I tent camped and booked online earlier on the same day (use this link, the one listed above is incorrect: https://www.campspot.com/park/riverside-campground-scottsbluff-ne). For only $10, I certainly had everything I needed. The restroom had an access code, which should be provided at check-in. The only downside was that there were a few pesky bugs, but it is “Riverside” after all. If you’re going to Scotts Bluff, I highly recommend this spot!
