Where you start matters. If you're planning a visit, your experience - travel time, cost, border crossing - can differ a lot depending on where you begin. Here's how the main cities compare:
From New York City: It’s a 6-7 hour drive or 9.5 hours by Amtrak. A long haul, but doable as a weekend trip - especially with overnight Niagara Falls packages from NYC. Choose this if you want to include a scenic train ride and make it a bigger trip.
From Toronto: This is the most convenient jumping-off point for visiting the Canadian side. Niagara Falls is just a 1.5-hour drive (about 80 miles / 130 km), and there are frequent day tours from Toronto with hotel pickup, boat tickets, and wine tasting stops included. If you're flying internationally into Canada, pick Toronto Pearson Airport and head straight down.
From Buffalo: Just 40 minutes away, Buffalo is the best US gateway. Buffalo Niagara International Airport is served by many domestic US flights, and shuttle buses or rental cars can get you to either side of the falls quickly. If you're short on time, this is your fastest bet.
From Philadelphia, Washington D.C., or Boston: These East Coast cities also work for longer weekend trips. Driving from Philly or Boston takes around 7-8 hours; from D.C., it's about 8.5-9. If flying, connect via Buffalo. These routes are better suited for 2-night getaways rather than quick day trips.
*Local transit tips: From Buffalo and Toronto, you can also reach Niagara Falls by bus (GO Transit, Megabus, Greyhound) or train (VIA Rail from Canada, Amtrak from the US). But for flexibility, especially if you want to explore beyond the falls, renting a car or joining a small-group tour is ideal.
Bottom line: Toronto is best for day trips. Buffalo is best for quick US-side access. NYC is manageable for 2-3 day plans. Choose based on time, passport status, and whether you want to explore the Canadian or American side more deeply.
