A general trip without an exact location for either end. Going from Hempstead Long Island to Boston is about 220 miles. It would take you around 3 hours and 40 minutes. Going from the same general location in Boston to Troy New York is another 172 miles and it would take you 2 hours and 35 minutes for this.
Long Island is over 100 miles long. If you are towards the end of long island, it s faster and nicer to take the ferry from Orient Point (the north point on LI) to New London, CT. The ferry ride takes 1 hr 20 mins, but it s a relaxing trip. Then it s about a 2 hour drive to Boston.From Troy to Boston takes 3 hours.
