The Skytrain and metro networks are a great way to beat the Bangkok traffic. The downside is that both networks are limited in range and don’t cover all parts of the city. If you are going to or from Bangkok Suvarnabhumi airport consider using the airport rail link. It’s ultra-clean, quick and reliable but depending on where you are travelling to or from within the city it can still be less than ideal. In many cases the most convenient option is to take a taxi, especially if you are carrying heavy luggage or you are not close to a Skytrain or metro station.
Are the roads in Bangkok always congested?
Like any other major city around the world there are commercial areas and thoroughfares which are going to be busy at most times of the day, but it would also be misleading to say that the roads in Bangkok are permanently congested with traffic 24-hours a day, 7 days a week. Just to show you the other side of the coin, I took the photo below on a midweek morning in the Dusit area of Bangkok with barely a car in sight.
