Just about every hotel in the Gatlinburg/Pigeon Forge/Sevierville area in the Smoky Mountains has a pool of some sort, often a 24-hour indoor pool with a hot tub, an outdoor pool with a slide, or both. Many properties even have fun aquatic extras, like splash pads, lazy rivers, and waterfalls. But these five properties take their pool game to the next level, offering elaborate water complexes packed (or should we say drenched?) with geyser-jetted zero-entry pools, interactive playgrounds with 300-gallon buckets, and waterslides so extreme, they merit names like The Wall, Wild Vortex, and Cyclone Race.
