Very relaxed and cool way to see Toronto and some of the small islands within in the city. I actually had no clue these islands existed and that you can even walk and bike ride around them. None the less, this is one of the reasons why the tour was awesome. Side note: It's also extremely in expensive. I was able to get some excellent photos of downtown Toronto with the CN Tower in the middle.
The tour operators were awesome. So friendly and gave us a run through of every aspect of the city's history, including the CN Tower, the skydome and other small facts that would be unknown to any tourist. They also made sure to stop the boat at different points so we could take photos and ask questions. The staff was honestly a big part of why the tour was so enjoyable.
For such a small amount of money, you get an hour tour and can even stay on of the islands and get picked up by a later return ferry. It's a great way to see the city and explore the outer islands.
