2. Niagara Falls – New York & Canada
Niagara Falls is both in New York and Canada simultaneously, but it is more impressive from the Canadian side (via Oyster). You can still see the three main waterfalls on the American side and even take a trip on the Lady of the Mist, just as long as you remember to wear a waterproof poncho while you’re on the ride (via Oyster). The journey proves to be a wet one, but when the sun’s at the right angle, you may even be able to see a rainbow.
