Flights to Kuching are the most straightforward way into SarawakThe main overland route into Sarawak is by bus from Kuala Belait in Brunei to Miri, though this involves a time-consuming ferry ride across the Belait River and often slow passage through border stations (and avoid the weekend log jams if at all possible; see "Travel details" for full travel details). A second crossing is via Sipitang in Sabah to Lawas, one of Sarawak's two northern divisions. The Lawas Express coach originates in Sabah's capital Kota Kinabalu, and will get you to Lawas before nightfall. From Lawas you can get onward travel by bus to the Brunei capital, or there are flights to Miri. More straightforward is the southern overland route, with daily buses leaving from Pontianak, the capital of Kalimantan, crossing from Entikong to Tebedu in southwest Sarawak, around 100km from Kuching.
There are daily boat services from Brunei to both Lawas and the other of Sarawak's northern divisions, Limbang. Note that Limbang is only connected to the rest of Sarawak by air.
Getting around
Boats, often the only mode of transport in the interior, nearly always run to a reliable timetable, and come in three main types: sea-going launches, which ply the busy stretch from Kuching to Sarikei, at the mouth of Batang Rajang; express boats, which shoot up and down the main rivers; and smaller longboats, which provide transport along the tributaries.
If you need to rent a longboat to get along more remote tributaries, note that this can be prohibitively expensive if you aren't travelling in a group. It's common to pay in excess of RM150 a day per person for a boat ride to visit distant longhouses as diesel goes up in price substantially the further you are away from a filling station. In addition, although the distances travelled from one longhouse to another are often not great (around 2–5km on average), travelling upstream against the current, in shallow waters (in the dry season) and through rapids, can be hard going, placing a major strain on outdoor motors and the craft's underbelly. You may have to get out of the boat and help pull it over the rocks.
In northern Sarawak, an essential way of getting around is by Twin Otter and Fokker planes, a service formerly run by MAS and now run by Fly Asian Xpress (FAX;
http://www.flyairasianxpress.com), a subsidiary of AirAsia, which seat around eighteen and fifty people respectively. These small aircraft service a great many remote communities, most significantly Bario and Ba Kelalan in the Kelabit Highlands, Marudi and Mulu National Park. It's best to book up to a month in advance for both legs of your journey, if your schedule permits, as the planes can fill up fast. The standard baggage allowance on these planes is only 10kg per person, with excess baggage, if room, charged at high rates.
