The NFTA bus route
40 picks up in a few places around the city and drops you right at the falls about an hour later. We got on a stop just a few blocks past the Buffalo Yacht club by the National Guard Armory. It was a great way to go and much cheaper than renting
a car, paying for parking, gas, etc. $1.75 each...pretty good! The view is way better on the Canadian side, but the boat
tours from the American side have shorter lines, fewer crowds, and is even a bit cheaper. Walking X the bridge is easy and yes, you need passports, but it's worth it! I highly suggest it for other cruisers passing through buffalo.
