pristine rainforest, with steep ridges forming a natural fortress around the basin.

This isolation has allowed ecosystems here to evolve with minimal human impact — a dream for adventure seekers, researchers, and anyone who believes the best places require effort to reach.

And yes, getting there involves 4WD journeys, and a healthy sense of humour.

A Jungle Shaped by Water – Waterfalls Everywhere

If waterfalls were currency, Maliau Basin would be extremely wealthy.

Iconic Waterfalls Inside Maliau Basin

Some of the most stunning waterfalls in Sabah are hidden within this basin, including:

• Maliau Falls – a dramatic multi-tier cascade deep in the core zone

• Takob-Akob Falls – wide, powerful, and endlessly photogenic

• Seven-Tier Waterfall – nature’s version of a stairmaster

• Giluk Falls – peaceful, scenic, and perfect for a refreshing dip

Most treks involve river crossings, slippery roots, and muddy trails — but every waterfall feels like a private reward earned through sweat and laughter.

Lost Borneo tip: The muddier you get, the better the waterfall ahead.

Wildlife Encounters – Subtle, Wild, and Unscripted

Maliau Basin is not a zoo. Wildlife sightings here are never guaranteed, but that’s exactly what makes them special.

What Wildlife Might You Spot?

With patience, luck, and experienced jungle guides, sightings may include:

• Orangutans swinging quietly through the canopy

• Bornean gibbons calling at dawn (your natural alarm clock)

• Bearded pigs and sambar deer along forest trails

• Clouded leopards (rare, elusive, legendary)

• Hornbills, pittas, and endemic bird species

Wildlife here is shy and intelligent — which means when you do spot something, it feels like a true privilege rather than a performance.

Lost Borneo honesty: We promise adventure, not animals on cue.

Sleeping in Satellite Camps – Real Jungle Nights

Forget luxury resorts. Maliau Basin adventure is about simplicity and immersion.

What Are Satellite Camps Like?

Satellite camps around the basin are basic but comfortable, designed for explorers rather than spectators. Expect:

Dorm-style rooms or raised platforms

Mosquito nets and thin mattresses

Cold showers (also known as “wake-up therapy”)

Limited electricity or solar power

Meals prepared by dedicated camp staff

At night, the rainforest takes over. Cicadas, frogs, distant calls, and the occasional branch snapping remind you that you are a guest here.

Lost Borneo humour: No Wi-Fi, but excellent connection to nature.

Trekking Maliau Basin – Challenging, Rewarding, Worth Every Step

Maliau Basin trekking is moderate to challenging, depending on route and weather. Trails can be steep, muddy, and physically demanding — especially after rain.

What to Expect on the Trails

Jungle trekking through primary rainforest

Slippery rocks

Elevation changes and long hiking days

Frequent stops to admire plants, insects, and scenery

A lot of laughter when someone slips (safely)

Our Lost Borneo Tours jungle rangers are highly experienced, trained in safety, navigation, and jungle survival — and they know when to push and when to pause.

Best Time to Visit Maliau Basin

Maliau Basin can be visited year-round, but conditions vary.

Seasonal Considerations

Dry season (March–September): Better trekking conditions, easier river crossings

Wet season (October–February): Lush scenery, powerful waterfalls, more mud (fun for some, challenging for others)

Lost Borneo advice: Rain makes the jungle beautiful — and adventurous.
