The highlands occupy the northernmost reaches of Sarawak's interior, pressed against the Indonesian border in the Miri Division. Three peaks dominate the skyline: Mount Murud at 2,423 meters, the highest point in Sarawak; Bukit Batu Buli at 2,082 meters; and the dramatic twin pinnacles of Bukit Batu Lawi at 2,046 meters. Between these mountains, the plateau unfolds as a broad, fertile basin that has been farmed for thousands of years. During the Last Glacial Maximum, temperatures here dropped significantly, reshaping the vegetation and leaving traces that researchers have recovered from ancient pollen cores. Today the climate remains noticeably cooler than the sweltering lowlands, with temperatures that can dip into the low teens at night, a rarity in equatorial Borneo. The cool air sharpens everything: the colors of the paddies, the edges of the mountains, the smoke curling from longhouse kitchens at dawn.

The Kelabit settlements scatter across the plateau in a pattern shaped by history and terrain. Bario Asal stands as the original longhouse, the one the others branched from. In the 1960s, resettlement created new villages: Ulung Palang, Arur Dalan, Pa'Ramapoh Atas and Bawah, Pa'Derung, Padang Pasir, and Kampung Baru. To the east lie Pa'Umor, Pa'Ukat, and Pa'Lungan; to the south, Long Dano, Pa'Dallih, and Remudu. The more distant villages of Long Lellang and Long Seridan sit at the plateau's margins. Thirteen communities in all, each centered on a longhouse that can stretch 75 meters in length, housing an entire village under one roof. Before contact with missionaries in the 1940s, the Kelabit were headhunters. The longhouse served practical purposes beyond shelter: defense, governance, and the kind of radical communal living where everyone's door opens onto the same corridor.

What distinguishes the Kelabit from most of Borneo's indigenous groups is their rice. While neighboring peoples practiced swidden agriculture, clearing and burning new plots in cycles, the Kelabit developed permanent wet-rice cultivation, flooding their paddies in a system more commonly associated with lowland Asian civilizations. Bario rice, grown at altitude in cool air and irrigated by mountain streams, is famous across Malaysia for its fragrance and delicate sweetness. The grain takes longer to mature at elevation, which concentrates its flavor. In 2011, the Malaysian agricultural company Ceria Group introduced mechanized farming to the region, a change that NPR documented as bringing rapid transformation to a place defined by slowness. The tension between efficiency and tradition is real: machines harvest in hours what once took weeks of communal labor, but the communal labor was never just about the rice. It was how the villages held together.

On October 3, 1973, something happened in Bario that the Kelabit still talk about. The community had been nominally Christian since the 1940s, when Australian missionary Charles Hudson Southwell of the Borneo Evangelical Mission made contact and conversions followed. But over the decades, the faith had become routine. Then the Bario Revival began. According to witnesses, the event was sudden and overwhelming, bringing waves of repentance, reconciliation, and what participants described as spiritual transformation. Feuds ended. Alcoholism receded. The revival spread from Bario into neighboring tribes and set off four additional waves over the following eleven years. More than fifty years later, the Borneo Evangelical Mission, known locally as Sidang Injil Borneo, is one of the largest evangelical denominations in Malaysia. The revival made Sarawak predominantly Christian, a striking contrast with the rest of the country.

Bario Airport is a gravel strip carved into the plateau, served by MASwings Twin Otters that carry eighteen passengers at a time. Flights from Miri take about an hour but are frequently cancelled due to weather, low cloud cover rolling in without warning across the mountain passes. When planes cannot land, the highlands revert to their natural state of isolation. The alternative is a trek through dense montane rainforest, a journey measured in days rather than hours. This remoteness is both the highlands' vulnerability and their preservation. Young Kelabit leave for education in Miri, Kuching, or Kuala Lumpur, and many do not return. The population in the highlands has been declining for decades. Yet the Bario Food Festival draws visitors each year to taste the rice, and trekkers come to walk the trails between longhouses, sleeping on the communal floors where the Kelabit have slept for four thousand years.
