Overview

The Mercer/Grove City KOA offers a quintessential Pennsylvania camping experience characterized by its lush greenery and welcoming atmosphere. This well-regarded park serves as a comfortable home base for exploring the diverse offerings of Mercer County. With its spacious pull-thru sites and well-maintained grounds, travelers can expect a balance of modern convenience and the serenity of the outdoors. The park is thoughtfully designed to accommodate everything from massive rigs to traditional tent campers, providing a reliable and scenic retreat.

Located conveniently near the intersection of I-79 and I-80, the park provides easy access while maintaining a peaceful, rural feel. The scenic countryside of Mercer surrounds the property, offering a quiet escape from highway noise. Visitors will find themselves tucked into a landscape of rolling hills and hardwood forests, making it an ideal spot for those who appreciate natural beauty without straying too far from major travel corridors. It provides a perfect transition between the urban centers of Pittsburgh and Erie.

This destination is packed with features designed to keep every family member entertained during their stay. Guests can enjoy a dip in the heated seasonal pool or challenge each other to a round of mini-golf on the park’s custom course. For children, the jumping pillow and gemstone mining station are perennial favorites that encourage outdoor play. Pet owners will particularly appreciate the dedicated KampK9 dog park, ensuring that four-legged travelers have plenty of room to run safely off-leash.

Nearby Attractions & Things to Do

One of the biggest draws to the area is the Grove City Premium Outlets, located just a short drive away for world-class shopping. Beyond retail, guests can explore the historic craftsmanship at Wendell August Forge or visit the charming village of Volant for local boutiques and specialty foods. The nearby Living Treasures Wild Animal Park offers interactive wildlife experiences, while the surrounding Amish countryside provides a glimpse into a simpler way of life through its roadside stands and picturesque farms.

Who This Park Is Best For

This KOA is an excellent choice for family vacationers seeking a resort-style environment with plenty of structured activities for children. It also serves as a premier destination for shopping enthusiasts looking for a comfortable place to stay while visiting the nearby outlets.

Awesome KOA and cool escape rooms. Near the Grove City Outlets in Mercer. All staff members are great to be around and make you feel welcomed. This weekend featured a trick or treat on Saturday night. We were unsure if we would ever visit another KOA after visiting the KOA in Erie. Look at my previous review before trying the KOA further north. I will never forget how bad they treat their visitors. The Mercer KOA receives a 10/10. The staff, campers and kids were great. We also were not afraid to go outside of our camper at quiet time like the Erie KOA, because we didnt want to get kicked out at 1200 at night. 🤣 Thank you Mercer KOA!

We camped here for our anniversary weekend to go to the outlets and just relax. Such a nice place. The staff are very friendly, welcoming, and helpful. Decent size store with needs and fun things. We had forgot a few things and the store thankfully had them, but if it didn’t we were close enough to other stores in the area which makes this a very convenient location!! They have local Amish bring baked goods on Saturdays which was nice and we had treats for Sunday morning breakfast. Then they held a campsite trick or treat. We enjoyed handing out candy to the kids as they came by with their families. Bathrooms are clean and our tent site was within a comfortable walking distance to one set of them. Thank you KOA for a fun and relaxing weekend!! We will be back again next season!!

Great KOA! Upon arrival check in was easy and customer service was great. Very family friendly. This time of year the it’s beautiful with colors, trees, birds, activities and Halloween fun. We only stayed a day but definitely worth coming back.

This KOA is basically our home away from home and we love it. We have come to know the staff very well over the past 5 years since buying our camper. They are always so friendly and accommodating. The sites are always clean and well taken care of, and everyone goes the extra mile to make you feel welcome. If you are planning to stay in this area, I highly recommend this campground.

One night stop. Nice staff. Campground was clean, nice dog park. Didn’t get to use the pool. Clean restrooms. Pretty quiet. The site that was assigned to us (113) was hard access (turns) and not very leveled. We have a 47ft 5th wheel. If you want a big rig friendly spot maybe ask for a spot closer to the entrance (probably more than what we paid?)

Very nice park. Unfortunately just an overnighted for us. Roads were a little tight with a big rig pulling toad but the sites were a good size. Manager or owners (not sure) were very nice and helpful.

Muddy ...no cable. We stayed there before and had excellent sites. This site was poor but with all the rain I guess it was to be expected. Friendly office staff.

This place does everything well. You can tell the owners and staff take great pride in their park and it is maintained very well. The park is full of trees and has the feel of a state park. They were also very accommodating and helpful when my truck required unexpected repairs. When I realized how remote the park was I thought the price seemed high but based on all the amenities they offer it is priced very fairly.
