Somerset Maugham called this Malaysian state a "terribly jungly place". For visitors, the character of its people is just as impenetrable. So Sholto Byrnes made the trip with a local...

The call from the mosque may be heard in its capital, Kuching, or above the roar of the waves in Miri, near the border with Brunei. Though Muslims are in a majority in other Malaysian states, here they are in a minority, as are the Malays themselves, outnumbered by both the Chinese and the indigenous Iban. Most are Christian, although the old animist traditions retain their hold, as do the shamans who harnessed nature's powers.

To the casual tourist, enchanted by the fireflies that land on deck during a mangrove cruise along Damai beach, north of Kuching, Sarawak may simply seem the perfect place to take an adventurous holiday. However, those accompanied by a Malaysian, as I was, are privy to other dimensions. In every place we went, our guides talked to Farah, my girlfriend, about spirits. These conversations were in Malay; they know that Westerners give little credence to such beliefs. But from these we gathered, for instance, that it would be unwise to stay in room 303 at the Holiday Inn at Damai Beach, as it already has a ghostly inhabitant.

The following night, as we sipped tuak (rice wine) in the Nanga Sumpa Longhouse at the end of a day travelling by longboat up the Batang Ai river, we learnt more. If the dogs howl at night, said the Tuai Rumah (headman), it means that they can see the spirits. The rest of our group sat nearby, watching the longhouse men take turns at the traditional dance inspired by the flight of the hornbill, the state bird of Sarawak. Perhaps just as well, they heard nothing of the spirits, who are not necessarily, but can be, malicious, as the headman did not speak English.

No such thoughts would have troubled them when we arrived in the late afternoon. The longhouse itself, built entirely of natural materials, was enough to take in. Home to 319 people, it has a central corridor, under which animals wander between the stilts. On one side of the corridor are the doors, behind which each family lives - Nanga Sumpa is a "30-door" longhouse - and on the other, each family's verandah. Baskets and carvings hang from the ceiling above pictures torn from magazines - the king and queen of Malaysia next to Westlife, and further along the wall a signed publicity photo of Miss Texas 1999, one Carissa Blair.

Outside, children play in the river, which at this point is close to its source. Clear and cooling, it has a fast current and is safe to swim in; there are no crocodiles this far up, and no snakes to be seen either. Nearby, before you reach the thicker primary rainforest, are hillsides and fields cleared to grow rubber trees, pineapple bushes, and tapioca and galangal plants. Further upstream, locals catch small, silvery fish with nets.

The accommodation may be primitive - mattresses on a raised wooden platform - but no resort can match the perfection of lying on your back and being swept downriver while towering rainforest frames a cloudless blue sky above. The traditional longhouses, however, are disappearing. Modern, concrete versions are springing up, and some of the tribesmen are moving away to the towns. The proud boast of one local - "We didn't join Malaysia, we formed Malaysia" - is hollow. While this is true - Malaysia was formed by the union of the Federation of Malaya, Sarawak, Sabah and (initially) Singapore in 1963 - the voice of Sarawak is not heard loudly in the highest councils, and there is a feeling that its natural resources are being exploited for the benefit of peninsular Malaysia. Sarawak, think many locals, is not getting its proper share. Certainly, insufficient effort is going towards helping the longhouse dwellers to preserve their traditional way of life.

At the eastern end of the state, two flights away from Kuching, the story is happier. The Gunung Mulu National Park, the largest park in Sarawak, contains the most extensive cave system in the world. The Royal Mulu Hotel, built on stilts in the style of a longhouse, is on the park's doorstep. A few minutes' drive away is the canopy walk, 100 feet above the ground. Consisting of a tiny walkway with ropes either side, it is not for the faint-hearted. From there you can look down and try to spot honey bears, civet cats and deer, or observe at eye level the stringy rotan (which is used for caning criminals) climb unfeasibly high by using its thorns to cling on to sturdier trees.

By late afternoon it is time to explore Lang cave. Formed by standing water over the course of four million years, it has a stunning collection of stalactites and stalagmites. Deer Cave, nearby, relies on its size to overawe the visitor. Big enough to fit St Paul's Cathedral five times over, it is also home to millions of bats which hang under its roof by day, then stream out in thin ribbons at dusk. If Peter Jackson ever needed a real location to film the cavernous dwarf halls of Moria, he could do no better than Deer Cave, whose eerie dimensions bring Tolkien immediately to mind.

Back in Miri, after indifferent food at the Royal Mulu, the comforts of the newly opened Marriott were welcome. Looking in at the restaurant before opening time, we asked if char kway teow (a Chinese Malaysian noodle dish) was on the menu. It wasn't, said Gabriel, the head chef, but he would see what he could do. Later on, our plates laden with chicken, beef, lamb, prawn and squid satay, a dish of some of the finest kway teow I have ever tasted appeared at our table.

Days later, back in Kuala Lumpur, I picked up a copy of Somerset Maugham's The Casuarina Tree. His short stories of lonely British colonial officers capture the difference of Sarawak, but are filtered through his Home Counties suspicion of "otherness". Then I chanced upon his description of an evening's entertainment in a longhouse. The Casuarina Tree may have been published nearly 80 years ago, but it was as though Maugham were writing about the dance we had just seen at Nanga Sumpa. Go swiftly before this centuries-old culture ceases to live and becomes instead an exhibit in a museum. Its magic still lingers, but will not for long.
