Campground Reviews

Apr 19, 2025
The campgrounds are very well kept. There are so many things for kids and families to do on site. The staff is awesome. Even though we were just passing through, it is easy to tell it is a great place to vacation.

Our site was very nice with a patio and fire pit. Unfortunately this was our second stay when there was no water on departure. Definitely not the KOAs fault as the pipes froze because of the weather.

We have stayed here many times for 1-2 nights. Friendly staff and nicely kept campground.

Great campground in a central location. Our visit was early in the season, and grounds were wet (not their fault). We enjoyed the site and large pet areas.

Always a pleasure to stay at Merce/Grove City KOA on our way to and from Florida. We are fortunate that the campground opens up early in the season and closes late in the season.

Nice location.. old, worn patio floors and fencing. Furniture QUAILTY, however!! Neighbors played music til midnight. Claim Pet friendly, only ground areas! Not allowed in store or bath houses. My 10 lbs. Dog was carried..lots of frown and rude reactions. I will not be back. Others need to form personal opinions.

Ok for a quick stop over while traveling. The pull thru spots are pretty long. No need to unhook.

Thankful for gracious staff that were able to accommodate a change in sites for easier leveling of our rig. The campground is a maze of sites with some roads being a bit tight.

Everyone was very friendly and helpful. I appreciate having an escort to our site who stayed and made sure we were set and knew where everything was before driving away. Everything was very clean. The store was helpful in a pinch My only complaint is that it’s very dark when coming in at night and the roads are very hard to see and figure out what was a pull through or a road.

Mercer is a perfect spot to stay when returning from a Florida winter before heading to the Canadian border. Pullthru spots are easy access and flat, although not side to side level. Beware electrical, sewer drops and water spigots are almost always submerged in standing muddy water. This has been the situation for the past 3 years, but they are the only campground in the area open in April...

We had a 30 amp full hook up site, the electric and water were in a good spot but the sewer was way behind the RV. The planing for the site wasn't very good.

Had a nice place to sit on the deck and enjoy some wine and sunshine. Great place to stop for the night on our way home from FL.

The park was not open yet, but we had a fully serviced drive thru site & the owners were very fair with us & very helpful when we had some rv problems. Excellent park & we will go back again

Being 70 degrees in March, we had to get out and camp! Even though you were "closed", winter camping was perfect! Loved the almost empty campground!!

Camp Ground is well maintained, Good size swimming pool with lots of seating area. There are many activities for families to enjoy. Amish baked goods on Sat. mornings are tasty. The managers and staff are very helpful and friendly. It is also close to other activities.

We love the Halloween weekends! Our kids love the pumpkins, trick or treating, Escape room, and site decorating. They also love the gaga ball pit and RC Racing track, although this time is the full of leaves...lol

Great Community and Pleasant Staff! There's so much to do, a clean and refreshing pool, games/sports activities set up ready to play, fishing pond with easy catches, big dog park with enough space to run, clean facilities and a nicely stocked store. The cabins are clean, well maintained and hospitable. The wifi may be spotty, but there are hotels near by, if camping isn't really what you wanted to do. Great local attractions too!

Woman at the front desk is, by far, one of the nicest people I have ever met!
