Come out to Tenkiller State Park for a festive fall bash that's sure to be fun for the whole family. Enjoy a Halloween costume contest, pump-carving activities, a campsite and cabin decorating contest before the main event: a non-traditional pumpkin chunkin' competition. You'll rely on your strength alone as you hurl your pumpkin through the air in a quest for Halloween glory. Pumpkins will be supplied on a first-come, first-served basis, so be sure and arrive early. You won't want to miss this light-hearted Halloween blowout in beautiful eastern Oklahoma.
