The only international airport is Brunei International Airport (BWN) on the outskirts of Bandar Seri Begawan. Royal Brunei Airlines flies direct to Kuala Lumpur, Singapore, Bangkok, Jakarta, Manila, Hong Kong, Dubai, and London. Budget carriers connect to the region as well, and flights from most Southeast Asian hubs take under three hours.
Overland entry from Malaysia is straightforward. From Miri in Sarawak, buses run to Bandar Seri Begawan in around two to three hours, crossing the Sungai Tujoh border. The journey is cheap — expect to pay around 50 to 70 Malaysian ringgit — and border formalities are quick for most nationalities. From Kota Kinabalu in Sabah, the Sipitang Express bus operates three days a week (Tuesday, Thursday, Saturday), departing early morning and taking most of the day, though you can also break the journey and cross via Labuan.
Via Labuan: ferries run from Kota Kinabalu to Labuan island (roughly three hours), and then from Labuan to Brunei (around two hours). Multiple departures daily in each direction, though schedules shift seasonally — confirm before you go. This route offers a scenic alternative to the long bus ride.
Note that Brunei sits in two separate chunks of territory, divided by a strip of Malaysia. Road travel between Bandar Seri Begawan and Bangar in the Temburong district requires a short transit through Malaysia or — more commonly — the daily speedboat service up the Brunei River.
Most nationalities do not need a visa for visits up to 30 or 90 days. US and Canadian citizens are visa-free for 90 days. EU and UK citizens get 30 days. Check with your nearest Brunei embassy if you are unsure. All visitors must complete an e-Arrival Card online before traveling (air, land, or sea entry).
