Taxis in Ho Chi Minh City are both inexpensive and easily available. Stand on any street corner to flag a taxi and it won't take you long to jump into one. They are generally very convinient, though a few bogus ones do operate. The two biggest companies here are Vinasun and Mai Linh, if you stick to using those two, you won't go far wrong: the cars are usually clean and repaired, drivers are polite, well groomed, and sometimes can even start teaching you some Vietnamese phrases while on the way to your destination. It is rare that any journey within the city amounts to more than USD5. A way from the airport to the city centre costs around USD8.
