Be prepared to listen to pounding bass music until quiet hours start, I was in a camper and could clearly hear every note. Forget about sitting by the fire, and I can’t imagine how it is for tent campers. The owners should inform campers at the time of booking if there’s also a wedding booked, or at least that there’s a chance a wedding will occur during their stay. The owners obviously choose not to inform paying guests who are camping because they can get away with it - By the time you find out there’s a wedding, you’ve already paid and aren’t going to leave in the middle of the night. I requested a refund for the night of the wedding which was denied by management, however I was able to succesfullly charge back the night in question and would encourage other campers to do the same if this happens to them.

We like to camp in our RV here along with our cats. We were supposed to camp in early October but one of our cars needed surgery and had to wear that cone of shame. That being said we couldn't go when we planned. However we did not want to canel and Gloria at the reservation desk was able to push us out 2 weeks. She and all the staff associated with KDM KOA were simply wonderful people to deal with. We would have taken up their offer of 15% off our next reservation but we just dont have a time in mind for next year. We will be back!

We didn't stay over night but we did mine and shop at the store. The whole resort was well laid out and clean. Our experience mining was wonderful and I also bought my gal a nice diamond ring a bracelet for a great price.

Rented a glamping pod (in what I new realize is the off season). Store/office is closed by 5 post season-which makes it a challenge to get things you need (firewood) if you are off site for the day. While its lovely its in the middle of the woods, truly... it presents the added challenge of not being able to get things you need locally. I was on the mountain side so never really explored the main campground as I was off site during daylight hours. Glamping pod is as described-small but functional. It would be tight for 2 people but worked for me (solo). Wish they'd add more hooks in the pod. Water was nice and hot for shower 👍👍

Was not advised that I would be awakened by chain saws at 8-am, nor that the campground is an active construction site with heavy equipment moving around. Terrible! To add insult to injury this is a VERY over priced facility @ $109 per night. Find somewhere else to stay, your wasting money and begging for torment. All management would do is say " I'm sorry you feel that way" from Freshman psychology. Better environment in a Walmart parking lot!
