Site 10 had boatloads of ants -- so many that we ditched our reserved site and went for a walkup site over 10 miles down the road. I've never seen that many, there were probably 10-15 ants per square foot in every inch of the campsite and they latch onto you so not easy to shake off. Bummer since it's an absolutely amazing site otherwise.
Other sites in the campground had ants as well to varying degrees. Had to drive out 10+ miles to find a campground that had a normal amount of ants.
