Michael - I found this campground when I first went on a day trip to see the ruins after a tip from a family member, and I camped there in May 2002.
The Rockwood Conservation Area is located only 15 minutes east of Guelph, Ontario, and it is in a great location for those of us living in southern Ontario. It takes only about 45 minutes to an hour to get there from the GTA (Toronto/Mississauga/Oakville) and is located in the small town of Rockwood. The price is right, and it is located near the town grocery store, so it is easy to run in to town for ice, drinks, or extra food. There is also a drive-in nearby, and a pool hall. The campground itself has sites with or without electricity, sites for campers, sites for tents/trailers, and even group sites. There are grass lots and forested sites with good privacy. All sites are just a short walk from a picnic area with a covered concession stand with tables, showers and bathrooms, miniature golf, a baseball diamond, and a playground.
Rockwood is located along part of the beautiful and historic Elora Gorge area carved out by glaciers a long time ago. The Eramosa River flows through the park past the ruins of an old cotton mill, which is now used as a picnic area and for weddings. Throughout the forest can be found ancient sinkholes from when the river was much wider, and at one end of the park are caves to be explored. Rockwood also has canoeing, fishing, and swimming. Everything a family could want for a weekend camping trip or longer that is not too far from home.
