How far is Niagara Falls from Buffalo?

About 20 miles, give or take. If you're driving from downtown Buffalo to the falls, it's a straight shot down the I-190 N, and you'll be there in 25-30 minutes with no traffic. If you're flying into Buffalo Niagara International Airport (BUF), it's about 30 minutes to the falls, maybe 35 if you hit the Grand Island Bridge traffic on a summer weekend.

There's no direct train or subway, but you can take the NFTA bus route 40 from downtown Buffalo for $2, which takes about an hour. Uber or Lyft will run you $40-60 each way. Honestly, just rent a car or drive your own—parking at the state park lot is $10-20 for the day, and it's way easier than dealing with bus schedules.
