When the rain or snow hits Gatlinburg, there’s one place to head: Wild Bear Falls Water Park. A heated indoor attraction—though the roof is retractable for warm, sunny days—this splashy locale is fun for the whole family, with mountain-themed thrills, spills, and falls taking over 60,000 square feet (5,600 square meters). Think waterslides, a lazy river, hot tubs, and more.
