Rafting Montreal is the only permanent rafting company for the Lachine Rapids in Montreal. They only do the Lachines and offer rafting and jetboating. Like all outfitters, they assign a guide for each boat and send a group of rafters on their way. The boats are large and fit around 12 guests while the guide uses large oars to direct the boat. The trip consists of four major rapids and if there is enough flow, a fifth rapid. The rapids are class III and IV. I went rafting ($43) as opposed to jet boating so the trip lasted a little over 2 hours. The facilities aren't bad, there's a plumbed bathroom that you can use to change and you can rent wetsuits if desired. The rapids themselves were fun and largely large surfing holes. The large boats really cut down the turbulence and danger of the rapids. The biggest problem is that the trip is really short. The bus ride, safety talk, practice paddle, and orientation take up the bulk of your trip time so the actual time in whitewater is pretty minimal. Going through five rapids left me really wanting more. The swimmer's rapid at the end was a lot of fun too. There's large sections of flatwater as well so the constant paddling was pretty tiring. The guides didn't give a great amount of detail in how to paddle so all of the boats seemed uncoordinated. But still, it is incredibly convenient to have some a nice section of whitewater so close to the city. It took me about 20 minutes to get to from downtown. I'm incredibly envious of paddlers and surfers in Montreal.
