We had a last minute change to our travel plans. The young man on the phone was very helpful. The cabin was clean and comfortable. The grounds were well taken care of. Although our stay was only one night, we would come back.

Stayed in the small cabins . Was very nice ! Inside was very cozy loved there was a fridge and tv ! The pool was nice aswell (wish the hours were longer though, especially now when the sun doesn’t start setting till 9 , 9am-9pm would be my recommendation) but other then pool hours I have no complaints! Staff was super nice and friendly, had a lot of games set up , the Amish bake sale ! Lots of f

The only thing I would mention on an otherwise amazing stay is that the door to our cabin didn’t close all the way on the bottom. We did have to seal it with a heavy cooler before going to sleep. While we didn’t mind, I did want to point this out to someone!

Park employees were extremely courteous. Would like to use the trail around the lake and also the nature trail but they were both not well maintained. These would be big incentives for me to come back if mown better, grass around lake very high (ticks & poison ivy risk). Played outdoor games--chess, ping-pong, horseshoes, volleyball, gaga ball. Loved these activities and hope to do it all again.

Shared a long weekend with our adult daughter and her family. Supported them with their new “full hookup” travel trailer first time use. We stayed in cabin L2 (kitchen & bathroom) . Great memories. Definitely will return later this summer…

It was wonderful! Friendly staff!

Everything was great, I loved it. But there is one thing - I whacked my head three times right on the corner of the roof by where I parked. Ouch! I was just cutting the corner to get into the cabin (in the flower bed or on the perimeter of the bed) and wasn't paying attention, then BAM - a direct hit to my head. So after the 3rd hit I figured I should tell you. [email protected]

stayed in lodge 2. great cabin. however, the mattress in the bedroom DEFINATELY needs replaced, 2 people absolutely cannot sleep in that bed , even when only one person is in the bed, you automatically roll to the center, and it would be helpful to have a better light above the kichen sink, it is ok as a nightlight, but when doing the dishes or cooking after dark there is no light over there

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.

We had a group of 15… 3 cabins and two camper sites. This was our third year to reserve the same weekend. Your activities were all so much fun. The escape room was terrific. Cindy was so much fun on the hayride!!!! It’s a really great place to spend a weekend!!

Cabins rock!

Everything could have been great. Nicely maintained campground. The cabin was very clean. There was however one major issue. I stayed their for 3 nights and the TV signal was so week on every subscription I tried (5 different ones) but always got the same result after watching for a very few minutes, I got constant weak signal buffering. It made the nights very long and boring.

As usual - have been camping at Mercer/Grove City KOA since 2018 - we had a wonderful time. The lodge was clean and met our needs very well. The folks at Mercer/Grove City are so friendly and accommodating. Will see them again next year.

My family loves coming up Labor Day weekend! We have been doing this for about 20 years! I look forward to it because it usually falls on my birthday! The pool was perfect! The power went out a couple times which was a bummer but the pool was great! Music was awesome and loved Grocery Bingo! The only thing missing was Jungle Terry! My family and I look forward to seeing him on Labor Day! A+++

What a lovely campground and the ladies working there restored my faith in humanity. They were so beyond nice, friendly and just genuine and that made our weekend even so much better. The whole campground was perfect

Beautiful campground. Very clean and updated. I would have liked to have a gas grill at our campsite. We had a blackstone though. Really enjoyed ourselves! Thanks

Great stay! Love the events for kiddos! So much to do with pool, playground, fishing, mining etc! Glad pup can come too!

Our stay was great. My wife and I were riding bikes in the area and found this place to stay. Staff was great and cabin was clean and comfortable. Will definitely be back again as there are more trails we did not get to do.

Good stay, clean cabins but did have a lot of WiFi issues this time. They were attentive and quick acting in response but had issues multiple times. Need to boost the connections.

Amazing Staff and beautiful grounds

We stay in L-2 and everything was super inside the cabin. Everything worked very well. However, the outside patio area was always sunny, even at dinner time. We didn't have a workable umbrella to provide any shade at anytime and someone had to stand on the table to put it up.

While we wanted a stress free July 4th weekend, Mother Nature had a different plan in mind as the whole campground lost power the day before. While the power outage was beyond KOAs control, they handled it like pros! Employees made their way around the campground checking on guests! I have never seen that at a campground! Location is great, right off Interstate 79 and just a couple of miles from Grove City Outlets! July 4th morning they had fresh Amish baked goods for sale and 3 young ladies selling coffees and lattes! Campground was great overall with wide sites and we ended up turning our site into a “buddy” site as we were camping with other family! Lots of trees and although close to 79, the campground was quiet and peaceful! Highly recommend!! 👍🏻

Our stay at the Mercer/Grove City KOA was the perfect way to end an unforgettable father-son road trip from El Paso, Texas, back home to Pennsylvania. The campground was clean, quiet, and beautifully maintained. Our camping cabin was comfortable, spotless, and exactly what we needed after many days on the road. The peaceful setting made it easy to relax and recharge before our final drive home. A special thank you to Anthony and Jennifer for their outstanding hospitality. They were both incredibly friendly, accommodating, and genuinely helpful. From the moment we arrived, they made us feel welcome, and their customer service is exactly what every campground hopes to provide. They truly helped make our stay memorable. We were also traveling with our dog, June, and she loved the campground as much as we did. The grounds were perfect for relaxing, walking, and enjoying one last evening together before heading home. If you're traveling through western Pennsylvania and looking for a clean, well-managed KOA with exceptional people, I highly recommend Mercer/Grove City KOA. We will absolutely stay here again the next time we're in the area.
