Sugar Island Camp is a 35-acre island campground owned and operated by the American Canoe Association (ACA), situated in the heart of the Thousand Islands near Gananoque, Ontario, close to St. Lawrence Islands National Park.

The island is accessible year-round to ACA members, either by paddling approximately two miles from the Canadian mainland or via water taxi service available from Misty Isles Lodge in Gananoque.

The camp hosts an Annual Encampment each summer and offers a range of camping options including tent sites, platform sites, and seasonal cabin rentals. A large group camping area is also available outside of encampment periods.

ACA membership is required to camp here, with daily rates varying for members and guests; children under 12 stay free.
