About Franklin County

St. Louis Metro & Eastern Gateway
Land & Farm

Rolling working farms and hardwood timber on the metro's rural edge.

Franklin County is where the eastern gateway becomes real country. Rolling countryside carries genuine working farms, pasture, and hay ground, threaded with hardwood timber along the ridges and creek bottoms. The Missouri River runs the county's northern edge, and the land south of it climbs into wooded hills that hold whitetail and turkey. This is prime territory for the buyer who wants a working or hobby farm, a cattle place, timber, or a recreational tract with room to breathe — all while staying within practical reach of the metro. The mix of productive ground, water, and cover gives Franklin an honest agricultural character that the counties closer to the city have largely traded away. It is countryside you can still farm and hunt.
