The first phase of a US$90m (€77.2m, £68.6m) indoor/outdoor waterpark is set to open at Gaylord Opryland Resort and Convention Center in Nashville, Tennessee, later this year.

The park will open in two stages, with the indoor half set to launch ahead of the busy Christmas period on 1 December 2018.

Designed by Blur Workshop, facilities at the 111,000sq ft (10,300sq m) indoor park will include a slide tower with slides ranging up to 46ft (14m) tall, a river ride, a looping raft ride, FlowRider surfing attraction, children's activity pools, an adult infinity pool and a pool-side bar.

A 106,000sq ft (9,850sq m) outdoor park will open in Q3 2018, and will feature a 315,000 gallon wave pool with a giant LED movie screen, a 45.5ft (14m) slide tower, an adults-only pool and a kids pool with a multi-level play structure.

The resort is owned by Ryman Hospitality, a REIT specialising in group-oriented, destination hotel assets in urban and resort markets.

"There is really truly nothing like this in the US," said Ryman Hospitality CEO Colin Reed, speaking to local media. "It's an unparalleled waterpark experience."
