Wallingford-back mine was the largest mine in North America until a more profitable mine site was found elsewhere in Ontario. The mine is made up of Feldspath, Mica and mostly Quartz. This mine is one of the most popular mines explored in the surrounding capital regions. In winter the mine is accessible by snow-shoe, cross country ski and hiking trails as the roads can be extremely dangerous. Visitors come to this stunning site during the winter to skate on the frozen interior of the mine, a miraculously impressive image. In the summer months visitors come to the mine to hike, swim, rock climb, scuba dive and even zip line with their own equipment. No tools are required to explore this mine; however, a small boat may be needed to explore some of the lower parts unless you are willing to swim! The water is a beautiful blue and practically crystal clear.
