Mount Greylock State Reservation is not only home to Massachusetts tallest mountain but also to the state’s oldest wilderness park. The summit of Mount Greylock itself sits at 3,491 feet and awards views of 5 states on a clear day. Known as one of the best hiking locations in Massachusetts its 50-miles of trails offer amazing views of old growth forests, waterfalls, overlooks. It is during the Fall season that the park really shines; when its trees turn a vivid array of colors and its rolling mountain sides become a scene made for poets.
