Linn County, Kansas

Linn County sits along the eastern edge of Kansas, right next to the Missouri border. Mound City serves as the county seat, and the area is largely rural, with several small communities scattered throughout.

The Marais des Cygnes River runs through the county, offering opportunities for fishing, boating, and enjoying scenic views. The surrounding landscape gives the area a peaceful, natural feel.

Linn County is also home to the Marais des Cygnes Massacre State Historic Site, which preserves an important reminder of the region’s turbulent history. Another advantage is its location—Kansas City is close enough for an easy trip when you’re looking for more urban amenities.
