Iowa 80 is the largest truck stop in the world. It sits just outside of Walcott, Iowa, and has all the trappings of a small city. There are eight restaurants on site, a barber shop, a dentist, a movie theater, a chiropractor, and even a pet wash center. With over 900 parking spots, there is plenty of space to park your car, truck, or RV and rest for a while. Even better, many of the facilities are open 24 hours, so you can fuel up, eat, and take a break no matter what time you pass through.
