Barrage Daniel-Johnson
Fourteen massive buttresses and 13 gigantic arches line the 702-foot-tall, 4,311-foot-long dam on Manicouagan River. Built between 1959 and 1970, this multiple arch-and-buttress dam is the largest in the world has been a tourist attraction since shortly after construction began. Previously named Manic-5, it contains enough concrete to build a sidewalk from the North Pole to the South Pole. Stand at the foot of the dam or walk the crest. A two-hour guided tour, for ages 18 and older (photo ID required), journeys deep into the belly of operations; email for a reservation.
