Chaotic, but Interesting
It's definitely an adjustment to come from a Western country and attempt to navigate HCMC's traffic; it almost seems like even odds that one would do just as well while wearing a blindfold, as the motorbikes would probably just flow around the person like water. There's a lot going on in this city if you can brave that mess; there's also a lot of people trying to sell things, and getting in your face about it. Good luck if you give it a shot!
Insider Tip:There's a very cheap bus that goes from the airport almost directly to the backpacker area - much easier and hugely more affordable than the taxis! Just look for bus #152.
