Campgrounds clean, good size dog park, pool very nice grandchildren had a blast on the slides. Our second time there, 1st time something went wrong with their sewage and the smell unbelievable, this time we unfortunately hit a decorative bolder with the motorhome. We understand our issue, however another camper could have the same issue. Owners did not seem to care and never bothered to even look

Everything was fine. Until we lost our power, then we had to rough it for a day or so. Our condolences go out to the family that lost a father, and left a little girl traumatized. Hope everything goes well with her.

Liked it although we had 2 power outages and a tornado (1 death on our campground). We didn’t have any damages but we unfortunately had to leave 1 day before our reservation ended because power was not restored and temperature was in the high 30s. We couldn’t sleep without our A/C.

A beautifully well kept campground - the staff were fantastic - so friendly and helpful - you could clearly see they loved what they do. We would highly recommend staying here. We thoroughly enjoyed our stay.

Was a wonderful stay, lots to do and very quiet there, close to other amenities, had no issues what so ever. Susan is a great lady, kind, courteous, and very friendly. Will most likely go back again next year.

Susan et Richard sont des hôtes exceptionnels, très attentionnés aux besoins des campeurs! Les sites sont grands, bien entretenus. La piscine, le resto, les jeux sont des atouts qui répondront aux besoins de tous! Merci et nous reviendrons!

Outstanding!!! Best KOA we have stayed in. Large, very well groomed property, excellent water, power and double sewer hook at our spot. Extremely polite and knowledgeable staff in the office. Excellent grounds staff who went out of their way to help with specific propane filling requirements!! Definitely a must stop at KOA

Très beau site #208. Parfait pour la famille. Grand terrain super bien aménagé. Nous avons adoré la piscine. Très propre. Nous avons apprécié les coupons pour la croisière dans les Milles Îles. Le seul point négatif est que les toilettes étaient loin , ainsi que les poubelles et recyclages. Bref nous avons eu un magnifique séjour.

Quiet, warm shower, dry spot, lots for the kiddos to do. Recommend a stop at the Rapid Valley Restaurant before you return to the 401.

The Marcoux family is always welcoming. We come back every year, as the campground is prescient, nice large sites, close to decent biking and hiking trails and the 1,000 islands. The owners always go above and beyond to make your stay the best!

Convenient location near the highway, sites are spacious, and everything is clean and well maintained. Owners are friendly.

We camp there quite often and are always pleaased with the services. The Saturday afternoon Bingo is also fun and Susan always manages to make it amusing and hilarious. Looking forward to a few more trips there before the end of the season.
