Sioux Falls to Fish Creek: Ultimate Road Trip Guide

This 575-mile route from Sioux Falls, SD to Fish Creek, WI crosses four states and the Mississippi River twice. It's anchored by I-90, I-94, and US-41, with a final stretch on WI-57. The drive reveals a transition from Great Plains to Great Lakes forest.

The route roughly follows the terminal moraine of the Wisconsin glaciation. You'll climb from 1,400 feet in Sioux Falls to over 1,600 feet in central Wisconsin. The last 50 miles plunge into the Niagara Escarpment, the same formation behind Niagara Falls.
