Let yourself be mesmerized by Daniel-Johnson dam (Manic-5), the largest multiple-arch-and-buttress dam in the world. Bridging the magnificent Manicouagan valley, its unique design is a true monument to Québec engineering. Whether you stand at the foot of the dam, inside it or on the crest, there are plenty of thrills in store! Opening in 2016 is the Manic-5 permanent exhibit , which takes visitors back to the 1960s when the Manic-5 jobsite was in full swing. Important: Visitors must comply with certain obligations. Be sure to read the Schedule and practical information section of the Web site.
