The longest road in Thailand, both it and its many adjoining 'sois' (sub-streets) are poor on traditional tourist attractions but rich in of-the-minute shopping, eating and nightlife. The many fashionable restaurants, bars, air-conditioned malls, luxury hotels and hip clubs give the area a distinctly modern, cosmopolitan flavour.

Some of the city's most sinful spots, red-light districts Nana Plaza (Soi 4) and Soi Cowboy (off Soi 23) are also found here. And little, stress-busting pockets of calm can be found in the sweet cafes, atmospheric restaurants and lush day spas that hide down many of its sois. Making exploring its staggering length incredibly easy is the Skytrain (BTS) that runs through most of its downtown stretch.
