Six days in Brunei was enough and so I set off for Sarawak. One of the reasons I stayed so long was that I wanted to do a trek to Gunung Mulu national park, just outside the Bruneian border and accessible from BSB. It is famous for housing one of the largest caves in the world which is home to a population of several million bats as well as some magnificent primary rainforest and karst terrain. To be able to afford the tour though I had to find other people with whom to split the costs of transport, guides and porters, but unfortunately I had no luck. Such is the way when travelling solo: sometimes it is not possible to do certain activities because you need a group of people and they just aren't available. Instead I had to make do with the caves at Batu Niah, also in Sarawak, but only a dozen kilometres from the main highway instead of requiring several days' hike (or a trip by plane). The main cave there is also staggeringly huge and is home to several species of bats and swiftlets, whose droppings, like in caves throughout the region, carpet the floor and give it a characteristic, overpowering odour. What perhaps makes the caves at Niah special are that they have been home to humans for some 40,000 years, with some of the oldest archaeological finds in all of southeast Asia. And they have been continually used for that entire time up to the present day, where local tribes collect swiftlet nests. Although it's not the season for collection the bamboo scaffolds used by the collectors are still up and extend vertiginously 50m or more up to the roof of the cave, seemingly held aloft by a single, narrow pole, somehow defying the laws of gravity.
