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!

Susan and Richard always go above and beyond with your stay here. We have been enjoying their campground for many years now (8 to 10). We typically only camp there in April/May or October as we are busy during the summer, but we are always treated very well and will continue to visit them every year.

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.
