Sioux City sits where Iowa, Nebraska, and South Dakota meet along the Missouri River, a former stockyards town that's reinvented its riverfront with parks, a casino, and the excellent Lewis and Clark Interpretive Center. It's an easy-going stop on a Great Plains road trip, with surprisingly good Mexican food reflecting the city's large Latino community and a skyline dotted with early 20th-century terracotta architecture.

Traveler reviews
★★★★☆
Stopped here for a night on a road trip and was pleasantly surprised — the Lewis and Clark center was really well done and free to enter.

★★★★☆
Some of the best tacos I've had in the Midwest, honestly. The riverfront park is a nice spot to stretch your legs after a long drive.

Quiet town but the historic Fourth Street district has more going on than you'd expect, with a couple of decent bars.
