Frontenac (/ˈfrɒtɛnæk/ FRON-teh-nak)[5] is an unincorporated community and census-designated place (CDP) in Florence Township, Goodhue County, Minnesota, United States, on the Mississippi River.

[7] In 1854, brothers Israel and Lewis Garrard came upon the area during a hunting trip and bought large tracts of land.

[8] The railway ran from north to south and connected the remote area to larger cities, but it was far enough away from the bluffs not to detract from the vacation destination.

Frontenac State Park includes the floodplain along the Mississippi River, bluffs which are a flyway for many migratory bird species, prairies and hardwood forests.

It is within the Mississippi Flyway and is also part of the Driftless Area of the north central United States.

Amtrak’s Empire Builder, which operates between Seattle/Portland and Chicago, passes through the town on BNSF tracks, but makes no stop.
