In the opposite direction from Boston as the Fells, the Blue Hills is another large reservation, also only about 20 minutes by car from downtown. It’s a place with a long importance in the region for the Native people of the area: “Massachusett,” which is the origin of both the name of the main local tribe and the state itself, refers to the highest point in the reservation. Now called Great Blue Hill, that high point provides another perfect vista of the Boston skyline, the Harbor, and the South Shore. At over 7,000 acres (2,833 hectares), this reservation offers plenty of variety—and challenge—for a leef-peeping day trip.
