Florence is situated in the Upper Peninsula border region of northeastern Wisconsin, positioned close to the Michigan state line along the Menominee River corridor. Neighboring communities within reasonable driving distance include Iron Mountain, Michigan, roughly 25 miles to the northeast, Niagara, Wisconsin, approximately 15 miles to the east, and Crandon, Wisconsin, about 45 miles to the southwest.

Community & economy
Florence has the character of a tight-knit Northwoods community where outdoor recreation, natural resource industries, and small-town traditions form the backbone of daily life. The local economy has historically been tied to timber and mining, with tourism and outdoor recreation now playing an increasingly vital role as visitors come to fish, hunt, snowmobile, and explore the surrounding Nicolet National Forest. Daily life in Florence revolves around community gatherings, local schools, and the seasonal rhythms of a region that experiences dramatic changes from its snow-laden winters to its lush, green summers.
Transportation
Florence is primarily accessed by highway, with Wisconsin Highway 101 and U.S. Highway 2 serving as key corridors connecting the city to neighboring communities and larger regional centers. Travelers heading to major commercial airports typically rely on the Ford Airport in Iron Mountain, Michigan, or drive further south to Austin Straubel International Airport in Green Bay for broader flight options. Public transit options in this rural Northwoods setting are limited, and personal vehicles remain the primary mode of transportation for most residents and visitors.
History
Florence County and its county seat were established in the latter half of the 19th century, a period when the region's rich iron ore deposits and vast timber resources attracted settlers and industry to the remote Northwoods. The area's iron mining heritage played a significant role in shaping early Florence, and evidence of that industrial past can still be found throughout the county in the form of historic mine sites and local landmarks. Over time, as mining and logging declined, the community adapted by embracing its natural surroundings, transitioning toward a tourism-based economy that continues to evolve today.
