Take the train to Niagara Falls NY! Amtrak offers connecting service from all over the northeastern US to Niagara Falls. From NY City the trip is great! Zipping along the Hudson River all the way north to Albany. From Albany you change trains once all the way to the Falls. That portion of the trip is very scenic as it traces the majority of the route of the NY State Erie Barge Canal. The new train station opened in Niagara Falls NY in January of 2017. It is now much closer to the Falls and more convenient for transportation to the park and tourism area.
