It's fun and at 20 CAD a steal to go on this zipline!
It's not too high so even those weary of heights can be convinced to go. Before you go, the staff will explain the proper body form and how to land safely in French and English.
The only "con":
Staff behavior at the start. Upon seeing the zipline walking into Vieux Port, my friend and I already were planning on going. The two gentlemen were aggressively telling us "Go! It's only 20. Don't be scared, all ages go and etc."
While we were filling out the forms, we overheard a family behind us asking the same two staff members safety questions and about the waiver. The conversation seemed rushed.
Lastly, the video option I would skip. The staff didn't do a adequate job of explaining how to wear the band. The staff seemed pushy on selling extras (the armband, sky-jump and picture at the end of your experience).
It was a mild turn off. However, the MTL Zipline was one of the highlights of our trip.
Avoid the frills and save some extra coin.
Take pics and short videos while getting the gear ready.
It's open until the evenings. Next trip I plan on going closer to sunset for the view!
