Stayed for a nite and it was ok...just a place to park and that was all we needed. Then I went for a shower. It had rained all night and I walk in to find the bathroom floor wet and the ceiling leaking. Then my shower never got beyond lukewarm. So my three stars means.. Meh! For this KOA

Love this campground. Reasonable rates. Friendly, helpful staff. I feel like the sites are spaced well enough apart that you dont feel as tho you're on top of your neighbor. The sites along the water are beautiful. Again, lovely place to camp...my favorite locally.

We enjoyed our first stay here in September 2025. Check in was extremely friendly. Camp store was visually appealing and looked to offer some fun options. Cabin was extremely clean and well cared for. The best offering of outlets we’ve ever seen in a primitive cabin! Fun stuff offered for all ages, and also great food offerings on some days. Restrooms were clean. Only minor downfalls were that we felt that parking at our particular cabin could potentially be tricky. Also some cabins are a little too close for comfort, as we felt it difficult at times to not feel like we were in our neighbors laps. Overall we loved it here and most definitely have added it to our list of preferred stays when traveling in that area. Highly recommend! You can see a video of our experience on Hammocks to Coasters on YouTube.

3.5 stars rounded up for benefit of the doubt. We stayed in a cabin and glad I didn't have to maneuver an RV or camper through there, rather tight. Our cabin spot was the smallest cabin site we've ever had, with a car parking right in front of our patio for another cabin. Disliked that. But cabin was clean, bunk bed bedding was strange. Loved the pool area on the hill and store well stocked. Pizza delivered to our site was nice!

Extremely convenient. Close to the highway. The roads are very dusty because everything is just gravel. The staff was very helpful. They have a guide in a golf cart that takes you to your site. The store was fully stocked. The restaurant was very nice and clean. We had a pull-through site. We only stayed one night as we were heading south. But we would definitely come back here as there's a lot of history in the area. It's really nice being on the river. We would have liked to have gone kayaking but did not have a chance. We had water, sewer and electric, full hookup. The sites are very close together and we were at a site with two cabins which happened to be empty during our stay but if they had had people in them it would have been overwhelming. I love how they have flowers everywhere. They also had some really cute ducks.
