How can I drive from Buffalo to Niagara Falls?
It depends where you're staying in Buffalo. If you're in the downtown area the easiest way is to take the I-190 North, crossing over Grand Island (New York) (there's a 1 dollar toll). The I-190 takes you into the heart of downtown Niagara Falls.
Mentioned in this answer:
Take the Youngman Hwy (I-290) or the Niagara Section of the Thruway (I-190). From where in Buffalo?
