Andover
The solstice stones atop Holt Hill at the Ward Reservation mark the highest point in Essex County and the northern terminus of the MLT. From here it follows the Bay Circuit Trail south through the Ward Reservation and conserved lands owned by the Town of Andover and Andover Village Improvement Society to Harold Parker State Forest, diverging near Berry Pond.
The trail then enters North Andover briefly before returning to Andover on its way south to Bradford Pond in North Reading.
Harold Parker State Forest is one of the great green spaces in Massachusetts, and it sits partly in Andover.
