Once on the island, the Martha's Vineyard Transit Authority (VTA) provides regular service to all six towns on the island, including stops at all ferry landings and the airport. The buses can accommodate a limited number of bicycles, and the island has an excellent network of well-maintained bike trails. The VTA also has free in-town shuttle-bus routes in Edgartown and Vineyard Haven. You can also get around by bicycle (rentals are available) and by taxi (an expensive option).
