Don't expect much tasteful and stunning architecture you would normally find in Southeast Asia. Most buildings are just plain and box-shaped.
After visiting the Brunei Museum, walk along the road toward BSB to visit two tombs: the first is the Tomb of Sharif Ali, the third sultan of Brunei. The green sign by the road is written entirely in Arabic lettering. Further down the road is the Tomb of Sultan Bolkiah, the fifth sultan of Brunei. Both tombs are in easy walking distance from the Museum. On your walk you may see some pitcher plants by the side of the road.
See the main Brunei article for entry formalities.
Brunei International Airport [1] is the main airport in Brunei. See Brunei | Get in for details of flight connections. Getting there/away: A taxi from the airport to Bandar Seri Begawan takes 20 minutes and costs around B$25. A covered walk down to the end of the car park away from the Terminal (turn right when exiting from Arrivals) leads to a bus stop for Purple buses to the city centre (B$1).
All main roads in Brunei (save for those in isolated Temburong District) lead to Bandar Seri Begawan. The main road into/out of Bandar connects to the coastal road to/from the Sarawak border via Tutong, Seria and Kuala Belait. Other main roads lead to Muara and Kuala Lurah where there is a border crossing into the Limbang division of Sarawak. Take this road if you are driving to Temburong but you will have to go through two sets of immigration checkpoints - at Kuala Lurah (Tedungan on the Sarawak side) and Puni (Pandaruan on the Sarawak side) - before you reach the district administrative centre, Bangar.
You can continue further from there all the way to Kota Kinabalu. See the Kota Kinabalu to Brunei in a day page for details. Caution: during several days of travelling by rented car it was not possible to find an accurate road map. Asking lokals for direction is however met with incredible friendliness and willingness to help, with people sometimes taking kilometers of detour just to be helpful.
The main bus terminal where all long-distance and local buses leave from and arrive is at Jalan Cator in the city centre. It occupies the ground level of a multistorey carpark.
