Follow the Lewis & Clark Trail to Onawa / Blue Lake KOA Holiday, located in the heart of the Loess Hills (pronounced “luss”)—unique formations created thousands of years ago. You can view the topography along Loess Hills National Scenic Byway. Relax at this quiet, rural campground that offers shade trees & open, grassy areas. Enjoy lake sunsets & the wind whispering through trees. Let the kids (or the kid inside of you) take a dip in the pool & explore the KOA with paddleboats or fun-cycles. This KOA is located on the lake, with fishing & boating for all to enjoy. Free Wi-Fi! In June, the area hosts a Lewis & Clark Festival with a keelboat display, quilt show & reenactments—or visit the Lewis & Clark Interpretive Center year-round. Try your luck at Blackbird Bend Casino (5 minutes away) or get your motor running over to the Onawa Dragway. Open April 1–Oct. 31, weather permitting.
