Borneo

Borneo, Indonesia

The granite summit of Mount Kinabalu glows amber at sunset above dark forest, with pitcher plants and a stone trail in the foreground.

Borneo is an equator-crossing rainforest island where orangutans, river journeys, coral walls and ancient caves sit within reach of each other.

The place

Borneo sits astride the equator in Maritime Southeast Asia, with Java to the south, Sulawesi to the east and Sumatra to the west. Three countries share it. Most of the land is Indonesian, where the island is called Kalimantan and divided into five provinces. The northern part belongs to the Malaysian states of Sabah and Sarawak, and the small state of Brunei occupies a stretch of the north-western coast. About 18.6 million people live here, and the surprise for many first-time visitors is how much of that life runs along rivers and the coast, with the interior far less settled. The island ranks third among the world's islands by area, so distances are real: a journey from one end to the other is a matter of flights, long river trips and rough roads, not an afternoon's drive. Geology and history explain the wildlife. Borneo was once joined to the Asian mainland and was cut off when the seas rose after the last ice age, leaving forests that evolved in isolation. The result is a mix of lowland rainforest, peat swamp, mountain slopes and lakes, with many species found nowhere else. The highest ground rises to 4,095 m. Hundreds of Indigenous communities, many grouped under the wide label Dayak, live across this landscape alongside Malay, Chinese, Banjar and other communities, and each country has its own mood, food and pace.

Its story

Borneo has been lived in for a very long time, and its caves are the best witnesses. Excavations at Niah in Sarawak, and in valleys near Lahad Datu and Kunak in Sabah, have turned up stone tools and human remains from tens of thousands of years ago. In the limestone of East Kalimantan, a cave called Lubang Jeriji Saléh holds a painting of an animal that researchers reported in 2018 as more than 40,000 years old, placing it among the earliest known figurative art. Later, the island plugged into sea trade. Chinese, Indian and Japanese records describe western coastal ports operating by the first millennium of the common era, shipping out gold, camphor, hornbill ivory, rattan, beeswax, bird's nests, spices and scented woods. Indian writers called the island the Land of Gold and the Camphor Island, while Javanese sources used a name meaning Diamond Island. Power then gathered on the coasts. The Majapahit of Java, the Sultanate of Brunei and the Sultanate of Sulu all held influence at various times, while the interior stayed in the hands of many local communities rather than a single ruler. Britain, the Netherlands and Japan each controlled parts of the island in later centuries. After decolonisation, Borneo settled into the three-way division that exists today, with Indonesia holding about 73 per cent of the land.

What to see

Culture

Borneo is a patchwork of cultures rather than a single one. In the interior, Dayak communities such as the Iban, Kenyah, Kayan and Dayak Ngaju have traditionally lived in longhouses, shared buildings where many families live under one roof along a long communal veranda. Rice farming, river fishing and forest foraging shaped their calendars, and harvest festivals still bring people home from towns and cities. Carved wood, beadwork, tattoos and woven cloth carry family and community identity. Along the coasts, Malay and Banjar communities have long followed Islam, and Brunei is a sultanate where Malay royal customs remain central to public life. Chinese communities, concentrated in towns such as Kuching and Pontianak, add temples, kopitiam coffee shops and festival calendars. Christianity is widespread among many Indigenous groups in Sarawak and Sabah, so Sunday is quiet in some villages. Logging, plantations and mining have changed the forest, and conversations about land rights and conservation are part of everyday life, so visitors will meet strong opinions. Guides from local communities are often the best route into this, both for the explanations they offer and because the money stays nearby. Ask the headman or your guide before photographing people or ceremonies, and when invited into a longhouse, accept the offered seat, remove your shoes at the door and bring a small gift for the community.

What to wear

Fashion in Borneo reflects its mix of peoples. Traditionally, many Dayak groups made cloth from cotton, bark or plant fibre, and beadwork, feathers and carved ornaments marked rank and occasion. The Iban of Sarawak are known for ceremonial woven textiles, usually patterned with dyed thread, which are worn or displayed at festivals, weddings and rites of passage. In Brunei and among coastal Malay communities, silk or cotton songket woven with metallic thread is worn for weddings and formal events, along with baju kurung and other Malay dress. Banjarmasin is associated with sasirangan, a stitched and dyed cloth. Everyday clothing now is modern and practical: T-shirts, jeans and light cotton shirts in the cities, headscarves for many Muslim women, and rubber boots for farmers and boatmen. Traditional dress comes out for harvest festivals, weddings and cultural performances. Visitors should dress for heat, humidity and sudden rain. Light, quick-drying long sleeves and trousers protect against sun, insects and leeches on forest trails. Sturdy shoes with grip suit wet boardwalks and muddy paths, and sandals are useful for boats. A thin rain jacket is better than an umbrella. For mosques, temples and village visits, cover shoulders and knees, and women may need a scarf for mosques. Swimwear belongs at the beach or on dive boats, not in towns.

What to eat

Plan it

Best time. Roughly March to September is usually the easier stretch, with less rain for river trips, forest walks and diving, though weather differs between coasts and the equatorial heat and humidity are constant. Rain is heavier in many areas from about November to February, when roads and rivers can disrupt plans.

How long. 7–10

Getting there. Main gateways are Kota Kinabalu and Kuching in Malaysia, Brunei International Airport, and Balikpapan, Pontianak and Banjarmasin in Indonesia. From there, the last leg is often a domestic flight, a long road transfer or a boat, so check the schedule for your route.
