Our tour starts today in Kuching. The capital of Borneo's Sarawak region is a riverside city where culture, food and nature come together. It's the perfect jumping-off point to explore Borneo's wild side. For those arriving on time, our tour leader will meet you in the hotel reception at 6pm for a welcome meeting. There are no other activities planned today, so you're free to arrive at any time. If you'd like an airport transfer today, you'll need to arrive into Kuching International Airport (KCH), which is a 20-minute drive from the hotel. If you miss the welcome meeting, our tour leader will catch you up over breakfast on day 2. If your flight arrives earlier in the day, why not visit the waterfront for a bite to eat or drop by the fruit market to watch local life unfold.

Today we'll discover the history of Kuching on foot. We'll start our walking tour on India Street and follow a narrow passageway to discover a hidden Indian Mosque. Continuing on, we'll visit the Old Kuching Courthouse, the first Brooke-era administrative building, and The Pavillion, originally used as a medical headquarters. Our city tour then takes us to the Main Bazaar, one of the city's oldest streets, where we can see antiques and handicrafts and the 175-year-old temple, Tua Pek Kong Temple, a singular Chinese temple and its dominant dragon. Finally, we'll take to the water in a Sampan (a traditional boat) and retrace our steps downriver, watching the bustle of local life along the banks. From the river, we'll enjoy a 360 panoramic view of Kuching and its historical landmarks, set against a background of Malay Villages and distant mountains.

We'll set off early this morning to travel to Bako National Park. Our journey involved a 45-minute drive, followed by a 30-minute cruise along the coast. The oldest of Sarawak's national parks, Bako is the perfect introduction to the region's forests and wildlife. It's home to 275 rare proboscis monkeys, found only in Borneo, and we'll have the chance to spot them, as well as silvered langurs, bearded pigs and monitor lizards. Despite its small size, Bako contains varied terrain, from swamp forest to scrub-like padang vegetation, mangrove forest to dipterocarp forest and delicate cliff vegetation to sandy beaches. We'll head out on walking trails to explore the rainforest, walking past the dipterocarps and dense mangrove forests. Bako is also home to many bird species such as the rufous-backed kingfisher, stork-billed kingfisher, red-crowned barbet, white-bellied woodpecker and many more. During low tide, you can spot the mudskippers and blue-fiddler crabs coming out from their hideout for feeding on the beaches, too. After a simple lunch at the park café, we'll return to Kuching.

Today we fly to Mulu, our home for the next two nights. Depending on our arrival time, we have several optional activities to choose from: wander to the Tree Top Tower for views across the Mulu National Park, stroll along the boardwalk to Pukau Waterfall or walk on the Nature Heritage Trail. In the afternoon, we'll head to Mulu National Park Headquarters. Here, we'll take the elevated plank walk to Lang Cave, the longest cave passage in the world. We'll explore its magnificent stalactites and stalagmites before carrying on to the adjoining Deer Cave. Deer Cave is famous for its colony of thousands of free-tailed bats and at dusk, you can watch them emerge from their cave in formation to forage for insects in the rainforest. Our exploration doesn't stop after dark. Next, we'll head out for a night trek through the jungle. The way is dotted with luminescent fungi and blinking fireflies giving us the chance to see creatures not visible in daylight.

This morning, we'll have breakfast accompanied by a jungle chorus before taking a short boat trip up the Melanau River to see two more of Mulu's caves - Wind Cave and Clearwater Cave. These two form part of the Sarawak Chamber, the largest connected cave system in the world. If water levels are low, we'll reach the caves on foot along a short trail. We'll explore the King's Room in Wind Cave before moving on to Clearwater Cave via plank walkways built on the sides of the limestone cliffs and a set of steep steps carved into the side of the hill. Once inside, we'll take some time to admire the limestone formations. Later today, we'll return to Mulu National Park Headquarters and take to the treetops on a canopy walkway. The rest of the afternoon is free - you might like to head out on one of the self-guided walking trails to explore more of the national park.

This morning we bid farewell to our Sarawak tour leader and take a short flight to Kota Kinabalu (KK as it is affectionately known by the locals). Here we'll meet our Sabah tour leader who will accompany us until the end of the tour. The small capital is a cultural tapestry - its inhabitants are a mix of Chinese, Indonesian, Filipino, Indian and of course Malay. This blend of influences makes KK a foodie's dream, with fusion restaurants popping up all over town and street-food stalls serving classics like Nasi Goreng (fried rice with spices) and satay alongside curries and kimchi. We'll land at lunchtime and the rest of the day is free to explore the city's vibrant foodie scene

Today, we'll head out to explore the sights of KK. Having been bombed extensively during World War II, Kota Kinabalu has little of its historic architecture left, however, you can spot glimpses of it amongst the ramshackle markets and mosques. First, we'll visit Tun Mustapha Tower - the tallest building in KK encapsulates the city's new and modern feel. Next, we'll get a feel for the cultural diversity of the city with a visit to the beautiful Chinese temple of Puh Toh Tze, followed by the impressive State Mosque. This much-photographed mosque features intricate examples of Islamic architecture with gold motifs decorating its grand dome. We'll finish our tour at Signal Hill, where you can get a view of the city skyline from the observation platform. This afternoon is free for you to explore more solo, perhaps dropping by the local handicraft market. Alternatively, there's an optional trip to the nearby Mari Mari village, a traditional settlement that celebrates and preserves the indigenous tribes of Borneo.

After breakfast, we'll drive to the Crocker Mountain Range (a two-and-a-half-hour journey), home to the highest mountain in Southeast Asia - Mount Kinabalu. Our destination is the small village of Tanak Nabalu where we'll share lunch with the local villagers. The people here are from the ethnic Dusan tribe, most of which now offer their services as guides and porters up to Mount Kinabalu's summit. We'll spend time learning about their ancient culture and customs over a hearty lunch of Hinava. Similar to the Peruvian dish ceviche, Hinava is a raw fish dish which originates from Sabah's Kadazan Dusun tribes. Mackerel is the traditional fish used in Sabah - it's marinated in lime and served with red chilli, ginger, shallots, Bambangan seeds, and prawns. After lunch, we'll walk through the Botanical Gardens to see exotic species of flora such as slipper orchids, a variety of pitcher plants, yellow rhododendrons and much more. En route, we'll stop at the World War Two Memorial Park, which commemorates the thousands of Allied forces, including British and Australian, that lost their lives at the hands of the Japanese empire. Finally, we'll drive on to the town of Kundasang, our rest stop for the night.

This morning, we'll travel east and visit the Poring Hot Springs, an incredible collection of man-made geothermal pools dotted throughout the forest. Here, we can take a dip in the natural mineral-rich waters and spot monkeys and birds on the canopy walk that traverses the springs. There will also be an option to visit an Orchid Conservation Centre. Afterwards, we'll continue to a Rafflesia farm - known as the 'corpse flower' due to its strong smell, it's possibly the largest existing flower. Then, we'll continue our drive to Sepilok (a four-hour journey) arriving in the late afternoon.

We have a day full of wildlife ahead of us today. This morning, we set off on foot to the Sun Bear Conservation Centre. Sun bears are the smallest bears and their survival has been threatened by decades of ongoing deforestation. In the wild, they play a key role in keeping the forest healthy. To conservation centre cares for orphaned and confiscated bears, aiming to rehabilitate them and return them to their natural habitat. We'll continue our walk to Sepilok Orang-utan Sanctuary. A highlight for many of Borneo's visitors, Sepilok is home to the largest of the three orang-utan rehabilitation centres in the world. Covering over 4,000 hectares of forest, the centre was established in 1964 to rehabilitate captured, injured or abandoned apes. So far about 100 'wild men of the forest' have been brought to the centre, and there has been a remarkable success rate with up to 75% having returned to the jungle. The animals are taught how to survive in their natural habitat. We'll visit the centre in time for feeding when, along with the resident apes, females who normally live in the jungle, come to supplement their diet after the birth of their young. After lunch, we'll drive to Sukau, located along Sabah's longest river, the Kinabatangan. After some time to rest, we'll take to the water for our first river cruise, hoping to spot some of the endemic wildlife dotted among Sukau's myriad waterways. For those feeling energetic, tonight there'll be a night walk in the jungle with the chance to spot nocturnal animals like the civet cat, tarsier, and slow loris as well as owls, frogs and a variety of insects.

Waking to the distant calls of gibbons and hornbills, we'll have an early breakfast before joining a morning river cruise to Kelenanap Oxbow Lake. The Kinabatangan River area is home to an incredible array of wildlife - a total of 10 primate species including proboscis monkeys, langur monkeys, gibbons and macaques are all common here. With some luck, we might even spot an orangutan in the wild! The area is also known for pygmy elephants, Malay sun bears, clouded leopards and crocodiles. Birdlife is just as prolific, with all eight species of hornbill present, not to mention kingfishers, ospreys, storks and eagles. We have another river cruise this afternoon to spot more of Borneo's varied wildlife with the help of our expert guide. After dinner this evening, we'll also have an optional night cruise. This is an excellent opportunity to see the water lit up by fluorescent light, with the chance to see the shine of a pair of eyes staring back at us.

We head deeper into the rainforest today on our drive to the Reserve of Tabin (a three-and-a-half-hour drive). On route, we'll see many reminders of man's interference with nature. Much of the route to the conservation area has been deforested and replaced with vast swathes of palm oil plantations. Malaysian Borneo and Indonesia account for over 90% of the world's production of palm oil, and the drive today gives us first-hand experience of the problem it causes by displacing endemic and endangered wildlife and flora. Our tour leader will add some extra insight into the palm oil industry, a complex issue that isn't pleasant to witness but is a reality in modern-day Borneo. Fortunately, the Tabin Wildlife Reserve has long been kept as a conservation area, meaning the rainforest here has remained entirely intact. The Tabin Wildlife Reserve was created in 1984 to preserve some of Sabah's most endangered species and, covering an area of some 122,000 hectares, it's the largest in Malaysia. Tabin is home to the Sunda Clouded Leopard and the Borneo Elephant, as well as seven of Sabah's primates and a huge array of bird species. In the afternoon we head out for our first walk, along the Elephant trail to the Lipad Mud Volcano. This small active volcano provides a mineral salt lick and thus attracts a multitude of wildlife which we hope to spot. A variety of animal footprints are usually visible across the mud, and the adventurous can try out the effects of the mud which is said to be excellent for skin care. Our accommodation for the next two nights is the Tabin Wildlife Resort, a charming collection of wooden chalets built on stilts that look out over the river and surrounding hills. The chalets are comfortably appointed with en-suite facilities and a ceiling fan, and the resort also has a restaurant and bar.

We rise early this morning amongst the birdsong and gibbon calls to travel to the core of the reserve, climbing the observation tower to discover some of Tabin's near 300 species of birds. Here, we hope to spot species such as the Bronzed Drongo, Blue-crowned Hanging Parrot and Purple-throated Sunbird, to name but a few. We'll move on to the Orang-utan Release Centre to learn about the important work the centre plays in the final step of releasing rehabilitated Orang-utans back into the wild. From here, we'll continue on foot, through the lush steamy rainforest to Lipad Waterfall, where it's possible to take a dip in the natural pools and brave a shower under the falls. In the afternoon, you're free to relax in the natural surroundings, or perhaps try out the Tabin Rainforest Foot Soak - a mixture comprised of a natural blend of local herbs to ease those weary feet. After dinner, there will be the option to head out on a night walk. Keep an ear and eye out for some of the nocturnal wildlife found near the resort.

This morning, we have our final chance to spot some of Tabin's wildlife on a nature walk. At lunchtime, we'll drive to the bustling town of Sandakan.

Our trip ends after breakfast at our hotel in Sandakan. There are no activities planned today, so you're free to depart from Sandakan at any time. If your flight is departing later in the day, luggage storage facilities are available at our hotel. If you'd like an airport transfer today, you'll need to depart from Sandakan Airport (SDK), which is a 20-minute drive from the hotel.
