2 weekends ago we took the kids through the Rideau River locks and made it to Ottawa on the boat. Sadly, we didn't have enough time to make it to downtown Ottawa or we would have missed the last locks back up the river to our marina. It's was pretty awesome and the kids loved it. Don't think we will be able to do it again this season as my sons hockey season is about to start.
We started in Manotick and went through 7 locks at 4 different lock stations, we cruised around Dows Lake and just past TD Place (old Lansdowne stadium) before leaving. Even saw a pontoon boat that looks like a pirate ship that you can have private parties on. Slightly more then 2 hours one way through the locks.
