The Lachine Canal National Historic Site dates back to 1825 and features a 14-kilometre (8.7-mile) bicycle and pedestrian pathway and a permanent exhibition about the area at the Lachine Lock Visitor Service Centre (500 Des Iroquois Road). From mid-May to October, a guided boat tour uncovers how the canal continues to shape the city of Montréal. Two podcast tours are also available—Wave, which allows visitors to download an MP3 program offering sound, music, and narration of the canal’s history, and Explora, six GPS-based tours presented via mini mobile devices loaned by Parks Canada. Group tours are available upon reservation.
