We had a reservation at a nearby campground that was cancelled due to a water main break. Recreation.gov showed 4 sites available at Black Canyon Campground. I tried booking each of the 4 separately but had the same issue. Once I went to checkout i received an error message that "this site is already reserved and unavailable". This is even though it showed 'available' throughout every step until checkout. I waited until the following day to see if something was amiss with the website. This time it showed two sites available. One did the same thing as the day prior. I was able to book the other site, #11. Upon arrival, #11 had only a pullover spot to park our van and it was only about 6 ft wide. So our van was in the middle of the road. Amongst other concerns, everyone walking the campground passed withing inches. It was also on a significant hill, very far from level. Steps led to a table and tent site, but we stay in our van. The photo was of the table/tent site only. This was exceptionally unacceptable but since we had nowhere else to go and it was 7 pm..... Recreation.gov charges a fee for themselves. I expect an accurate website, not showing sites are available when they are not. I also expect that unacceptable situations to be revealed. Our van is a standard size van. Anyone in a small RV or larger could not have stayed there as it would have blocked the road. This is the first negative experience I have ever had booking a site in many states. Transparency of what to expect can alleviate a lot of issues.
