The Halloween fun keeps getting bigger at Jellystone Park™! Step back into our Haunted House—free with your stay—or join us with a Saturday day pass for another round of frightful fun. Campground-wide trick-or-treating returns, along with our fan-favorite site decorating contest, so don’t hold back on those spooky, silly, and over-the-top displays. Come dressed to impress for the costume contest, get creative with pumpkin painting and slime potions, and dive into eerie challenges like the witch hat ring toss and mummy wrap race. Yogi Bear™, Boo Boo™, and Cindy Bear™ will be roaming the park for photos, high-fives, and plenty of Halloween cheer. It’s the perfect mix of not-too-scary thrills, sweet treats, and glowing fall nights around the campground.
