The campground had nice appeal and a good layout. The wireless Internet (WIFI) did not work; the guy at the counter said it had been out for a few months and that they hoped to fix it in the future. (They did let us plug into a cable in the laundry, which worked OK.) I would have rated it a 8 or 9 if the Internet worked.
A typical KOA - nothing super special but close enough to Toronto to get in and out OK. The WIFI worked well. The playground was a little run down and the campground is a few hundred yards from the Interstate, so noise was pretty high. Would stay here again.
As KOA campgrounds go, this one was nice. Shady, clean and quiet. The roads were very tight for us (40'). We arrived after dark. Normally, the campgrounds leave pamphlets with a spot marked, but not this one. After walking around in the dark for a bit looking for a spot, the very grumpy owner came out and led us to a spot. Not sure if I blame him or not, as we came in at 11 PM. Other than that, it was a pleasant experience.
Really nice. Super friendly and helpful staff. Brand new pool and hot tub. No mature trees. The facilities were top notch; they must have spent a fortune building this place. Which probably explains the cost. Never seen anything quite like it.
We camped at Glacier Basin. We have a 40' RV and were able to squeeze in a spot with a bit of maneuvering. (The site was obviously designed with much smaller RV's in mind, though.) The sites were level, but cramped. Nicely equipped with a modern fire ring and level raised tent camp area on each site. The staff was very friendly and accommodating.
Of every campground we have ever camped in, this one was our hands down favorite. Heavily wooded and shaded, very private, the real deal. Lots of huge trees surrounding all the campsites. We camped in a 40' RV, and we were towing. It was tight, but doable. No cell phone coverage.
We reserved late, so this was the only Yellowstone campground available at the time. Although the campground had a lot of open space, the actual camp sites were very small. The fire ring was on the driver's side of the site. We had a difficult time fitting the motorhome and tow vehicle in the space. There were no trees at all. Bison were omnipresent in the campground. But, hey, you're in Yellowstone!
