Very nice and new. But since it was at the beginning of the season,but our firepit was full of garbage, including beer cans.Other then that we had a good time, we played bingo and hubby went fishing.

Very nice campground. This ia a large campground that is close to a waterpark and also close to conveniences. The employees are very friendly. Our dogs love the K-9 playground.

All was good other than they switched our reservations and didn't know another camper was in our spot when we got there.

It was a beautiful campground however they did not have any of the restrooms or showers open even though they are open year round.

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!

Simply wonderful! We look forward to returning to this location.

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.
Oct 18, 2015
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.
Oct 03, 2015
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.

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
