The campground features 12 waterfront tent-only campsites scattered throughout the island, offering seclusion and spectacular views of the Canadian shore or the shipping channel. Campers can beach or moor their boats near their campsites. The island's terrain includes steep rocky outcroppings and several foot trails for exploring. The park provides a unique island camping experience in the Thousand Islands with picnic facilities, fishing opportunities, and a peaceful wooded setting.
