Before you visit a country, make it mandatory to look at a spread of its pictures. Since you are traveling to an unknown place, these photos will give you a clear idea about the country and its customs. Never experiment on going to a country without knowing about it correctly, as it can land you in a lot of troubles. Also, when you look at the images, you will understand if the place is worth a visit or not. Especially for a destination like Vietnam, it will help you distinguish one state from the other, giving you a clear picture of what a state has to offer in the country.
The pictures will also give you an idea about the beautiful places you will come across in Vietnam and even lets you get an idea of the unexplored areas that you might like. It is ultimately your decision as to what places you want to visit in Vietnam, and these pictures will give you a clear perspective on it. Nevertheless, images can never do justice to the beauty of Vietnam. These photos will only serve as a trailer for you to build up your expectations for the final movie you will see after reaching the destination.
