We entered the park looking for a walk-up spot and landed on Site 67 which was not reserved. The site was spacious with a big tree with good shade and cover if needed. Also, it had a great fire pit with grill grate that could be moved. It was the perfect overnight location and cheap accommodations during the National Balloon Classic. We spent the night before at the Balloon Glow, came back and had a nice camp fire, then an early morning rise for a balloon flight made for close proximity. There were nearby bathroom facilities that were available. The truth is that the one closest was not lit well and a little messier, perhaps less maintained. The other facility was well lit and not too far a walk. During day light you could see the lake in the distance from this site, and the clearing around the site gave great visibility of stars with very low light pollution. The only downside was this site was near the main entry and exit road on the lower loop, which meant traffic in and out could prove to be a downside. Not for us on our stay at night because of late arrival and early departure, but it is good to know. All in all it was a good stay, the only challenging part was knowing which sites were available and the camp hosts weren't too helpful in knowing or seeking which were still open. But we were lucky to find one!
