Dollywood's Splash Country water park will add its tallest attraction next year.

The Tailspin Racer will feature a five-story waterslide longer than a football field, allowing up to six guests to race each other on mats through spiraling tubes.

The race begins with riders descending a first drop inside intertwined, high-speed AquaTubes. Then they navigate the curves, finally emerging on a traditional mat racer-style slide. From there, it’s an all-out race toward the finish.

"From where we are now, which is finishing up the design phase, to the completion, it's about 2.2 million dollar investment," said communications director Pete Owens.

The slide will be built alongside Big River Pavilion near the park entrance.

The project comes as part of the $300 million expansion the company announced back in 2013.

Splash Country's general manager said the new slide will add an additional 12-15 new hires, plus the temporary jobs needed to take up construction.

Construction on the new ride will begin after the water park closes on September 5. It is set to open by May 2017.

It's been a great year for the water park, prompting officials to add five extra days, Aug. 15-19, to the park’s operating calendar.

It is now open daily through Aug. 21 and on weekends through Labor Day.
