Big skies, red-rock mesas, and prairie grasses waving in the wind—Oklahoma is a frontier waiting to be explored. Scramble granite outcrops in the Wichita Mountains, watch bison graze tallgrass, or chase waterfalls in the Ozark foothills. Lake-lined campgrounds invite boating and bass fishing, and Route 66 diners serve up fried-pie fuel for the next leg of your journey. Rugged yet welcoming, the Sooner State is pure road-trip country.
