Thailand's capital city and by far the largest city in the country, Bangkok, is a buzzing cosmopolis of high rise buildings, magnificent palaces, ancient temples, glittering nightclubs, bustling markets and streets lined with vendors hawking souvenirs and tantalizing foods. While the city is sometimes described as a concrete jungle jam-packed with noisy traffic and air pollution, Bangkok is not without its natural beauty that is seen in its scenic canals, green spaces and flowering tropical plants.
