While we know Orlando is home to a ton of amazing waterparks, Tennessee has a massive waterpark spanning 60,000 square feet. The Wild WaterDome Indoor Waterpark at River Lodge is the largest indoor waterpark in the state. It is nestled in Tennessee’s Great Smoky Mountains, and while there are plenty of fun attractions in this park, one in particular will have visitors feeling far out – Kaleidoscope Kavern Lazy River.
