This was our first stay in any campground as new RVers. The gentleman who checked us in was so nice and helpful. The space and hookups were great. The woman who checked us out and filled our propane tank was also so friendly and helpful. What a great first experience!

We just had a quick overnight here while traveling. It was off season but all of the facilities that I used were clean and in good repair.

I loved that there was breathing space between sites, that the store was open until 10 pm (because we ran out of propane at 9 pm), and the wifi worked!!

Nice park with walking path around one lake. I believe a casino is close to resort, but we didn't visit casino. KOA staff at office when we arrived.

This is not your average KOA. This is beautifully laid out and has to be relatively new. Lake, beach, long pull throughs, and great donuts in the main office, store. You will like it. diesel station in front also. Gary

Your sewer connections are too high on the site. Two times I've stayed and both sites the connections were too high to normal flow. I had to keep backing up nearly out of the site to get my RV connection higher than the connection. Bad stuff.

People were great and helpful, nicest KOA we have ever stayed at. Outstanding off-season prices.

Outstanding. Very clean. Staff were fun and professional. Nicest one we have ever stayed in. We will be back.

The staff is great, but the shower houses are not cleaned like they state they are. The park is quite except when the casino has concerts. Then there is no getting away from the noise. This was a complaint by many campers.

Beautiful park and fish in the lake, I caught 2 Largemouth Bass in 10 minutes. Very handy location, a little road noise but overall a great 2 night stay.

Park was friendly & clean. Only issue we had was the traffic in & out till late into the night. Not road noise but people staying in the park.

The campground, facilities, and staff were all just fantastic. The cabin was cramped but a good value for all the people in it. Definitely would go to this specific campground again in a second.

Just what we wanted and worked for all of our needs.

We had a great time except for the wet campsite. If it's rainy, don't stay at site 46 because it becomes a river.

Carl and Pat are outstanding!!! If every KOA had people like these two, we would go every weekend!!If you needed anything they helped you immediately. Get more people like this! Lance & Sonya

What a beautiful park! Modern, great layout and very spacious sites. Great cell reception and Wi-Fi. Wouldnt be nice if all RV parks were this nice. Thank you very much! Thomas and Sandra Crochetere.

Lovely and peaceful semi-rural setting. Large spacious sites. Pleasant staff and very helpful.

This is a fairly new KOA and they keep making improvements. Our first stay was in May and when we returned in September you could feel and see the difference. Bathrooms were very clean, even after a holiday weekend.

This is our second time staying with this KOA location and it is peaceful, CLEAN, and the staff were as wonderful as ever.

We were hoping it we would be able to swim but it was cold so having other activities like the battle boats and water bikes, the volleyball court, and bikes made it a fun time any way. Also had a hot dog roast! The walking trail is nice.

Love this location! The gravel track around the pond needs constant work on the washed out areas!
Sep 16, 2015
It was a great stay will go back.

very nice campground.

A previous stay was satisfactory however, our recent holiday stay of 5 nights was not. Although we booked 4 months in advance,and there ended up being other open sites our site was in the very back row near a pit,no picnic table, cable was hit and miss, internet only worked when park emptied,and site was unlevel due to rutted blacktop surface.Sites are not marked well.Disappointed!
