You can travel by air, land or seas via Bintulu.
Uniquely enough, nowhere in the country could you step out of the plane and walk right into the main street. But that's Bintulu, the airport was only a doorstep away from town and this fact was listed in the Guiness Book of World Records as the town sited nearest to an airport. But that is history now as the new airport is quite a distance from town now.
