Over 80 Maine sugarhouses and producers are opening their doors this weekend for Maine Maple Sunday, traditionally held on the fourth Sunday in March.

Among the sugarhouses showcasing their operations and selling products are four in Waldo County, and all are open both Saturday and Sunday. Masks and social distancing will be the order of the day.

During this annual celebration of Maine's maple industry (ranked second or third behind Vermont and alternating second place with New York), producers typically offer free samples, as well as demonstrations of how pure Maine maple syrup is made. Many farms also offer games, activities, treats, sugarbush tours, music and more. And, of course, their products are available for purchase.

Here's what's happening locally.
