At only $8 per night with the annual Access pass, ($16 without it), this close to Yellowstone, its a steal!! Thats without hookups. Loop A and B have some walk up sites, everything else is pretty much packed. I checked RV parks in West Yellowstone, ( 60 to 90 per night) and the campgrounds inside the park (no 4G service mostly) and this one is the best option we found. Shade, privacy, boat launch, nice hosts, we love it. Some spaces have electric. Dump station is 17 miles away in town for $ 6 at Grizzly RV park.
Rustic National Park Service campground. There was about 2 miles of dirt road to get there. Camp host was very friendly. Very forested and shady with spacious sites. Short walk to the lake. Pit toilets. Only a few miles to West Yellowstone. I would definitely stay there again.
Camped in Grant within the Yellowstone park the last 3 nights- SO NOISY and no hookups. This campground is $16 base with $7 fee for an electric site. Drove up today and they had availability. Great cell coverage (we have AT&T and had no service in the park). Bathrooms are primitive and there's no sewer hookup, but for $23 for electric and a beautiful, shaded *quiet* area, this can't be beat!
