One of Minnesota’s most popular attractions is Minnehaha Falls, a waterfall smack dab in the center of Minneapolis.

The fifty-three-foot-high Minnehaha Falls was purchased by Minneapolis in 1889. It was the centerpiece of a new state park. The falls remain one of the state's most popular attractions for both residents and visitors. Their name is derived from the Dakota words mni for "water" and gaga for "falling" or "curling"—literally "water fall."
