If you are reserving for 2 or more nights, you may request a specific site.  In order to guarantee a specific site, there is a $10 site lock fee.  You can "Select My Site" with your online reservation at KOA.com to see the best site options for you!  If you choose not to pay the $10 site lock fee, there is a chance you will be moved before your arrival to more efficiently accommodate guests in the campground.

Non-Holidays: 
If you need to cancel your reservation, you must call the campground before the deadlines listed below to receive your deposit refund, minus a $10 cancellation fee.  Not calling to cancel/no show will result in forfeiture of the entire deposit.

If you have a reservation, your site map and instructions will be in an envelope in the night registration area, just to the left of the front door of the office.  If you do not have a reservation, please use the night-registration table to the left of the front door.  There will be envelopes left out where you can write down your information and submit your payment.  Inside the envelopes will be a map to the sites available that night that you can use.  In the morning following your arrival, please stop into the office to complete your check-in.

Friends of registered campers are welcome to visit during the day and will need to vacate the campground by 10:00 pm. There is a $5.00 ($10.00 on holidays) per person per day visitor fee required upon entrance to the campground. All visitors must register at the office. Additional vehicle parking is available in the visitor parking lots. Campground management reserves the right to limit visitors and refuse admission.

Mercer/ Grove City KOA welcomes well-behaved pets and their humans.  We expect pet owners to be courteous of the rights of others to a safe, clean, and comfortable camping experience. Pets that are hostile or aggressive will be asked to leave the campground, along with their owners.  All pets must remain on a leash no longer than 6 feet when out on the grounds, except inside the doggy playground.  Please, do not leave your pets unattended and always remember to clean up after them. Constant barking bothers other guests. If your pet is too vocal, you'll need to find other accommodations.

If you're camping with family or friends, consider our buddy sites!  For RVs, we have three different sets of buddy sites, one of which is an awesome deluxe patio site combination!  

• The Deluxe KOA Patio buddy sites are site numbers 100 and 102.
  
• Our regular pull-thru, full-hookup, buddy sites are site numbers 16 and 18 with another option of site numbers 12A and 15A.
  
• If you're camping in one of our kabins or lodges, we have buddy tent sites to combine kabin and tent camping!

• Kabins KK1-1, KK1-2, and KK1-3 have a buddy tent site, as well as Lodge KOT-3.
  

RV site #116 and Lodge KOT-2 pair together great with each other if you want to combine RV and Lodge camping!

RV site #58 has a perfect buddy tent site to keep your tent friends cozy right next to your RV.

Please call or email to request your buddy site when making your reservation!

We open the pool the Victoria Weekend and close the pool the next Sunday after Labor Day weekend.
Pool Hours are 10AM - 8PM. 
Thunder or storm - everyone is to evacuate from the pool area until it is deemed safe to re-enter.

10PM - 8AM. Please allow others to get a good nights sleep.

5 mph Please drive like your kids or grandkids live here.

Please do not bring firewood into the campground. If you do, you will be asked to keep it inside your vehicle and remove it from the property immediately.
Firewood is available for purchase. $7 for one bundle, $20 for 3 bundles, and $30 for 5 bundles.This wood has been heat treated by a DCNR certified supplier and kiln dried to kill off any insects or disease.

They give you shade. They provide oxygen. Please help keep our trees available for future generations.

Pests traveling in outside firewood, or pallets, have killed off hundreds of trees on the property.
Wood that looks clean and healthy can still have tiny insect eggs, or microscopic fungi spores, that will start a new and deadly infestation.
Aged or seasoned wood is still not safe. Just because it is dry does not mean that bugs can't crawl onto it!
So please, don't bring firewood into the park, even if you think it looks fine.

Thanks for understanding why we can't allow outside firewood, and for helping us save the remaining trees on our property!

Motorized vehicles such as golf carts and ATV's are not permitted in the campground. Electric scooters and mopeds are allowed, provided the 5 mph speed limit and rules of common courtesy are observed.

We pick up trash at your site. Please leave bags close to the road, so we see them. Pick up happens through out the day. Don't leave bags out at night - you may receive unwanted visitors!

We pump propane!  Whether you have a grill tank, motor home, or food truck, we are equipped to pump your propane.  *Check with front office for pricing. Propane filled during regular business hours and cannot be filled after dark.

Cars must fit on gravel of your site. Please NO parking on the grass, it kills the grass and creates mud. Extra vehicles may be parked in the visitor lots.
Please do not park on vacant sites. Vacant sites need to remain available to campers.
Visitors are to park in the visitor parking lots.

We welcome you to arrive any time after 2:00 pm and check-out at 12:00 noon.

Sunday through Thursday a late checkout on RV and tent sites is allowed until 2 pm (if you have stayed 2 or more nights and the site is not reserved for another guest).
Extra fees may be assessed in accordance with early check-ins or late checkouts.
NO early check-ins or late checkouts on Fridays, Saturdays, Cabin sites, or Deluxe Cabin sites.

Sleeping tents are only allowed on tent sites.
One Sleeping tent per paid Tent site. No sleeping tents are permitted on RV or cabin sites without a separate reservation.

Guest wifi is free with no password.

We have trees. Lots of trees. There is no guarantee that a satellite signal will be accessible from any site on the park. Guests staying in spring, before the trees leaf out, and guests staying in fall, after leaves have fallen, have the best chance of success. There is cable on every site.

The concrete bath house in the back of the park, between sites 40 and 41 is the safest building on the campground.

It's a great day at the Mercer/Grove City KOA
