Campgrounds and RV parks near Brockville, ON

Brockville sits on the north shore of the St. Lawrence River in eastern Ontario, roughly midway between Kingston and the Ontario-Quebec border. The city anchors the eastern end of the Thousand Islands region and serves as a practical base for RV travellers exploring the 1000 Islands Parkway, Thousand Islands National Park, and cross-border trips into upstate New York. Options within an hour of the city run from waterfront provincial and national parkland to full-service private RV parks. Pleasure Park Campground and RV Resort sits north of town, while North Country Cottages and Campgrounds and McLear's Cottage Colony and Campground provide smaller family-run stays. The Log Cabins fill out the mix for travellers who want a cabin option alongside RV sites. Just across the river in New York State, Jacques Cartier State Park is located in the Thousand Islands region of New York along the St. Lawrence River with waterfront access and views of the St. Lawrence. Highway 401 crosses the top of the city, and the Ogdensburg-Prescott International Bridge sits a short drive east for U.S. crossings.
