Expansive, scenic state parks abound in Minnesota, covering so many different landscapes that comparisons of one to another are practically unjust. But given one dart -- and one dart only -- to toss at a map? Aim, then, for Whitewater State Park in the southeast and its miles of cool rivers, steep bluffs and deep valleys. Fish for trout here, too, or roam among the 28,000 acres of adjacent Whitewater Wildlife Management Area, listening for drumming grouse or gobbling turkeys, or alert for eagles soaring high overhead.
