The sap begins to move in the sugar maple trees as the length of each day increases. This is a perfect time to be outdoors; the air is crisp and bird songs are increasing. Join us on a walk to experience the sap flow and the making of maple syrup. Discover the wonder of food making from trees as we walk to the Sugarhouse to observe the boiling of sap and drawing off of warm maple syrup! Members of Aullwood and National Audubon Society are admitted free; nonmembers pay regular Aullwood general admission fees.
