Each province in Vietnam has its own major terminal, particularly in big towns and cities like Hanoi (My Dinh Bus station, Giap Bat coach station), Ho Chi Minh City (Mien Tay, Mien Dong); you can find buses probably every tourism location as well as other province in Vietnam. Typically, interprovincial buses tend to be top quality ones with great services, huge and comfortable chairs. All you have to do is to buy seats from registered ticket stands inside terminal, and soon after show it to your conductor regarding the bus. There's no restriction for size of baggage.
The price is dependent upon the exact distance associated with the route and particular seats opted for. Tourists can ask their travel companies to purchase admission ahead of time, and sometimes even guide violation via phone or net independently. Observe that Internet scheduling coach solution is not very preferred, only relevant to a couple large coach companies like Hoang longer. If you depart from minor provinces and there is no direct route to your plan locations, it is advisable to catch a bus to major locations (Hanoi for northern provinces, Hue or Da Nang for main area, and Ho Chi Minh City for south provinces) and then change the coach there.
In Hanoi, Ho Chi Minh City plus some significant tourism destinations, there is certainly community bus solution for people both neighborhood and foreigners. Those buses in addition departure from major terminals before going to various other streets. In other provinces, we also have buses operate by private companies. Passengers can get coach at bus stops scattering all over province and buy admission directly from conductor. Although the solution is quite inexpensive (under VND 10000), the service is not very large (you may need to stand in the event that coach is too crowded, the coach may not have air conditioning unit, or perhaps the conductor cannot speak English). However, neighborhood bus is one interesting solution to comprehend much more or socialize with local people.
