I stayed at this Campground having not seen it before. That said, I was expecting a traditional KOA. That was not the case. It was a nice campground but did not have the standard bathrooms I am accustom too. That disappointed me! The check-in process was in a convenance store that closed early and reopened? Not sure I would come to this KOA again. It appears that their focus in only families!

Beds lousy. never before had to pay damage deposit. No cooking utensils for micowave Which was out of reach for handicap people. Had to bring all own cooking utensils. Was a nice facility but lacked alot of things at the price we had to pay. At a motel at least we would have had breakfast for about the same cost and comfortable beds.

First thing off season and we had to get a different cabin because the other wasn’t clean and we also had to shovel the deck and ramp because of ice and snow 2 times other wise great place

The lady at the check in counter was very rude, and tried telling me that I didn’t have a reservation because my confirmation email did not have a cabin number on it. After we finally got it figured out, I got to the cabin and it was clear that it hadn’t been cleaned since the last person left. There was a balloon under a bed still and party favors in the couch. It took me an hour to check in.

Disappointed there were no showers.

This was my third time staying at this KOA this year and the only time I had any issues. I had reserved a deluxe pull thru with a patio but when we arrived they informed us that they had accidentally given our site to someone else and that they only had 9 sites with water due to the cold weather. The staff was rather passive to my wife but when I went in we figured something out that worked for us

Just an overnight stop, but we liked the spaciousness of the campground, and the scenery. Concert lot was level. Full hookups convenient. Only negative was minor...goose poop all around so just watch your step. The older lady at check-in seemed abrupt, but the younger gal there was very friendly. We would stay again if we,re traveling in this area. Nicest KOA than we've seen in years.

We didn’t stay. In spite of the website stating that the park is open year round it is not! We could stay but no water available! After driving over 6 hours in heavy rain to get there, we had to drive further. Young employees sitting at entrance using f$&@ over and over again. Will NEVER stay here! KOA needs to check on them or we will no longer stay at KOA. Very disappointed in KOA.

Not much shade, trees not mature. Clean bathrooms close to a newer playground. Our campsite was next to the playground and was disappointed that the kids were allowed to play well after dark (signs were clearly posted). We enjoyed the nearby water park with our grandchildren.

Very nice campground. Did have to "find" the level spot on our site. Sewer is at the very back of the site while other hookups are in the middle. I our case we were so far forward in the site (parked Tow Vehicle behind) that both Sewer Hose extensions I carry had to be used. We camped in a Fifth Wheel.

Easy registration and quickly sent to the site. The site was gravel based and it had an uphill slant that resulted in my stabilizers lifting the real wheels completely off of the ground. The park was well maintained and all the amenities were more than adequate.

Nice park. Only two complaints. 1. why do you bunch everyone up tightly with the entire park open? 2. You cannot control this but my site was littered with dog poop all around my hookups. Maybe if you would escort people to the site you would notice such issues. My first stay here a week earlier also had a site littered with trash.

Very nice park! I like site #1.

Just a quick overnight stay but staff were friendly and welcoming. Camp sight was level and easy to access.

We checked in, after driving around the campground a half an hour to find our site occupied we went back to the office. We're told to take any site we wanted. It was dark, we have a 45 foot camper and towing a vehicle, had no idea where to go, roads were not lighted and we have no idea where the large pull though sites are. They finally sent a person to help us find a site. Never again!

Was a great park. Friendly staff and nice layout. My only reason for not giving you a 5 star rating is there was a dog pile in the grass next to our picnic table. Since we don't have a dog, I don't like having to pick up after other peoples dog.

We were here out of season but would love to come back in the summer. The water park looks amazing! Beautiful views and the sites are nice sized. This KOA also has a gas station!

We arrived after dark. The outside driving lanes were fine. However, the turn into the lane to our space was hard to see. I circled around a couple of times before I got it. It looks like this park is a lot of fun in summertime!

Its really a cool spot, we are a little over an hour away, so its a nice place to relax and unwind and dont have to travel far. Even in the off season, the cabin was comfortable, and just a nice hangout.

Sites are level with plenty of room between them. Long enough to leave our pickup attached to the motorhome. Lots of places for our dog to run. Will stay here again if we travel through here.

It was very convenient and value priced

Just a over nighter, all was OK, the weather was a downer with the wind.

We loved the camp ground but the cable tv didn’t work for us and told management twice about it with no resolution or response.

Great location, plenty to do...decent sites, friendly staff. Everything you are looking for in a vacation spot or overnighter.

The good. Nice facilities that are well taken car of. Our pad was level, hookups were convenient and not too close to neighbors. The store is well supplied and the prices are very fair. The bad: The "cable" did not have many channels - we ended up just using our antenna. The wi-fi is spotty at best, we ended up using our phone data for anything we needed reliable service to access.

Lost Island RV Park is a nice park. We have stayed here 2 years in a row to visit relatives in Waterloo. Quiet park.
