Transportation is one of some amazing things in Viet Nam. Here is some information about how to travel around Vietnam after you apply Vietnam visa by car, taxi, flight and moreover which you may need to know when come to Vietnam. Each type has its own excitement, and convenience in every region. Please choose a star vehicle for the more interesting trip.

Cyclos (Xich Lo)
Vietnam is well-known elsewhere as rickshaws or pedicabs, the cyclo's designed slightly varies according to what part of the country on is in. This cheap and environmentally friendly mode of transport is steadily dying out, but it is still founded in Vietnam's main cities. These are a fixture in all major and minor cities in Vietnam. Cyclos should be booked through your tour company or through the doorman or concierge of your hotel. Here is an ancient culture preserved until todays.
Today, some weddings in Hanoi still use cyclos which shows originality and tradition. There are many cyclos around Hoan Kiem Lake. It's excellent to visit around Hanoi's Old Quarter. Any trip to Vietnam without riding a cyclo is a trip deprived. Cyclos's fares are between 15,000d and 30,0000d for a short ride, between 20,000d and 40,000d for a longer or night ride, or around 50,000d per hour. Remember, you need to bargain to get a good fare. When going around late at night, you should take a metered taxi instead of Cyclos. This term literally means to "hug the motorbike". Realy, "Xe Om" is a transportation service that transports people and goods (often carry people and goods mainly baggage attached) in the form of motorcycle. Xe Om drivers (motorbike taxis) peruse the streets in the cities and in the countryside looking for fares. This is the mobile medium, faster and more convenient transportation than the bus. And it is also the most popular transportation in Vietnam so it is easy for you to find "Xe Om". How to hail a Xe Om: extend your arm and hand directly outward; flutter your wrist as if waving goodbye to someone… this will hail the first available Xe Om. . . or perhaps even a mob of them. Because Vietnam's traffic is complex and a bit dangerous for stranger, this is an interesting experience of trip to Vietnam. Fares are comparable with those for a cyclo, but negotiate the price beforehand. 

Perhaps the best taxi service in the world exists in Hanoi and Ho Chi Minh City; the taxis are new, reliable and economical. Always take a metered taxi. Using Taxis is probably the safest way, special when you travel around at night. Vietnam has many taxi companies. They run continuously through the streets in Hanoi and Ho Chi Minh. You can call them whenever you need. But they are only popular in big cities such as: Hanoi, Ho Chi Minh City, Da Nang, Ha Long… and less popular in small cities. If you visit the countryside or mountains, it is difficult for you to find them. I recommend you should use "Xe Om" Average tariffs are about 10,000d to 15,000d per kilometre, some are cheaper with 6.000-7.000dFew travellers deal with city buses due to communication issues and the cheapness of taxis, cyclos and xe om. That said, the bus systems in Hanoi and HCMC are not impossible to negotiate – get your hands on a bus map. The price is fixed and show in the bus. It's safe when you go there. More complicated. If you buy a ticket from the point of departure (at the bus station), then the price is fixed and very reasonable. However, should you board a bus along the way, there's a good chance the driver or conductor will overcharge. In remote areas drivers may ask for four, or even 10, times what the locals pay. Local bus prices should be fixed and displayed by the door, but foreigners are sometimes overcharged on routes such as Danang–Hoi An. Late model Toyota, Honda, GM, Ford, Mercedes Benz cars and vans are available for hire (with driver) through your tour company or your hotel. Self-driven rental cars are not recommended for the rules of the road are entirely different with some countries… 

Generally, you use this transportation, you must book tour at tour company. But they have some disadvantages when you visit the mountains, caves. It's wonderful for you to visit ancient places: Hanoi's Old Quarter, Hoi An ancient… by bicycles. You will slowly feel the beauty of them. Travel by bicycles through the ancient streets you will see the beauty of slow life, your soul will be mixed with nature. A sense is peace of mind! this will be holded in your hear with unforgettable memories. Motorbikes are the major transportations in Vietnam. You can only count a few cars or vans in the highway. Motorbikes are available for rent but are strongly not recommended if you do not familiar with traffic here. I think it is suitable for anyone who likes adventure and discovery. Generally, you shouldn't use them because you are strange, you don't know much about the roads in Vietnam. Moreover, Vietnam's traffic is very complex. They are well worthy of watching for their amazing feats. A terrific book "Bikes of Burden" by Hans Kemp displays Vietnamese motorbike ingenuity at its very best (dulichso.com). Vietnam railway is developing, but it is still a level of developing country and not to expect any qualities. However, it is still functioning, it is cheap, easy and safe way to travel around the country. If you can give up a bit your comfort, it can be a cheap way to travel. One positive point is that you can have power supplied on the train where you can charge your mobile phone, camera etc. Its available in Ha Noi, Ho Chi Minh City (SaiGon), Mekong Delta. There are some options to use boats on the rivers in Hanoi like: Hong River, Tay River. Specially, its more developed in Ho Chi Minh City. They have a number of Saigon River day cruise and night cruise available for all types of budgets. The Day cruise usually goes around the Saigon River and to other parts of the South like in the Cu Chi Tunnels or the Mekong Delta or to then famous beach town of Vung Tau (which is a two-hour boat ride away via a fast catamaran). The Saigon River is the life blood of Saigon and that is why Saigon is a major Port Area for goods since the 17th century as the City was built at the Saigon River. Most people do the Saigon River Dinner Cruise which is a 2-hour dinner and cruising along the Saigon River and the ferry terminal is just beside the end of Nguyen Hue Street
