Mount Greylock is the highest natural point in Massachusetts at 3,491 feet (1,064 m). Its peak is located in the northwest corner of the state in the western part of the town of Adams (near its border with Williamstown) in Berkshire County. Although geologically part of the Taconic Mountains, Mount Greylock is commonly associated with the abutting Berkshire Hills to the east. The mountain is known for its expansive views encompassing five states and the only taiga-boreal forest in the state.
