The state park includes a campground, day-use area, and network of four-season trails for summer hiking and winter cross-country skiing. The Old Growth Forest Trail to the pine grove is a loop long. The Old Growth Forest is an even-aged stand of pines estimated to be between 350 and 375 years old. The tallest trees are between 150–160 feet tall, and have a girth of more than four feet DBH (Diameter at breast height). These eastern white pine are some of the largest trees in the eastern United States. The last remaining virgin maple and beech hardwood forest in the state is at Warren Woods State Park.
