By plane

Traveling by plane is convenient because it allows us to save time. A regular passenger airplane can travel 600 kilometers in just about an hour. Although air travel is fast, the waiting time before departure can be a problem. An airplane ticket could be expensive, too.

By car

Driving is not as fast as flying. It can take a driver about 17 hours to travel 600 kilometers. That’s too long for a drive. Although it is not as comfortable as going by air, driving can be a great experience on a long journey. You can stop by a place you like or even stay as long as you want to.

By train

Trains can be as convenient as planes. Although traveling by train is not as fast as traveling by airplane, a train can be reliable. Trains don’t often go through the city center, so they rarely get into traffic jams. Besides, trains usually go through beautiful countryside, so passengers can relax and enjoy themselves with a fantastic view.

By motorbike

Going by motorbike cannot be as comfortable as driving, but a motorbike can be as reliable as a car or even an airplane. A young Vietnamese man started to travel the world only on his motorbike. He visited 50 countries and returned to Vietnam in June 2017.
