Living Waters Campground Twin Mountain, NH Outstanding location along the Ammoonusuc River clean, quiet and safe. Facility is showing it's age but this is a great location with plenty of activities. 

NOTE: NO ALCOHOL IN OR OUT OF YOUR RV OR TENT ALSO NO CURSING. 

Having said that the owner operator and his family live on the premises and couldn't be nicer or more helpful.

Colorado State Park System

Rifle Gap, Rifle Falls, Steamboat Lake and Ridgeway you will not regret visiting any of these in my opinion all are outstanding places to camp.

Gros Ventre in GTNP any short comings in facilities is made up for with outstanding views an great staff. No reservations makes it iffy during peak season. When we were there they had 14 nights in a row when the were full by mid-afternoon.

Madison Campground YNP again location, location, location reservations are a must during the peak season try to book in February or March to be sure of your summer days. no hookups but great staff. I advise you to call and not use the online system as you have more flexibility. Some spots are very tight for the larger rigs.

Want to get away from the crowds at Yellowstone try Slough Creek Campground up in the Lamar Valley. Drinking water, vault toilets and no generators but solitude and wildlife abound. Don't go out without your bear spray. We saw a black bear roaming through the campground at noon.

Emerald Lake State Park Vermont, dry camping but a beautiful location and outstanding swimming.
