This historic canal is a great place to visit not only during the Summer, but Winter as well. Originally used as a safe and secure route for Montreal and the British Naval base in the War of 1812, it is a hotspot for locals and tourists alike. During the warmer months, you can kayak to get a closer look at the historic site, or during the colder months it is a popular ice skating spot. Either way, Rideau Canal is a must if you are in the Ottawa area.
