Many pull-thru sites, nice green grassy patch at each site. Nice gift shop with a few groceries, and ice cream cones. Very friendly staff. Very pastoral area, quiet and peaceful feeling, even though it is very close to Interstate 81. No Campground area Wi-Fi. Internet available in the office area. Good overnight stopping place. We camped here in a Travel Trailer.

This campground was open all year and was very nice in the winter. The cabin had one room that had a queen bed and a bunk bed and a table and chairs. The owners went in ahead of our visit and turned on heaters so that i was nice and toasty when we arrived. I would like to visit in the summer to use the pool and restaurants. We camped here in a Campground Cabin.

We Camped there for a picnic. Staff were just great and the pool was clean, store small but well stocked with incidentals. Many of the sites were very open. The center pull through have no shade 'cept what you bring with you. Next time I'll try to get a shaded site on the outer edge. We camped here in a Travel Trailer.

This is by far the best KOA I have ever stayed in. My wife and I were there for 32 days and paid the extended stay rate. Everyone was extremely friendly and helpful. I enjoyed the food at the restaurant (except the Taco bar on Wednesday). Seems the Pennsylvania Dutch don't really know what a Taco bar should be like. The toilets, showers and Laundry rooms were the cleanest I have ever come across in a Campground. I highly recommend this park for any one to visit. We camped here in a Motorhome.

While I believe this campground has only recently become a KOA, it has been around for a long time. My in-laws had a brochure from 1971 when rates were $3.50/night. They got a laugh in the office when I complained that the rate was higher then the brochure and showed them my relic. It is important to note that the correct name is Twin Grove Park KOA. Twin Grove Park was originally a local amusement park, and the campground came along later preserving some of the rides and adding newer ones later. The staff was very friendly (and obviously had a good sense of humor) and check-in was speedy. The camp store was well-stocked. The restaurant was adequate. Not 5 start cuisine but good enough if you are looking for a quick meal. We had breakfast there. The pool was nice though with temperatures in the mid-90s very crowded. In addition to the on-site restaurant there is also an ice cream parlor, the amusement park (6 or 8 rides including an old-style carousel), mini golf, and on Saturday night there was also live music. A very good Country band. This was their western weekend so the band fit the theme. They also had horses, rodeo activities, pony rides, etc. In walking around I noticed tennis, basketball, and shuffleboard courts as well. Shade for TTs and motorhomes is at a premium. There are a bunch of shaded tent sites. Our groups only complaints were the lack of shade and lack of grass. Nearly the whole campground is stone, though it is very well maintained and the sites very level. Finally, Swatara State Park is right across the street and there is a semi-improved road that takes you back to the the Swatara Park multi-use rail trail which features a beautiful walk along Swatara creek. The Appalachian Trail runs just on the other side of the creek and, in fact, there were a couple of AT'ers at the restaurant when we were there Saturday morning. We camped here in a Motorhome.

While many KOA parks are giving KOA's a bad name, this is one of the best KOA parks. This one is truely a big rig friendly park with no low overhanging trees, easy access, and easy level pull through sites. Nice small restaurant on site as well as a very nice pool, amusements, playground, entertainment, and more. Not that far off the interstate for an overnight stop. Clean, well maintained, and excellent staff. We camped here in a Fifth Wheel.

Big new KOA with numerous things for kids/groups -loads of space, pavilions, organized activity spaces, large restaurant, store filled with goodies kids will love, friendly management. At Exit 100 of I-81. Gravel level sites, no vegetation between, lovely area in general. If you like KOA's, you'll love this one as it is much larger, newer, less cluttered, friendlier management than most. They even have garbage pick-up! Family style campground. Our Verizon broadband air card and Verizon phones worked well. We camped here in a Motorhome.

Looks like a KOA should but usually doesn't. Amusement park rides looked to be in good condition, park very clean and nice. Not too far from office but couldn't get wi-fi. Scenic, somewhat remote area. We camped here in a Fifth Wheel.

Big Campground. Easy Access to and from I81. Lots of activities in season. WIFI Access works well but only available in vicinity of the office. Sites are large clean, and easy to access. We camped here in a Motorhome.

This is without a doubt the BEST KOA we have ever stayed in. The grounds were immaculate with some full-timers. The staff were excellent. There is a restaurant on premises with good food. There are trees that surround the campground but getting the satellite signal is no problem. All sites are gravel as well as the roads. There is a basketball court, a volleyball area with sand, movie theater, shuffleboard and horseshoe pits. You won't be bored here. They have a large store with RV supplies plus anything else you might need. I would definitely come here again. We camped here in a Motorhome.

This KOA is great. The staff is really helpful and friendly. I'll admit that a lot of their sites are gravel and out in the sun, but there are a number of sites along the tree line, and we had one of those. Our site was beautiful, large, and backed up to a small stream and trees that provided shade. The tenting area is back in the woods and looked very attractive. The bathrooms were immaculate. There are 7 really nice "family baths" near the tent area that consist of a residential style bathroom. There is an amusement area at the front of the campground, with about 4 rides, that looked fabulous for the pre-school aged child. The pool was closed, but large and clean. There are also a bunch of different sports courts. The arcade is huge. Across the street is Swatara State Park where you can kayak or canoe on the stream, if the water's not too low, or ride on the Swatara rail trail. We'll definitely be back here. We camped here in a Travel Trailer.

We camped here in a tent trailer with no air conditioning. We requested a shaded site which in fact was hardly shaded at all. Most of the sites in this campground are open and we were there on a very hot weekend. Would not recommend for someone without air conditioning. The facilities were clean and nice. The staff were friendly and courteous. This campground had a lot to offer in activities. Some amenities we liked: the large pool with water slide, nice arcade, evening entertainment, large campsites, small amusement park, and a full service restaurant. We would stay here again either in early spring or late fall to appreciate the warmth of the morning sun! We camped here in a Tent Trailer.

We loved this campground and only stayed for one night each way as we were passing through the area. We had a long pull-thru which was perfectly level and easy to enter and exit. Staff was very friendly. You have to eat here as the food is very good and fairly priced with good sized portions. Would have loved to have stayed longer. We agree the only thing lacking is a fishing pond, but everything else makes up for it and they deserve the rating. Grounds were immaculate and well cared for. One of the best koa's we have ever stayed at and we are gold card members so we have been to many. We will make it a point to go back to stay again. We camped here in a Travel Trailer.

Very family friendly campground. Friendly helpful staff. Everything is new & clean. We camped here in a Tent.

This is a good park, especially for the fourth of July. They have an amusement park for the kids with rides, and the pool has a small water slide. Pull-thru sites are not shaded but offer a good view of the fireworks show the campground puts on. Bathrooms are usually very nice, but this trip (this was our 2nd time there), they did not stay as clean as before. Also had more noisy neighbors than in the past and had to go all the way to the main gate to find security to ask them to quiet them down. We would return to this park despite the bathrooms and noise issues. We camped here in a Travel Trailer.

We camped here with a several other families in June and had a wonderful time. We didn't use the restrooms, so I can't comment on them, but if they are anything like the rest of the park, then they must have been clean and well maintained. The staff was pleasant and helpful, and they accommodated us all by keeping us all in a loop so that we were together. The pool was awesome, and the kids loved the mushroom and the slide. We will stay here again, without hesitation. We camped here in a Travel Trailer.

A great destination campground. See the web site and other reviews to get a sense of all the things to do. We were just passing through, and it rained the entire time, so we did not get to enjoy the many options available. Nevertheless, we were comfortable in this newer, clean, and efficient location. The individual bathrooms (toilet, basin, & shower) are wonderful. We camped here in a Motorhome.

This is an excellent park with a very helpful and friendly staff. The Pool is great for children as there is a water slide.Highly recommended. We camped here in a Fifth Wheel.

We fully enjoyed this campground. The facilities were impressively clean. This campground had several small play grounds plus a large one that made it wonderful for us, traveling with a preschooler. The small amusement park area was just great for the pre-teen crowd. We camped pre-swim weather so did have a chance to use the pool although it appeared clean and well kept. I don't recall a ton of very shady spots -- (I'm writing this 3 mos later) although there were plenty of trees around. I'd have to go back in the deep summer to see if its too very sunny but it was a good experience. We camped here in a Motorhome.

Only thing this place lacks is a fishing pond, but fishing is nearby. Staff is friendly, great place for kids. Restaurant is excellent. Being a newer campground, most of the sites lack shade and become toasty in the hot sun. There once, and our second trip is reserved. We camped here in a Travel Trailer.

Big Rig friendly, easy access of I-81, large sites, excellent camp store/restaurant, terrific arcade area with kiddie rides. Great setting in the Adirondacks for fall foliage made this a memorable trip. We would definitely return to this well kept and well managed rv park. We camped here in a Fifth Wheel.

Beautiful campground in the Appalachian Mountains. The big rig pull throughs were huge and and grassy. There is a beautiful view from the campground. There is an ice cream parlor, game room and a few rides that are owned by the campground. Every RV site has a free Satellite TV hookup. The Satellite TV has around 28 Channels and is provided by DirecTV. This service came in extremely clear. There are also many sites in this park that are Dish-friendly. The pool was beautiful and had a mushroom and water slide. The roads were well maintained. There was an excellent restaurant on the premises. The chef even came out and asked everybody how their meal was. The food was very reasonably priced. The store seemed to have quite a bit of stuff. I would recommend this campground campground. We camped here in a Fifth Wheel.

By far one of the nicest parks we've been to. We've been on the waiting list for 4 years to get our own site. Lots of activities for everyone, so you or your kids should never get bored. State park across the street for hiking and such. Restaurant is very reasonable with excellent food, in case you want to take a break from cooking. We visit several times each year. We camped here in a Motorhome.

KOA campground. Could use more 50 amp service, but overall nice campground. Nice restaurant and camp store. Ice cream store on site. Nice family campground. Small amusement park on site as well. We camped here in a Travel Trailer.

This park is 50 years young, but looks brand new. The good points include the pool, the excellent restaurant and ice cream shop, and the friendly staff. The bad points were the jammed together sites and the lack of trees, i.e. minimal privacy. We were there during a Civil War Reenactment Weekend and loved the up close and personal view we had in the field next door. We will return next year for the Reenactment (check the web site), but we did find the lack of privacy unnerving. I wish they had left some undergrowth between sites instead of almost clear cutting the woods. We camped here in a Travel Trailer.
