Kanchanaburi, which is located where the Khwae Noi and Khwae Yai rivers converge into the Mae Klong river, spans the northern banks of the river and is a popular spot for travelers, its location at the edge of a mountain range keeping it much cooler than the other provinces of central Thailand. The city has two major commercial districts: the downtown area consists of a grid of several streets with office buildings, shop fronts, and a shopping mall; and the riverfront area businesses are mostly located further west along River Kwai Road. Once a year a carnival comes to town and is set up in the area next to the bridge. At night there is a small pyrotechnics display that re-enacts the wartime bombing of the bridge.
