Close out the season with the ultimate Halloween celebration at Jellystone Park™! Experience the Haunted House one last time—on us with your stay—or grab a Saturday day pass so you don’t miss the final frights of the year. Trick-or-treating throughout the campground and our spectacular site decorating contest return for one last, unforgettable showdown. Wear your best costume for the final contest of the season, create your favorite pumpkin and slime creations, and cheer on friends and family in hauntingly fun games like the witch hat ring toss and mummy wrap challenge. Yogi Bear™, Boo Boo™, and Cindy Bear™ will be joining the party for farewell photos, hugs, and a weekend full of Halloween magic. It’s the grand finale of spooky season—packed with laughter, candy, costumes, and memories that will last until next year.
