No, it's not a campground it's a parking lot. There's a place not far on 370 that provides what u seek.
Cabelas does not have an established policy for those who want to camp out near their stores. Because they are not open 24/7. Stores like Walmart are more welcoming to those who want to spend the night. Also the Cops will check with you if sleep over at the Cabelas parking lot.
