We stopped here for one night, we just needed to get off the from from driving for hours. I figured this was a safe bet since it had a self pay station I guessed it didn’t have a gate that closed. The first thing you come to is the national monument entrance and since it was after hours no one was there but there was no gate so we kept driving. You twist and turn up to the top then get to Saddlehorn Campground, we pulled in around 10:00 on a Monday night thinking not many people would be there, wrong, there were lots of people! Luckily some sites were open they were reservable sites but the reservation didn’t start until Tuesday so we were able to pay for the site for one night. The self pay kiosk states that you can use cash, fill in credit card info but no personal checks. Restrooms were very nice and clean, well maintained. No shower facilities. Water is available.
