We made an impromptu trip to escape the heat and unwind. We were grateful the stars aligned and snagged a FF spot! The sites are spacious and very well kept. Yes, you are right next to 89 regardless, but it worked fine for us. The creek is easily accessible and walking distance to a trail head as well. Firewood and ice are available on-site and the camp hosts graciously drop it off at your site. It is a quiet campground and to note is that music is not allowed. 

Afternoon rain in the canyon is such a treat and we couldn't have ordered it!
