Bangkok is an impossible city to navigate. Its layout, on top of a number of waterways, makes grid-like road construction impossible. People who travel by road find bottlenecks everywhere. The relatively new Skytrain not only helps commuters rise above the gridlock, it also offers some great views of the mix of modern, historic and cultural buildings that make up this exotic Southeast Asian metropolis.
Bangkok's water taxis provide a taste of the canals and the wide Chao Phraya River that punctuates the city's geography. More expensive tourist boats or long-tail charters are available, but you can take regular water taxis to see many of the same sights. These purpose-made boats are furnished with tarps that help protect passengers from the spray from the polluted canal waters.
