MOVIE PARK - Germany
2018 - Excalibur - Secrets of the Dark Forest - (5/9/18) A review and new photos of Excalibur - Secrets of the Dark Forest, a remodeled river rapids ride at Movie Park Germany, can be found at ThemeParks-EU this week.
(4/25/18) Movie Park Germany will open their new "Excalibur - Secrets of the Dark Forest" river rapids ride (formerly known as Mystery River) on May 7th, 2018. This revised version will tell the story of King Arthur and his Knights of the Round Table, as well as feature encounters with dark and fairy tale creatures from the forest. Some new teaser graphics can be found over at Themeparks-EU.
(1/31/18) Interesting new attraction news for Germany's Movie Park comes to us this week from BlooLoop. They report that the park's Mystery River attraction (rapids ride), a rarely seen indoor / outdoor themed river rapids dark ride attraction, will be given a new King Arthur theme and transformed into an all new adventure called Excalibur - Secrets of the Dark Forest. I'm guessing this may be for 2018, though no official timeline is mentioned in the article.
Fun Fact... this will actually be the third theme applied to this ride, as it opened with a "NeverEnding Story" theme.
