Located in the Berkshires of western Massachusetts, Williams offers a rich academic environment in a beautiful setting. The Berkshires—known as a cultural corridor—are a great place to live, work, and play. With natural beauty, rich history, and top-notch schools, there Berkshires hosts an array of recreational opportunities from world-class museums to hiking trails. The New York Capital Region, Albany International Airport, and Albany-Rensselaer Amtrak Train Station are just an hour away, and Boston and New York City are within a three-hour drive. The college's vibrant 450-acre campus is home to approximately 2,000 students who bring vibrancy to picturesque Williamstown. Many people relocate here for their job at Williams but stay for the community connections that they build. We hope you’ll take some time to explore the resources here and get to know more about our community–the one here on campus as well as the broader communities of Williamstown and the Berkshires.
