I live in Reston VA. For reference it is near Washington Dulles Airport. I will be travelling to Niagara falls June last week. I wanted to know which mode/route will be the best for me? I wont be driving. So please let me know the same if you have any details.
Amtrak can take you from D.C. to New York, and then New York to Niagara Falls (NY) for $110 one-way. Trip from Washington to New York is 3 1/2 hours. NYC to the falls is about 9 hours.
Looked at Greyhound, the bus company, and they would run you up to NYC and out of NYC to Nigara Falls (potentially transfering in Buffalo). Looks like it's about $55 for a 7 day advance fare purchase.
Another interesting option would be to get a flight to Toronto, and then take VIA Rail to Niagara Falls. In the summer, there are quite a lot of departures towards Niagara Falls and it's a short ride. I also know that you can get some amazing summer savings on rail travel.
