The Baram river system so dominates northern Sarawak that you could consider virtually all the interior here, excepting Limbang division, to be the Ulu Baram – practically every river, including the Melinau and Tutoh at Mulu, the Tinjar at Loagan Bunut and the Dapur and Kelapang at Bario, ends up flowing into the Baram. The Batang Baram itself, however, wends its way more or less constantly southeast from the town of Marudi, 80km from Miri, occasionally passing little confluence towns such as Long Lama and Long San, before approaching the border with Kalimantan. Here it swings east to peter out beyond Lio Matoh, 200km southeast of Miri. This Ulu Baram, due south of Mulu and southwest of the Kelabit Highlands, is definitely outback territory, rugged and lushly forested, though not spared the attention of the logging companies, whose roads penetrate even here. There are, of course, no specific sights; the reason you might venture here is to trek through virgin rainforest and stay in remote settlements as part of a homestay programme.
