They just have one hybrid water coaster.

As everyone above stated, it is a water park and it has 1 roller coaster looking ride but it's kind of like the log rides. The purpose is to splash and stuff.
The rapid river felt like a rollercoaster lol
The hybrid water rollercoaster is fantastic!
Just water related, though there is a hybrid water rollercoaster
