Located in the lush Smoky Mountains, Dollywood's Splash Country opened The Cascades leisure pool in 2007. WTI's giant rock grotto design makes The Cascades lagoon pool the ultimate water experience, be it leisurely or thrilling. While sun lovers are soaking up the rays in the water or in a lounge chair, thrill-seekers can weave through the rock grotto via water slide, eventually plunging back into the pool. The youngest visitors can explore the small coves at the pool's perimeter, filled with surprising interactive features. Whatever the preference of pastime, The Cascades are certain to cool families off on a hot summer day!
