Hey everyone! I just landed in Brunei and I'm trying to figure out how to get to Kuala Belait. Google Maps says it's like a 2-hour drive, but I don't have a car and I'm not sure about buses. I saw something about a bus from the airport to Seria, but then what? Is there a direct bus or do I need to take a taxi the whole way? Also, are there any shared vans or something? I'm a bit confused and kinda stressed because I have a hostel booked in KB. Any tips would be awesome! Also, is it true that the roads are nice and smooth? I heard that from a friend. Thanks a ton!
