Campgrounds and RV parks near Prescott, ON

Prescott sits on the north shore of the St. Lawrence River in Leeds and Grenville County, directly across from Ogdensburg, New York, and linked to it by the Ogdensburg-Prescott International Bridge. That location puts RV travellers within a short drive of campgrounds on both sides of the border, in the eastern gateway to the Thousand Islands region and roughly an hour south of Ottawa. On the Canadian side, the closest full-service option is the Cardinal / Ottawa South KOA Holiday, a family-focused park about 20 minutes west of Prescott off Highway 401. Smaller private grounds in the area include Wildwood Campground and The Log Cabins, plus additional St. Lawrence Parks Commission sites farther along the river toward Morrisburg. Across the bridge in New York State, Eel Weir State Park sits on the Oswegatchie River south of Ogdensburg, and Jacques Cartier State Park is roughly 30 minutes downriver on the St. Lawrence near Morristown. Both are seasonal parks operated by New York State Parks and reachable from Prescott without a long transit.

Reservation systems split by border. New York State Parks, including Eel Weir and Jacques Cartier, book through ReserveAmerica. Campsites can be reserved up to nine months in advance, and same-day bookings are accepted online until 3 p.m. on the day of arrival. Maximum continuous stay is 14 nights, after which the party must vacate the facility for 48 hours before re-registering. Cardinal / Ottawa South KOA Holiday books directly through the KOA website or app, with KOA Rewards members earning a discount at checkout. Smaller private grounds such as Wildwood Campground and The Log Cabins typically take reservations by phone or through their own websites, and holiday weekends should be locked in early. Proof of rabies vaccination is required at check-in for pets at New York state parks, and Ontario rules prohibit moving firewood into provincial and commission-run parks.
