    I arrived late on a Sunday afternoon which was nice because most of the weekenders had left. The campground has a nice mix of seasonal sites and transient. I'd say it's about 50/50 in terms of very shaded campsites and somewhat shaded, which is nice in the summer months to help keep your RV cool. I was there for a week and their staff was always around during work within the campground, and for the most part it was clean and what little I used of the bathrooms, I found them to be clean as well. The main issue I had with the campground was the septic smell - at times it was really bad. I only noticed it in the back of the campground where they appear to be doing work so I'm not sure if it's a temporary problem or it's always that bad? A couple of days the weather was very nice, I opened my windows and every now and then you'd get a waft of the smell and a few times it nearly brought me to my knees. I had stayed in site #52 and felt the map was a bit misleading...it was a long campsite, but it was extremely narrow and when sitting outdoors I felt like I was sitting next to the road...actually, I WAS sitting next to the road, which was annoying at times. Thankfully, it hadn't been too busy during the week so there weren't many cars that were passing by on a regular basis. One thing that may have caused me to camp elsewhere was their lack of cable TV even though they advertise having it on their KOA website. I know, I know, I'm camping and why do I need it, but I camp alone and there are times when I'd like to watch TV or catch up on the news. Thankfully, I was able to pick up approximately 20 OTA channels from Youngstown, OH. My point is, don't advertise that you have it, and when I go into the office to advise the cable isn't working at my campsite and have the teenager behind the counter laugh and tell me it hasn't been operational for a while...not cool. Not a major issue, but something that may have affected my decision making. It's worth noting this campground isn't far from Route 80 and I noticed many people stopped in for the night and were on their way the next morning. If you're planning on checking out the area, Pittsburgh is about 1:00-1:15 minutes south, easy peasy.

    A real fine campground, which was neat, clean, quiet and well maintained. We were escorted to our back in RV site by Ellen, the friendly store manager. We had a nice level site (. # 69) with water, electric and sewer and cable hookup. There was a swing, a fire ring/ grill, a wood deck and a table with 4 chairs and an umbrella. WiFi was a bit pokey, but not too bad. Very nice set up. They pick up your trash every so often, which is a great perk. The pool was small, but very sweet, as was the playground, bocce courts and dog play area. Showers and bathrooms were spotlessly clean and I feel this was one of the best campgrounds that we have stayed in.

It is huge with so many…read moreactivities that you could literally spend your entire vacation here and never leave the grounds. I recently visited with my partner and our two kids. Let's just say, we aren't totally the dedicated campers where we need to pitch tents, bring all the accessories and sleep on the ground. That's why this place especially stood out as they had luxury cabins for rent. Or as my partner said, I'm good as long as I have air conditioning and running water! The cabin came with a screened-in porch, an outdoor fire pit for evening s'mores, a loft where the kids slept, a full living room and kitchen with refrigerator another room with bunkbeds, a bathroom and then the master bedroom at the back of the cabin complete with dressers to put away your clothes. I'm one of those people that always unpacks and must have things organized, so it was a lifesaver. You can rent golf carts, highly recommended as the grounds are spacious and some of the cabins are located far away from the activities. There are also communal laundry facilities, which were great to have since we had to use them day 1 of our trip! The common area offers free activities like playgrounds, mini golf, character meet n' greets and wagon rides along with firetruck rides. Other activities cost extra like ceramic making, tie die shirt making, glitter tattoos and several others. Some nights they offer free movie screenings and other programs. Overall, this was like camping without the pain! That's my kind of camping. Cabin rentals are a little pricey, but with all that space, it could accommodate a large family or even combine it with others to help split the cost. Finally, the biggest hit was the water park. This is a can't miss. We got a poolside cabana and spent most of our days here. The kids didn't want to leave!

    Let me start off by saying everything is really nice there. When we went the water park was closed…read morebut it looks like kids would have fun. It looks to be more for smaller kids rather than teens but nonetheless it's nice. All the staff were really nice. They took the kids for a ride on the fire truck which all thought that was cool. My complaint if you want to call it that is the price. It's a bit expensive. Camping is suppose to be a cheaper alternative to going to a hotel. Not the case here. Depending on what you get it could be just as much if not more than going to a hotel and I don't mean any hotel local to here. It's comparable (at least when we stayed) to hotels in Myrtle Beach. I won't say I would never go back but it would not be my first pick however if you want to stay local to this area and when I say this area I mean within an hour or two, this is not bad.

I think Cooper's Lake imports extra fireflies just for us (we don't have them in CA) and this year's fireflies didn't disappoint! I wish it had been easier to get our trailer storage contract started by phone though. I had been trying to call to begin a contract a year ago (yeah, COVID) and even several months ago was still unable to get someone to give details or make a commitment while I was trying to communicate by both phone and email. I hate leaving such important plans to last minute, hoping it could happen when I got to site,but that's what we ultimately had to do. Perhaps having a little more info for what to expect in this process be available on the website would help the uber-planners like myself. All in all, thanks for being my favorite annual vacation! There is a lot of planning to provide good infrastructure and Cooper's Lake Campground does it right.

    Visited this state park for the first time earlier this month and had a blast!…read more I parked at what I think is the main lot, up above the mill itself. I didn't take a tour of the mill (which the park volunteers and staff do offer throughout the day) but I did walk through it and read the information in it about the history of the mill. Definitely enjoyed exploring and learning. That said, I was really there for the trails, so I spent most of my day hiking. I took a loop trail down from the mill and back (with a detour up a short trail to some falls) and it was great! I love being outside and I love a good challenge; these trails were not paved or even at all and I had a great workout navigating them. During hydration breaks I'd find a nice rock to sit on by the water, which was wonderful. It was noisy as heck by the mill because of the families, but the further out I got the more peaceful it got. Definitely met my goal of unplugging for a day during my trek on the trails. I want to come back in the future and begin to try to walk the Slippery Gorge Trail, as it sounds like the gorge is another beautiful part of the park. But that is definitely a long term goal, because that trail is not a short one! I loved visiting this park and I'd be back for sure. To everyone else, PLEASE remember water and wear the proper footwear - while I enjoyed my walk in the park, these trails are definitely not a walk in the park!
