Marathon Park's 78 acres are enclosed within a bustling metropolitan area and within minutes of many growing communities.  Hundreds of stately, towering white pines provide a dramatic natural setting for the recently constructed Amphitheater, central Wisconsin's finest, permanent outdoor venue with a seating capacity of nearly 10,000.

Marathon Park is also home to a miniature train and concessions at Marathon Junction, a Splash Pad, outdoor dog exercise area, a campground with heated shower building, a variety of small to mid sized reservable shelters, several playgrounds, tennis courts, pickleball court, basketball court and walking trails
