Joyce Kilmer Memorial Forest, consisting of 3,800 acres, is known as one of the most impressive examples of old-growth forest in the country. It’s home to over 100 different tree species, many of which are over 400-years-old, and some more than 100 feet tall.
The forest was named as a memorial to Joyce Kilmer, the author of the poem “Trees,” who was killed in action during World War I. The only way to access the forest part of the Joyce Kilmer-Slickrock Wilderness is by foot on trails that loop through the huge trees. A restroom and picnic tables are located at the trailhead.
