Spring Green was the home of famous American architect Frank Lloyd Wright and you can visit his beautifully designed home, House on the Rock. This house also contains some of the world’s most eclectic and rare collections ranging from an intricately furnished dolls house to the world’s largest indoor carousel. After lunch in Spring Green, continue your journey to Winona. This lush valley town on the banks of the Mississippi River looks as if it could be a Rhineland town in Germany. Stay 1 night at the Alexander Mansion (or similar).
