Mount Greylock Regional School District serves the towns of Lanesborough and Williamstown in the northern Berkshires of western Massachusetts. Williamstown is home to Williams College, founded in 1793, and the town sits near the Vermont border at the foot of Mount Greylock, the highest peak in the state. Lanesborough, located to the south of Williamstown, is a small rural community with a mix of farmland, woodland, and lakeside residential areas. Both towns are known for their scenic surroundings and proximity to the Berkshire Mountains, and Williamstown's single-family assessed values are notably higher than Lanesborough's, reflecting its distinct character as a college town.
