Thousand Islands National Park protects granite islands and shoreline along the St. Lawrence River. Shortlist it when you want island camping, paddling, boating, and big river views, especially if the setting itself matters as much as the available date. Thousand Islands sits in southeastern Ontario and is managed through Parks Canada. With 61 indexed sites, it has a compact camping inventory, so date flexibility can matter a lot during peak weekends and school-holiday windows. The best trip fit is usually decided by the landscape first: water, trails, beaches, cliffs, quiet forest, or simple proximity to the region you already want to explore. Because it is a Parks Canada location, final rules, permits, fees, and booking flow still belong on the official Parks Canada side. For planning, scan the setting and current availability here first, then confirm final details with the operator once the park feels like the right match.
