O'Reilly Lake Resort
A family resort on spring-fed O'Reilly Lake, about 7 km south of the 7 by Frontenac Road. There are RV and tent sites, cottages and small lake huts to rent, a beach, canoes and kayaks, and an inflatable water park out on the lake for the kids. For decades it was O'Reilly Lake Campground, a summer standby for Kingston families, until Summerhill Resorts bought it in 2021.
