Host was helpful. If in an RV make sure you have water before you arrive only a hand pump at camp. Water is available at Watpi campground about 20 east of 3 mi. Very close to Yellowstone east entry.

3 mi from East entrance of Yellowstone was perfect. Quiet clean campground; no hookups. Only allowed hard sided campers due to Bears. Next to river was very nice.
