The starting point of most trips up the Rejang River is Sibu. Sarawak's second largest city is well connected by road, air and even boats with other Sarawak cities. See Sibu's Get In section for details.
However, there are several other less used ways of getting to other parts of the Rejang River hinterland.
Belaga can also be accessed via logging road from Tubau which in turn to connected to Bintulu by road and also by boat along the Kemena River. You can try and pay for a seat on the four-wheel drives and landcruisers which travel along the roads. There are no more flights to Belaga and travellers are no longer able to do the boat-plane combination to cover the Rejang River.
From Tubau, roads also go to the Sungai Asap resettlement village where the Kayan and Kenyah people who used to live in the area affected by the construction of the Bakun Dam have been relocated. Vans and other vehicles may take passengers for a fare from Bintulu to Sungai Asap. The road beyond Sungai Asap continues to the Bakun Dam construction site.
