Mystic Timbers, Kings Island's highly anticipated new attraction for 2017, completed a test run on March 20. With 3,265 feet of track this promises to be a good ride. But we still don't know what's in the shed! We'll have to wait until April 13 - when there's a preview for participants in the Mystic Timbers First Riders auction - to find out. Mystic Timbers opens to the general public on April 15. This short video clip courtesy of Kings Island.
