Vietnam makes an exotic travel destination that offers pretty much everything to everyone. Planning a trip in Vietnam is quiet simple and straight forward if you plan liberally for at least two weeks. You can either do it top down from Hanoi or Bottom up from Saigon allies HCMC, as the country stretches narrowly in north south direction. And depending on your preference you can choose what places you want to stop by along the way while you are traversing the country either by road or rail. Travelling by road is comfortable enough and is much preferred as trains are more expensive than the buses.
