Great Blue Hill

Great Blue Hill is a mountain summit in Milton, Massachusetts, and the highest point in the Blue Hills chain at about 183 meters in elevation. The peak is characterized by exposed granite surfaces that form much of its visible landscape.

The Massachusett people inhabited this land for thousands of years before European settlers arrived in the region. The arrival of colonists brought significant changes to how the land was used and understood by its inhabitants.

The meteorological observatory at the summit has gathered weather information for more than a century and remains important for understanding regional climate patterns. Visitors can observe the historic instruments and equipment that continue to serve scientists today.

Multiple hiking trails with various difficulty levels lead to the summit and are open year-round for exploration. Visit during dry weather for the easiest walking conditions on the paths.

Early English colonists named the mountain after the blue tint of the granite they noticed when viewing it from afar. This visual quality was so distinctive that it became the name for the entire surrounding area.
