Joyce Kilmer Memorial Forest is one of the Nation’s most impressive remnants of old-growth forest. The forest contains magnificent examples of more than 100 tree species, many over 400-years-old, and some more than 20 feet in circumference and 100 feet tall. This 3,800-acre forest was set aside in 1936 as a memorial to the author of the poem “Trees,” Joyce Kilmer, who was killed in action in France during World War I. This forest, part of the Joyce Kilmer-Slick Rock Wilderness, is maintained in its primitive state. The only way to see this forest is on foot. Registration for this event is required.
