"During warmer months, we especially swoon for the vistas at Mount Greylock. As the highest point in Massachusetts, you can see as far as 90 miles away from the mountain's peak, across four states and five mountain ranges. The park's 12,500 acres include 50 miles of trails crisscrossing the mountain, with the A.T. carving a route up the middle of Mount Greylock for 12 miles." - Travel + Leisure Editors
