Everyone was so welcoming! We stayed there for 7 months and the staff (shout out to Kurt) went above and beyond for us! Thank you for being our home away from home, it made being so far away, a lot less lonely! Thank you thank you!

Nice quite place, well keep with level sites. It's not easy finding a campground that can hold a 40 ft RV towing a P/U truck (Which brings me to 66 feet in lenght). If we are in the area again, we WILL camp there again.

Greeting from front desk was amazing, thanks! Disappointed in my site .. muddy as if some type of construction had been done at some point. This lead to cleanup constantly from myself and dog. When I stepped off my steps, I stepped directly in mushy mud. Don't get me wrong but I paid for a site of almost $70 and had to deal with mud?? Not a good deal .. sorry, just being honest.

In spite of the weather we had a wonderful time. I loved the fenced in dog park! It was much more specious than other dog parks in KOA's. The people were friendly and the grounds and bathrooms were clean.

Always a great stay. Since we don’t live very far away, this is our “go-to” campground. I went into the front office upon getting to the campground, and I was greeted like I was a family friend. �. I would recommend this campground to anyone.

The location is beautiful and the staff make it easy to get reservations even off season. We stay one night in March and sometimes February on our way back and forth from the south in our class A Motorhome. There is plenty of room and full services.

It was great! They plowed our site before we got there. Map was waiting for us and we got a phone call to let us know where everything was. They were great!

Had a great time . Heading west sio I used this time to learn about trailor living. I have to give a big shout out to Kurt for all the help and good advice that I desperately needed from day one frozen water to hitch problems. Thanks Kurt!

We stayed at the campground during off-season travel. So appreciative Mercer was open! Staff were exceptional in accommodating our needs. Our site was long and perfectly level. Dog park is huge! We will be back.

After season. Sites were in excellent shape. All services worked. Bathrooms clean and warm. Host called before our drive to give us number for emergencies, host checked on us before leaving. Will always try to end our season here. Great campground, will make plans to come in the middle of summer!

Great that they let you stay this time of year when you are traveling and only need overnight!

Was great. Loved the escort to the site, since it was dark when I arrived. The site was in the back corner. Seemed to be the best location for all the pet owners to bring their dogs to go potty unfortunately. There was an issue Sunday morning, the water pressure stopped. Not sure if due to everyone flushing or mechanical issues. But the kids had a great time and that was our goal.

Our 1st season was amazing. Clean, friendly and full of activities! Excellent swimming pool! The best dog park of all KOAs. Campground is beautiful with large sites, trees and a fishing pond. Amish baked goods on Saturday morning always fresh and delicious. Fall brought the Escape Room, wagon rides and decorating contest for Halloween with Trick or Treat. We had a blast, see you soon!

Another amazing year at the Mercer KOA. We love being seasonal at this KOA and plan to be there for many years to come.

My family has camped at this KOA since 1980's and we are permanent campers. We have been there with the ownership changing hands a few times. The present owners and manager take pride in their ownership and job. We thank you and your employees for all your hard work in letting us enjoy being at your campground. The Schohn's Site 46.

Always enjoy our stay. Campground needs some tender loving care. Cable would be nice but understand the expense to install

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!
