Get ready for a spook-tacular October with four weekends of Halloween fun at Jellystone Park™! Brave our Haunted House—included with your stay—or purchase a Saturday day pass to experience the frightful fun. Each weekend features campground-wide trick-or-treating, where families can collect goodies from decorated sites, and a site decorating contest with prizes for the most creative spooky displays. Join in costume contests for all ages, get crafty with pumpkin painting and make-your-own slime potions, and play in ghoulish games like the witch hat ring toss. Yogi Bear™, Boo Boo™, and Cindy Bear™ will be out and about to snap photos, join in the festivities, and spread Halloween cheer. It’s a Halloween celebration full of thrills, chills, and unforgettable memories—perfect for the whole family!
