Everyday prices are the government's average for the parts of Missouri outside metro areas, not Potosi alone. Check current listings before you budget.

Getting around

Straight-line miles. The road is always longer, and as the book says, an interstate at 70 is a different trip from a farm road at 45. Check the real drive: St. Louis.

Washington County is outside any metro area, with fewer than 5,000 people in its towns, next to a metro area (USDA rural-urban code 8, on a scale where 1 is the biggest metro areas and 9 the most rural counties).

For a day

3 places on the National Register of Historic Places, including the Washington State Park CCC Historic District.

National Park Service sites within about an hour:

  • Ste. Genevieve National Historical Park40 miles
  • Ulysses S. Grant National Historic Site48 miles
  • Ozark National Scenic Riverways54 miles
  • Gateway Arch National Park57 miles
