So many people have asked me about Vietnam. So often already I explained where they should go to, what they absolutely had to see and how to travel from city to city. It seems to me as if more and more people want to discover this country. It is definitely worth going there.
Here is therefore a little introduction to the main places to see.
You can start from two locations, either Hanoi, Vietnam’s capital city, or Saigon (Ho Chi Minh City), Vietnam’s economic heart. Last year we have started from Hanoi. Hanoi is a cute city, with some famous lakes and sites to visit. You’ll see that Hanoi is totally different from Saigon. Both cities are busy, you’ll have troubles crossing streets and you’ll wonder how they manage not to have accidents with their motorcycles (they actually do of course, but it is amazing to see their driving skills).
You need three days for Hanoi, it will enable you to see the necessary things, such as the Mausoleum, Hoa Kiem and to attend a water puppet show. From Hanoi you can do trips to the Ha Long bay and Sapa. I haven’t been to Sapa but heard that it is extremely beautiful. I have been to Ha Long and it is a must see. The best is to rent a boat (your hotel will organize that for you, or you take organized tours with famous travel agencies such as Sinh Café) and ship through the rocks. If you’re lucky you will witness a breathtaking sunset.

From there we have taken the boat to Cat Ba Island. If you like it remote it is the place to go to. The island has a big National Park, but you need to pay a guide to hike there. We just rented bikes and drove through the village and along the coast. That’s a lot of fun already. But don’t spend more than two nights here, you’ll get bored quickly, except if you plan on paying for the guide and the National Park.
Our next stop was Haiphong but personally I was quite disappointed. The city has few things to offer. Walk around at night, walk through the markets, that’s all you can do. The beach is unspectacular. You can skip Haiphong without feeling guilty. 
We returned to Hanoi in order to take the night train to Hue, the emperor’s capital city. You have the choice between two trains. One leaving at around noon and the other one leaving in the evening. I suggest that you take the one leaving at noon. Why? Because you’ll see parts of the landscape. I am not saying that the landscape is so amazing that you should not miss it, but it is still nice to see the rural areas. You’ll also see that the train passes through the streets, it passes so closely to the buildings, that you have the impression driving through the people’s shops and homes. If you leave at noon you’ll arrive in Hue at around 1am.

Hue is a fantastic city. You witness the former might of the Vietnamese emperors. The best thing to do is to rent a bicycle and ride from site to site. You can leave the bikes at the guarded parking areas and visit the pagodas and Forbidden City. For the tombs you better rent a motorcycle because they are a little bit out of Hue. You might get lost a couple of times, because the maps are not very precise but that’s part of the adventure. Don’t get desperate if it is raining, we have had lots of fun driving in the rain and through the enormous puddles.

If the weather is good you can go from Hue to Danang and to the nearby National Park. But we were unlucky, so we continued to Hoi An. Hoi An is a small picturesque village, famous for its silk. I think that you don’t need to spend too much time here but you definitely should arrange for a trip to My Son (an old grass-grown Hindu village). You can rent a motorcycle and drive there on your own or you can go there by bus with other tourists. To be honest, going there on your own is not so easy (the map was not precise enough) but it is a lot of fun. It was especially amazing to stop and walk through the fields and take pictures from the numerous water buffaloes. They are everywhere, you just need to stop and take your camera.

From Hoi An you’ll take the night bus to Nha Trang. This city is famous for its beaches; you can spend there a couple of days, relax and enjoy the time.

Then you can take the bus to Dalat. Dalat is not that far, on the map it looks pretty close but in reality it is quite a long drive. This is due to the fact that Dalat is way up in the mountains. It used to be the French’s favorite vacation place during the colonization. Therefore you can witness French architecture. Rent a motorcycle and drive through the mountains, visit the coffee plantations and the villages around. Personally, I think that Dalat is one of the absolute greatest places in Vietnam.

Dalat-Saigon by bus or plane, you will enter into the pulse of Vietnam. Here you can feel the dynamism, the speed, the desire to achieve something. Saigon is a modern city, full of bars, clubs and cafés. There aren’t many things to see here, you’ll take a room in Bui Vien street and enjoy the night life. You can do day trips to the Cu Chi tunnels or to the Mekong Delta. The latter one is a must.
If you want to spend more time at the sea, you can drive to Vung Tau or Mui Ne.
To finish your visit, take the plane to Phu Quoc and enjoy.
