While the falls are impressive from any angle, there’s nothing like looking up at them from the deck of the Hornblower, the boat that departs from the Canadian side. You will get wet from the spray, but that’s all part of the fun, and ponchos are provided. Lines for the boat ride can be long in peak season, so book ahead if possible. If you visit in winter, or anytime the boats aren’t running, check out the Journey Behind the Falls where you descend to an observation deck at the foot of the falls, 130 feet (40 meters) below.

The Clifton Hill area of Niagara Falls Ontario, known as the Street of Fun by the Falls, is a strip of amusement arcades, wax museums, haunted houses, fairground rides, and even a Ferris wheel. If you travel with kids—or feel like a kid at heart—you won't want to miss it. Or, spend the afternoon strolling through the well-tended parks along the edge of the Niagara River. There are plenty of photo opportunities and spots to stop for a coffee or ice cream depending on the weather.

The Skylon Tower offers one of the best views from Niagara Falls Ontario to the US side of the falls and beyond. There are two revolving restaurants on two levels: the Revolving Dining Room Restaurant and Summit Suite Buffet Dining Room. They complete a full revolution in an hour. Diners can go up the tower and onto the indoor and outdoor observation decks for free when eating at one of the restaurants.
