Borneo is renowned for its extraordinary biodiversity, ancient rainforests, and unique wildlife found nowhere else on Earth. Among its most fascinating natural attractions are the iconic Proboscis Monkey and the dazzling firefly displays that illuminate the rivers after sunset.

TYH Borneo offers an unforgettable wildlife excursion that combines both experiences into one remarkable journey. This carefully designed tour takes visitors deep into Sabah’s river ecosystems, providing opportunities to observe rare wildlife, enjoy scenic river cruises, and witness one of nature’s most enchanting nighttime spectacles.

Whether you're a nature enthusiast, wildlife photographer, or first-time visitor to Borneo, this adventure promises memories that will last a lifetime.

Encounter the Famous Proboscis Monkey

Borneo’s Most Recognisable Primate

One of the highlights of the tour is the opportunity to observe the remarkable Proboscis Monkey, a species found exclusively on the island of Borneo.

Easily identified by its distinctive oversized nose, particularly among adult males, the Proboscis Monkey is one of the most unusual-looking primates in the world. Scientists believe the prominent nose plays an important role in attracting mates and enhancing vocal communication within groups.

Beyond their unique appearance, these monkeys possess several fascinating characteristics:

• A rounded belly caused by their specialised digestive system
• A diet consisting mainly of leaves, seeds, and unripe fruits
• Strong swimming abilities supported by partially webbed feet
• Social family groups led by a dominant male

Watching these charismatic animals move through the treetops along the riverbanks is a truly unforgettable wildlife experience.

Explore Sabah’s Wildlife-Rich Rivers

TYH Borneo’s river cruises visit some of Sabah’s most productive wildlife habitats, where Proboscis Monkeys are commonly spotted during their feeding and resting periods.

Popular locations include:

• Klias Wetlands
• Weston River
• Kawa-Kawa River
• Kinabatangan River (available on selected extended tours)

As the boat glides quietly along the waterways, guests may also encounter other wildlife such as macaques, monitor lizards, kingfishers, hornbills, and even crocodiles in their natural habitat.

The calm river environment offers excellent opportunities for photography and wildlife observation while surrounded by the beauty of Borneo’s mangrove forests and wetlands.

Protecting an Endangered Species

The Proboscis Monkey is currently classified as an endangered species due to ongoing threats to its survival.

Major challenges include:

• Loss of habitat caused by land development
• Expansion of agricultural plantations
• Pollution affecting river ecosystems
• Human disturbances within wildlife habitats

By participating in responsible ecotourism programs, visitors help support conservation initiatives and contribute to the protection of these extraordinary animals and their environment.

Witness the Enchantment of Borneo’s Fireflies

Nature’s Light Show After Sunset

As daylight fades, another remarkable experience begins. The evening river cruise reveals one of Sabah’s most captivating natural phenomena—the synchronised glow of thousands of fireflies.

These tiny insects create bioluminescent flashes as a form of communication, particularly during mating season. When large colonies gather within riverside mangrove trees, their lights flicker together in perfect harmony, creating a magical display that resembles strings of twinkling holiday lights.

For many visitors, this breathtaking spectacle becomes the highlight of the entire tour.

Why Do Fireflies Glow?

The mesmerising light produced by fireflies serves several important purposes:

• Attracting potential mates
• Communicating with other members of their colony
• Helping identify their own species
• Deterring certain predators

When viewed against the darkness of the surrounding mangrove forest, the collective glow of thousands of fireflies creates a truly unforgettable scene.

Best Locations for Firefly Viewing

TYH Borneo’s firefly cruises typically operate along some of Sabah’s most famous river systems, including:

Klias River

Known for its large firefly populations and excellent viewing conditions.

Kawa-Kawa River

A popular destination offering spectacular sunset views and impressive firefly displays.

Weston River

A quieter location where visitors can enjoy a peaceful and intimate wildlife experience.

As darkness settles over the river, the glowing mangrove trees transform the landscape into a magical natural wonderland.

Supporting Firefly Conservation

Fireflies are highly dependent on healthy ecosystems and are particularly vulnerable to environmental changes.

Key threats include:

• Artificial light pollution
• Destruction of mangrove habitats
• Water contamination
• Excessive use of pesticides
