We enjoyed the campsite we had at 116. The campground was clean and the staff welcoming and pleasant. We would visit here again.

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.

we absolutely love this KOA. The people working there go above and beyond in every sense of the way. Cathy, who works the desk, is the sweetest person ever. She remembers my name, greets me, chit chats etc. She is big part of the reason why we keep going back.

Nice park, close to the outlet mall which is always a fun place to shop, along with good nearby restaurants. My site was level, and my FHU utilities worked good. Our site was a spacious pull through. Our Oct timing made the place pop with fall color. Verizon had good coverage there.

Was just a one night stop on a cross country jaunt. The grounds were beautiful and well kept and the hosts were wonderful. Five stars all around!

Not much to do as far as hike/ scenery. Big parking lot with hookups. Parked camper then ten foot of grass then next camper. Very expensive for oct 108.95 per night. Pools closed no in door pool or hot tub. were 30 feet from 2 lane 55 mph road. Also it’s the road to cross to the fishing pond Nothing really to do for adults. playground for kids was nice. Campers next to us called it money maker l

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!
