Niah Caves

Niah Caves, Malaysia

The wet boardwalk leads through rainforest toward the bright west mouth of the Great Cave at Niah Caves as the sun sets.

Niah Caves is a vast limestone cavern in Sarawak's rainforest, where people sheltered for a very long time and rare cave paintings survive.

The place

Niah Caves sit inside Niah National Park, in the Miri Division of Sarawak, on the Malaysian side of Borneo. The caves open on the northern flank of Gunung Subis, a limestone hill that rises out of low rainforest, about 15 km inland from the South China Sea. The best-known entrance is the west mouth of the Great Cave. It lies around 50 m above sea level and measures about 150 m across and 75 m high, so large that first-time visitors often stop talking when they reach it.

The approach is part of the experience. A raised boardwalk crosses damp forest, passing roots, ferns, bracts of wild ginger and the grey walls of the hill itself. The air is humid and smells of earth, and the temperature drops noticeably as the cave mouth nears. Inside, the floor is uneven, the light fades quickly and the ceiling disappears into darkness. Bats and swiftlets live here in great numbers, and their droppings coat parts of the floor.

The park was founded in 1974 and the site is also tied to a UNESCO listing. It is an archaeological site as much as a natural one, which is why paths are fixed and some areas are fenced. Sarawak is thinly visited compared with the peninsula, so the caves are rarely crowded, though school groups and weekend visitors can fill the boardwalk. Expect heat, sweat, slippery planks and a lot of walking in the dark.

Its story

Niah Caves entered the written record through the Victorian naturalist's network in Borneo. Alfred Russel Wallace was staying with a mining engineer, Robert Coulson, who had travelled through northern Sarawak looking for ore and had noticed bones in several caves. Wallace's curiosity was caught, and in 1864 plans were made for a proper survey. The job passed through a few hands before Alfred Hart Everett took it on, eventually surveying 32 caves in three areas, among them the Niah and Subis district near Miri. Later research showed that the first published account of the Subis caves was actually written by William Maunder Crocker, not Everett as long believed.

The modern story begins in the 1950s with Tom Harrisson, curator of the Sarawak State Museum, who was hunting for traces of ancient people in the region. His first look at Niah turned up little obvious evidence. But he reasoned that a cave that was cool, dry and full of bats and swiftlets offered a ready supply of food, and that early people would have found it very attractive. That reasoning led to long excavations, and the cave has since become one of the key places for understanding early human life in Southeast Asia.

The wider Sarawak background is colonial. In 1841 James Brooke became Rajah of Sarawak, and his family ruled until the Japanese invasion of the Pacific War, after which the territory passed to the British crown.

What to see

Culture

Niah Caves belong to a state whose cultural life is shaped by the Iban, Bidayuh, Melanau and many other communities, and also by a long colonial and trading past. Around the caves, the human story is much older than any of them. Archaeologists have used the site to understand how early people lived by the forest, hunted, gathered and buried their dead, and the park is protected partly for that reason.

Local people have long gathered edible swiftlet nests from the cave walls and collected bat guano, and traders came to buy both. That economy still exists in places, with nest collectors working under licence and passing along ladders and poles that look improbable from the ground. Seeing it is a reminder that the caves are a workplace as well as an attraction.

Beyond the park, longhouses remain central to rural life in Sarawak. Visits are usually arranged through guides or local operators, and hospitality can include rice wine called tuak. Sarawak also keeps its own immigration rules, even for Malaysians from elsewhere in the country, which is a small sign of how distinct the state sees itself.

In the caves, stay on the marked boardwalk and paths, do not touch the painted walls or the old burial sites, and keep your voice low so you do not disturb the bats and the people who work there.

What to wear

Niah Caves lie in Sarawak, where traditional dress varies by community. Iban women have historically worn woven cloth such as the pua kumbu, a ceremonial textile with dyed patterns, along with silver ornaments and beaded jewellery for festivals. Men's ceremonial dress can include feather headdresses and woven jackets. Melanau, Bidayuh and Orang Ulu groups each have their own beadwork and patterns, usually worn at weddings, harvest festivals and cultural events rather than every day.

Everyday clothing around Miri and the park is simple and practical. People wear cotton T-shirts, light trousers or skirts, sandals and caps. Many Malay Muslim women wear a tudung headscarf with a loose blouse, and clothing in towns is generally modest rather than strict. Rubber boots are common among workers and guides.

For a visit, dress for heat, wet and rough ground. Light, quick-drying long trousers and a breathable shirt protect from insects, scratches and the sun. Closed shoes with good grip matter more than anything else, because the boardwalk is slippery after rain and the cave floor is uneven and sometimes coated with droppings. A cap or hat helps outside, a thin rain jacket is useful, and a head torch with spare batteries is essential. Shoulders and knees do not need covering inside the caves, but modest clothing is sensible in villages and longhouses.

What to eat

Plan it

Best time. March to August is generally the easier stretch, with fewer heavy downpours, although Sarawak is equatorial and rain can come at any time. The wetter months towards the end of the year make the boardwalk slick and the cave floor muddier. Check the current forecast before you go.

How long. 1–2

Getting there. Fly to Miri airport (MYY), which has connections from Kuala Lumpur, Kota Kinabalu and Singapore. From there, go by road to Niah National Park, then walk the boardwalk to the caves. Check the official park site for current access, transport and any permits.
