Wildwood Conservation Area is a wooded Upper Thames campground around Wildwood Reservoir near St. Marys. Shortlist it when you want reservoir views, trails, and relaxed southwestern Ontario camping, especially if the setting itself matters as much as the available date. Wildwood sits in southwestern Ontario and is managed through Upper Thames River CA. With 536 indexed sites, it has a large 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 managed by Upper Thames River CA, local conservation-area rules, fees, check-in details, and seasonal conditions still belong with that authority. 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.
