For KOA Holiday Mercer Grove City: Beautiful and clean. Easy to find. Lovely trees. Dog park, great store. Nice staff. Lots of spacious sites. A bit costly but overall worth it. We stayed here in a 44’ fifth wheel in April 2022.

For KOA Holiday Mercer Grove City: New owners really are
making this KOA special. Very large, clean dog park. Spacious patio sites. Landscaping is pretty. We have a 40 ft Foretravel and tow a car. A tiny narrow exiting, make sure you know where to go to leave, we were in site12 and took a wrong turn hitting some rocks, not fun. But we loved this place and will be back!

For KOA Holiday Mercer Grove City: We loved this campground. Nice wooded area. Spacious sites for the most part. Friendly staff. We were in the area for a reunion and and a couple of old friends had sites near us adding to the enjoyment. I highly recommend this campground.

For KOA Holiday Mercer Grove City: I made a reservation for 2 sites. Both we’re Wednesday thru Sunday. We have a large rig and my daughter have a smaller travel trailer. I called back and made our reservation for the week, about 2 weeks before we arrived! There were lots of sites up front that closer to my daughters site, we could have fit on but the put us next to the road for a week. They could have moved us since we were here for a week. Not happy about that! Other than the road noise for a week it was nice.

For KOA Holiday Mercer Grove City: Very nice park for an overnight from the warm south to the cold north. 3 miles off of I-79 and the overnight pull through sites are large and very level. The only small issue is that my GPS kept telling me about the “10-ton†restriction on the road.
I have a 40’ class A, paid $53.50 and stayed 5/7/19.

For KOA Holiday Mercer Grove City: We stayed in the cabins a few years ago and in our A Class 36' this time. Enjoyed the pool, friendly staff, site numbers hard to find, some areas a bit hard to get around in a bigger rig but overall we enjoy this park. Nice trees, birds, fishing across the road, convenient to Grove City outlet shopping.
