Nisswa to Keystone Road Trip: 8-Hour Prairie & Badlands Drive

The drive from Nisswa, Minnesota, to Keystone, South Dakota, covers 470 miles via I-94 W and I-90 W, a journey that typically takes about 8 hours without stops. This route crosses the transition from the hardwood forests of Minnesota's lake country to the vast prairies of the Dakotas, culminating in the granite peaks of the Black Hills.

Notably, the highway shadows the glacial moraine left by the last Ice Age, and near Murdo, South Dakota, you'll intersect the 100th meridian—the historical dividing line between the humid East and the arid West. This geographic shift is palpable in the changing vegetation and climate.

The highways are in excellent condition, with wide shoulders and clear signage. However, be cautious of strong crosswinds across the open plains, especially in winter when black ice can form. Always check weather forecasts before departing.
