The ferry is what makes Martha’s Vineyard special. It’s a clear vacation at this point! The SteamShip authority has two ports, one in Woods Hole, the other in Hyannis, which is seasonal. While you do not need to make a reservation if you are traveling without a car and can just show up. If you are traveling with a car (taking it to the island), you absolutely need to make one as soon as possible (weeks to months ahead of time!). You can always chance it with car availability, but why wait? From Woods Hole to Vineyard Haven takes about 45 minutes, and is a beautiful sail. There is a bar and snack area on board. On the island end there are van taxis or rideshares that are available, and its less than a 4-minute drive from the Vineyard Haven dock, or 8-minute drive from the Oak Bluffs Dock, to 33 Beach. Lastly, use the actual website for the steamship authority aka Ferry to make reservations, etc., and avoid third-party sites for this: https://www.steamshipauthority.com/.
