The easiest way for tourists to get around are the Aizu Loop Buses which connect Aizu-Wakamatsu Station with all of the city's sites of interest. The loop buses operate from 8:00 to 17:30 and depart every 30 minutes. Buses running in the counter-clockwise direction are called Haikarasan while buses running in the opposite direction are called Akabe. The fare is 210 yen per ride or 600 yen for a day pass for unlimited rides on one calendar day.
Aizu has also a network of regular city buses, although most tourists will not need to use them, as the loop buses are easier to use. Fares for regular buses are dependent on distance traveled.
