Oahe Downstream Recreation Area, South Dakota

If you wanna go big on recreation, Oahe Downstream Recreation Area is the spot to do it. Measuring 231 miles, it boasts one of the largest reservoirs in these United States, connecting the capital cities of North and South Dakota. Three campgrounds provide ample opportunities for everything from boating to disc golf, but definitely don’t be a buster and pass up the opportunity to peep bald eagles that perch within 50 feet of the riverbank in the cottonwood trees. We also recommend stopping by the butterfly garden located near the main entrance to the park. There you can learn about native prairie plants, and how to identify these majestic insects.
