Continue to the Kinabatangan River, home to one of the highest concentrations of wildlife in all of Borneo. After settling into your lodge for the next few days, go on a dusk cruise in search of orangutans, hornbills, slow lorises, western tarsiers, civets, proboscis monkeys, and more. Watch the sun rise as you embark on an early morning river safari cruise to explore this region’s natural beauty and rich wildlife diversity. Before lunch, enjoy another walk through the jungle to search for wildlife accompanied by a talk from an orangutan expert. After lunch, you will embark on a short boat ride and transfer to the famous Gomantong Caves to spend the afternoon exploring these caves and their surroundings.

Drive to one of the most biodiverse regions of Borneo, the Tabin Wildlife Reserve, which boasts an impressive 220 bird species as well as the wild banteng cattle. You will explore the reserve in 4x4 off-road vehicles in the hope of witnessing leopard cats, marbled cats, flying squirrels, and binturong bearcats in their natural habitats. Participate in a morning trek to the mud volcano, where salt-enriched mud bubbles up and attracts many different animals.

You will travel the scenic road up to Kadamaian Valley on the way to Kinabalu National Park. Enjoy an afternoon birding in the park. Kinabalu National Park is a UNESCO World Heritage Site because of its incredible diversity of flora and fauna. The park’s Mount Kinabalu is a granite intrusion formed 15 million years ago and thrusted upward one million years ago from tectonic movements that continue to shape its landscape today. It contains a wide range of habitats including rich tropical lowland and hill rainforest to tropical mountain forest, sub-alpine forest, and scrub on the higher elevations.

Enjoy a full day exploring the various trails at the base of the park while birding. This park is a birdwatcher’s paradise with about 326 species recorded, representing over half the bird species in Borneo (18 are Bornean endemics). As you traverse the beautiful scenery, try spotting some of the endemics (found only in Borneo) which include the mountain black eye, the mountain blackbird, the Bornean treepie, the Kinabalu friendly warbler, the Kinabalu serpent eagle, the Bornean mountain whistler, the Everett’s thrush, and the whitehead’s trio.
