Dukes County, Massachusetts

Dukes County lies off the southern coast of Massachusetts as a cluster of islands. Martha’s Vineyard is the star of the show here. The island has long been a favorite summer getaway for the rich and famous.
But there’s more to Dukes County than just celebrity spotting. Pristine beaches stretch for miles along the coast. Fishing villages are all across the landscape. Their weathered shingles tell stories of generations past.
The Aquinnah Cliffs are a must-see natural wonder. Bike paths crisscross the islands and are a perfect way to explore. Dukes County isn’t just for tourists though. Year-round residents take pride in their communities.
