We rented a rental trailer for 3 nights and only stayed for two nights. Even though we paid for all 3 nights. The beds were so uncomfortable we couldn't stand it for another night. Smelled musty when we first went in and the vents were open, there was also a damp spot on the carpet from the rain. There were many things that were not good but would make this post too long. Save yourself the hassle... We rented a rental trailer for 3 nights and only stayed for two nights. Even though we paid for all 3 nights.

What a great experience we've had so far. Everything from booking to enjoying has been so effortless and pleasant. I'm sorry this may be a longer review but there is a few things to cover. THIS IS THE ONLY REVIEW YOU WILL NEED... I have read them and there are some that not only seem impossible they are most definitely misguided! First. The layout and amenities, we are tenting it and the sites here couldn't be more private, spacious and well maintained there are spots to suit everyone's taste from secluded and tree covered to a bit more open for family activities. Also it's just minutes from the highway. Secondly, The owners and staff are beyond incredible if there's an issue (there isnt) but they are on top of everything. I value customer service and enjoy when people take pride in what they offer and let me tell you .....Susan is the most amazing hands on operator I have ever met. When we arrived she was there to great us, when ever we wanted to use the well stocked store she was there to assist, she worked the breakfast restaurant and her along side her husband held a raffle prize table and had a band here for Labour Day Weekend. WELL IF SHE WASNT OUT GETTING PEOPLE DANCING ON TOP OF EVERYTHING ELSE INCREDIBLE!! All proceeds went to camp for kids with cancer and the passion and emotion her husband showed along with pride to be able to do what they love while allowing people to have a great time and win prizes but also was extremely visibly passionate about helping the kids. It has been a true pleasure to get to know them a bit while witnessing this amazing place they have built together. Lastly, the facilities are impeccable from the well lit extremely clean washrooms to the pool that welcomes all ages and abilities along side a very nostalgic mini putt and a jumping pill for the kids that is just one of those things that will instill a life time of memories for all that are lucky enough to attend this place. To summarize our stay it has been our pleasure to meet such great people in such a relaxed fun place. People who really care that you and your family not only have a great time but also care about what they offer and proudly provide to the patrons. ****they even deliver firewood to your site**** unbelievable!! To Susan and her husband as well as all the hard working staff like Christian and son we appreciate the hard work and dedication in to this magical little slice of land . Sincerely thank you from the bottom of our hearts thank you for saving our vacation and providing the vacation we needed and deserved.All the best in the future and with out a shadow of a doubt we will return again and again and possibly decide to invest in a seasonal trailer all because of you guys. Keep up the fantastic work!

Nice clean campground. Check-in staff very friendly. Took the time to explain all the campgrounds facilities and hours. Kids loved the playground and bouncy pillow. The highlight was the heated pool. This is their favourite pool so far. It was clean and in great condition. Bonus is the shallow area for the young ones and pool slide. Our site was clean as well with good power and water pressure.

The highlight was the heated pool. This is their favourite pool so far. It was clean and in great condition. Bonus is the shallow area for the young ones and pool slide. Our site was clean as well with good power and water pressure. We will return next year. Surprised they charge for mini-put. No other KOA's we've visited have a charge for this.

We were disappointed with our recent stay at the Mallorytown KOA. While the fireworks and live band were enjoyable, the overall experience was overshadowed by how the campground was managed. Although we respected the 11 pm quiet time, even quietly sitting by the campfire with friends was treated as “too loud.” This made the atmosphere feel more restrictive than relaxing.

While the fireworks and live band were enjoyable, the overall experience was overshadowed by how the campground was managed. Although we respected the 11 pm quiet time, even quietly sitting by the campfire with friends was treated as “too loud.” This made the atmosphere feel more restrictive than relaxing. More concerning for us was a situation where our son and his friends, ages 10 to 14, felt uncomfortable with how a rule was enforced. We believe it could have been handled in a way that better respected their privacy and created a more positive experience. In our view, speaking directly with parents would have been a more appropriate approach. When we shared our concerns, we felt we weren’t taken seriously. While the campground does have some enjoyable features, the strict enforcement of rules and how this particular situation was handled left us uneasy. I wish I had read past reviews before booking, and I would encourage the owners to reflect on feedback to create a more welcoming and family-friendly environment moving forward.

We had a great time here! The campground was very clean, well-maintained, and had a family-friendly atmosphere. Everything was organized and taken care of with attention to detail. We truly enjoyed our stay and would definitely come back again. Special thanks to Susan for being so helpful and attentive throughout our stay – we really appreciated it!

This family owned campground is immaculate! Though there are seasonal sites, the transient sites are placed perfectly on the hillside with views of the Thousand Islands. We even saw tankers going by. The sites are spacious and well kept. The sweet welcoming gift was a nice touch. The location was perfect for us to enjoy the area.

We have been coming to Merry Knoll for many years. Always have a great time. Joanne & Jim are the best. Jim is always checking on everyone to see if they are comfortable or have any problems. I would recommend this campgrounds to anyone

The only thing this place has going for it is the view at the very end of the campground. Overall the campground was more permanent residents than recreational campers. Many of the permanent residents had dogs that roamed freely off a leash and did lots of barking. The owner Jim was not really a welcoming type. My husband asked if we could have a late checkout the following day. At first when he... The only thing this place has going for it is the view at the very end of the campground. Overall the campground was more permanent residents than recreational campers. Many of the permanent residents had dogs that roamed freely off a leash and did lots of barking. The owner Jim was not really a welcoming type. My husband asked if we could have a late checkout the following day. At first when he asked Jim he sort of grumbled and told my husband to go see his wife to pay extra and sign papers. My husband did and asked if we could stay until 2-2:30 and she charged him the extra. When we got back from our boat tour at 1:45 Jim was waiting at our site obviously angry. He said to me “glad you’re back”. I said, “Thanks. Yes we made it back safely.” Jim said in a nasty tone “No, I mean I’m glad you’re back because I have someone waiting for your spot”. He then proceeded to tell my husband we have to pack up because someone is waiting to pull in. We asked if we could stay until 2-2:30 the latest. It was only 1:45 when he was rushing us out. I found this to be very rude since we already paid for extra time. We basically felt like we got kicked out to let someone else in. This situation was not handled properly at all. This experience is unlike any that we’ve ever had with other campgrounds. Needless to say, we will not be back nor would we recommend this place.

Nice campground with great view of the river. Very welcoming owners. Bathrooms are clean. The complimentary carrot cake on arrival was delicious. Merry Knoll is conveniently located to Clayton.
