Ontario is the largest province in Canada that has been luring the tourists with many top attractions. Two of the parks Lake Superior; Lake Superior Provincial Park and Pukaskwa National Park, are stunning. In Central Ontario, Algonquin Provincial Park is worth a visit for various adventure activities.
Southern Ontario is more urban. The biggest attraction in this area (and one of the most popular in the world) is Niagara Falls. Needless to say, it is a spectacular destination and a boat ride in the mist is a must!
