Tiroler Wildwasserbahn, Log flume ride in Europa-Park, Rust, Germany

The Tiroler Wildwasserbahn is a log flume ride in the Austrian area of Europa-Park in Rust. Built by Mack Rides, it opened in 1978. The 450-metre course has two drops: boats climb a lift, descend a first drop, wind through the Zauberschlucht der Diamanten rock gorge, then climb to the highest point and plunge down the second drop.

The ride opened in 1978 as the park's first attraction with a drop, built with Arrow Dynamics troughs and Mack Rides boats. In 1984 the Alpenexpress Enzian was added and a hall was built over part of both rides; it later became the "Zauberwelt der Diamanten" mine walk-through in 1998. A fire on 19 June 2023 destroyed that hall, and the ride reopened on 23 March 2024 with an open rock landscape, the "Zauberschlucht der Diamanten", replacing it.

The ride's name and setting refer to the Austrian Tyrol, and the boats are shaped like hollowed tree trunks. Since 2024 the former diamond mine hall has been replaced by the open, walkable Zauberschlucht der Diamanten, a rock landscape that riders pass through and visitors can also explore on foot.

Riders must be at least 100 centimeters (3 feet 3 inches) tall, and children under 8 years need adult supervision. The journey lasts about 4 minutes with water effects, so dress accordingly if you want to stay dry.

The Panoramabahn, the park's own transport railway, passes beneath the first drop of the Tiroler Wildwasserbahn. The ride's boats were replaced in 2005 by Mack Rides, while the flumes were built with Arrow Dynamics. A structurally identical installation, Colorado Boat, opened in 1984 at Gardaland in Italy.
