Nice park and a busy place. If you are really interested in horses, this is the place to be. All sights are back-in and they have three dump stations, so no problem. All sites have plenty of room, so have more trees and shade then others. We were just here overnight. Easy to get to; just followed the instructions from Map Quest.
Nice KOA . We have had bad experiences with KOAs so usually stay away from them, but traveling on I-79 there were very few RV parks, so gave this a try. You do have to be careful getting there. I used the directions from Map Quest and got there great. When they say behind the Days Hotel they mean just that. Register at the Days Hotel. And there is a buffet after 5 PM at the hotel you can use. The meal is wonderful.
Great park, very friendly staff. We only stayed overnight but will definitely go back again and stay longer. Small road going in so beware, but we thought it was worth it once we got there. Our 40 foot RV + towed = 62 feet long fit just fine. A nice gentleman escorted us in and went to the store for milk, they didn't have what we needed and someone was going into to town and they picked it up for us. There are a lot of permanent trailers but when we were there it was all quiet.
This was a nice park for the location. We were only five miles from the Falls and the tour agent was on the RV grounds, which was handy. The tour bus picked us up and brought us back. WalMart was only two miles down the road. There was a lot of traffic on the road but it is a main road. When we called to make sure they had room and we were told check in was 1 PM. If you show up early they would charge you $10 per hour, so be aware.
