As we made our way down south towards New York, we made a quick stop in Niagara Falls. This is only about an hour and a half from Toronto, so definitely do-able as a day trip from the city. However, Josh's sister was graduating college in Pennsylvania so we continued south the following day over into the U.S. It was definitely worth the visit, especially since we were able to find free parking within walking distance to the falls. Personally, we thought the Canadian side had a better view of the falls than the American side but that is just our slight bias. If you want to get up close and personal, there are ferries running up the center of the Niagara Falls river from both countries. Make sure you pack a poncho because everybody we saw get off the boat was soaked!
