We weren’t able to use the water to drink and the bathrooms were locked.

Came in winter. Koa book said self contained. Overpriced for no water anywhere no washroom facilities & no propane/no store. 43$ for electricity should have stayef in Walmart! Always can count on koas. Am a Canadian snowbird.

Unfortunately, we stayed during a terrible cold spell. Anxiously awaiting another opportunity to stay here.

We only stayed one night but your facility has to be one of the nicest KOA's we have ever stayed in. I even took pictures to show family. :)

Too cold for any of the activities but great site. Glad you are open year round!

Stayed overnight early in the season. Park nearly empty. Friendly staff. Water wasn't yet turned on, but easy to fill at the convenience store. Cute cabins. WIFI was good. Site level. Easy in easy out.

It is a very nice park and the fuel and propane on site are extra very much appreciated benefits. The only comment I would make is advertising “open all year” is not quite true in that no showers or bathrooms were open. Suggest stating that limited services in winter depending on weather. Otherwise very good park

We were tired after a long day of driving on snow-covered roads.and arrived when the Campground was in the process of being plowed out from a major snowstorm. We got stuck in the campground. The manager stopped his plowing and went out of his way to help us get into our reserved site. Those in the office were extremely understanding in getting us situated for the night. Jerry and Donna T

Was here during snowstorm. They did a good job of plowing. There is a lot of road noise. Very friendly and helpful staff. Will deliver pizza to your site.

When we arrived to our site - it was very dirty. Garbage left all over, in burning pit and all over the site. I had to remove garbage from parking spot so we could park without damage to our rv. There was also a knife on the parking area. we told the staff about it - we stayed two nights, nothing got cleaned up while we were there.

Mostly empty in the back area and water is still off due to cold weather. Gravel pull-thru site was good overall but not level side to side. Sewer connection was a bit far from the pad but we could reach it with one hose pulled full out.

did not use showers or laundry. We were there in March so there were not many people there. Very nice fenced dog area. good places to walk. Had pizza delivered to our site from the on site café.

We stayed here in early March. Happy that it was open and available, but with NO bathhhouse available (including showers) they are price gouging at $40+ per night for only electric hookup!!! Looks like a nice KOA, but obviously the owners have one thing in mind: Money!

Awesome place to stay!

We didn’t use the water park. Just the campground. Have stayed at this campground several times and has always been good.

We always recommend this KOA to anyone going through that area even if they have to go out of their way a little to use this KOA. This is our favorite KOA. Nice to find a campground where they understand they don't have to put everyone right next to each other if they have space. This KOA still has a speed limit problem with their permantees not understanding what a speed limit means.

Nicely laid out, our dogs were very happy to have their own space. Quiet and clean.

It was our very first camping trip. The campground was well set up, we enjoyed having a deluxe full hookup! The patio set up and fire ring were well worth the additional price. It provided a great environment to get together with friends and make memories. We will be back again!

The campground is picturesque in the Shenadoah Valley. Campsites are nice and maintained to 5-star standard.

I have been camping there for several years and always loved it til a few months ago. Staff knows nothing! A bunch of kids who havent been properly trained. Checking in is a nightmare. My husband argued for twenty minutes with the girl because she said we couldnt use a koa gift card. This is the same gift card we had been using all summer. Wont be going back next year if changes arent made.

Great stay as usual. Had a problem with the 30amp circuit which was immediately repaired. On this survey add a NA response for the Waterpark. It was closed during our stay and not everyone goes to it when it is open!!!!!!
