Sioux Falls takes its name from the waterfalls on the Big Sioux River that cascade through a park right in the centre of the city, a surprisingly scenic, free attraction in South Dakota's largest city. Beyond the falls, it's a compact, growing city that serves as a practical base for exploring the wider prairie and as a gateway towards the Black Hills further west.

Frequently asked questions

Traveler reviews
★★★★☆
Falls Park was a nice surprise — didn't expect a real waterfall right in the middle of a Midwestern city, and it's lit up beautifully at night.
Wendy K. · June 2024
★★★☆☆
Pleasant enough stop for a night on a longer road trip, with a decent downtown for dinner, but not much to fill more than a day.
Greg N. · September 2023
★★★★☆
The Sculpture Walk made for a nice evening stroll downtown — good mix of pieces along the main streets.
