Europa Theme Park, Rust, Germany

It's a rollercoaster and log flume combined

Another water-themed ride is Germany's 'Poseidon'. This unique scream machine offers the best of air and water with sharp turns, dramatic dips and a plunge into water at the end. Don't worry about getting wet The Poseidon hits the water at such speed that it merely creates a mini tidal wave as 40-foot flumes of water spray up on either side of the car.
