Steuben County
The northeast corner of the state, providing our first line of defense against the possibility of a joint invasion by Ohio and Michigan, Steuben County is also a motherlode of nature preserves. Glacial action has left kettle lakes, swamps, marshes and bogs (and maybe even fens). Spend a weekend or a week here - you can camp at Pokagon State Park, you can even stay at the inn for all I care, I'm no purist - but visit here you must!
