Mystic Timbers is a wooden roller coaster located at Kings Island in Mason, Ohio. Constructed by Great Coasters International and designed by Skyline Design, the roller coaster opened in the Rivertown section of the park on April 15, 2017. The ride's fictional theme is set to the site of an abandoned logging company where unexplained events are taking place. During its marketing campaign, the finale element in an enclosed shed was not revealed to the public until opening day.
Mystic Timbers was voted "Best New Ride" of 2017 in the annual Golden Ticket Awards publication by Amusement Today. Its opening also allowed Kings Island to reclaim the title of having the most wooden roller coaster track of any amusement park in the world with 18,804 feet (5,731 m).
