We went up here for Memorial Day weekend several years ago and stayed at site #26, without reservations. Great shaded site with water flowing behind it, which made for great sleeping. Campground was full by the afternoon with lots of families but it didn’t seem crowded. Vault toilets were incredibly clean and the whole campground was well-maintained. We hiked a little bit of the Columbine Twining hiking trail - can’t wait to go back to be able to hike more!
