From Nha Trang, travelers who started in Hanoi and are going west have three main choices. You can continue on the train directly into Saigon, or take a bus to a smaller beach town call Mui Ne, or take a bus up into the Central Highlands to the town of Dalat, which is what I did. The bus ride took about 4.5 hours, including two long and mostly pointless rest stops. In a country like this I expected bus drivers to behave like amphetamine-crazed long-haul truckers, but it seems that they all stop for a long break about every 90 minutes.
