Hades 360 is a hybrid roller coaster at Mt. Olympus Water & Theme Park in Wisconsin Dells, Wisconsin. When it opened in 2005, the coaster was known as Hades; it was renamed in 2013 when the 360 degree roll was installed. It is the largest roller coaster in the park. Hades 360 is a rarity among wooden roller coasters due to its 360 degree roll, 110-degree over banked turn, and steep 65-degree drop as well as its 90-degree banked turn, as drops and angles this steep are generally not included on wooden roller coasters due to structural limitations. The ride was designed by The Gravity Group.
