Size and Geography

Martha's Vineyard covers approximately 96 square miles, making it the 58th largest island in the United States and the third-largest on the East Coast, following Long Island and Mount Desert Island. Those 96 square miles break down roughly into:

Ninety-six square miles leaves room for shorelines like this one at West Chop with nobody on them.

  • Beaches: The coastline runs from the flat sand of South Beach to the clay cliffs at Aquinnah, so the beach you get depends on which shore you pick.
  • Countryside: The interior is rolling hills, farmland, and woods, with plenty of room for hiking and exploring.
  • Six Towns: Martha's Vineyard has six towns, and they don't feel interchangeable.

  • Edgartown: Historic architecture and the island's most upscale dining and shopping.
  • Oak Bluffs: The liveliest town, home of the colorful Gingerbread Cottages and most of the nightlife.
  • Vineyard Haven: The main port of entry, with a mix of traditional and newer restaurants.
  • Chilmark: Rural and quiet, with farm-to-table dining and not much else, which is the point.
  • West Tisbury: Farm country, plus art galleries and farmers' markets.
  • Aquinnah: The clay cliffs are here, on land central to Wampanoag heritage.

What Makes Martha's Vineyard Famous?

The island's reputation comes from more than its acreage:

Planning Around the Size

Ninety-six square miles is small on a map and big on a bike. Where you stay decides how much of it you see without a car: the three down-island towns sit close together and the bus links them, while the up-island towns are farther apart and quieter. Our Oak Bluffs or Edgartown comparison and where to stay guide help with the choice, and visiting without a car shows how far the bus and a bike will take you.

For a rough budget, the trip cost calculator prices the ferry, lodging and meals by season. For a plan, the day-by-day planner spreads the island over your days so the drive to Aquinnah does not eat the afternoon, and the 3-day itinerary is a good starting shape.

Frequently Asked Questions

What are the main attractions on Martha's Vineyard?

The Aquinnah Cliffs, the gingerbread cottages in Oak Bluffs and the beaches, which our beach guide ranks one by one. Each of the six towns has its own draw.

Is Martha's Vineyard the biggest island on the East Coast?

No, but it is close. At about 96 square miles it is the third-largest island on the East Coast, after Long Island and Mount Desert Island, and the 58th largest in the United States. The coastline runs from flat sand at South Beach to the clay cliffs at Aquinnah.

How many towns are on Martha's Vineyard?

Six, and they do not feel interchangeable. Edgartown is historic and upscale, Oak Bluffs is the liveliest, Vineyard Haven is the main port, West Tisbury is farm country, Chilmark is rural and quiet, and Aquinnah has the clay cliffs on Wampanoag land. Compare them on our towns page.

How many people live on the island?

About 20,500 people live here year-round. In summer the population swells to well over 100,000, which is why the ferries, restaurants and beaches feel so different in July than in November.

Can you see Martha's Vineyard in one day?

Not all of it. Ninety-six square miles and six towns are more than a day trip covers, so pick one area and enjoy it. Most day trippers stick to a down-island town near the ferry. Our one-day itinerary lays out a realistic plan.

Do I need a car to get around such a big island?

Not necessarily. There are no traffic lights anywhere, and the VTA bus connects the towns and is fare-free through June 30, 2027. Many visitors walk on the ferry and use buses and bikes. See our guide to visiting without a car.

Among the Flowers Café (Edgartown) is beloved for breakfast but expect 20–40 minute waits in season. Arrive right at 8 AM opening. The flower-filled patio is worth it.
