Hades 360 is a hybrid roller coaster located at Mt. Olympus Water & Theme Park in Wisconsin Dells, Wisconsin, USA. Designed by The Gravity Group, LLC and built in-house, it opened in 2005 and has wooden track and steel supports. In 2013, the roller coaster reopened following the addition of a corkscrew and an over-banked curve. Prior to this transformation, it was called Hades.

History[edit | edit source]

Hades under construction in 2004
The turnaround in 2011, before the corkscrew was added

In January 2004, it was revealed that The Gravity Group had begun designing a new wooden roller coaster for Mt. Olympus, which would be built in-house. No details were relased at this time, only that this would be the park's largest roller coaster.[2]

The roller coaster opened on May 25, 2005. At the time, it had a 90-degree banked curve, the highest banking of a wooden roller coaster curve.[1]

In November 2012, Mt. Olympus announced that the roller coaster would be modified and named Hades 360 for 2013. A corkscrew was added as well as a 110-degree over-banked curve and a new Timberliner train. These modifications were carried out by The Gravity Group and Gravitykraft Corporation.[3] The track length was also increased by approximately 20 feet.[1][4]

It reopened on May 25, 2013.[5] It was the second modern wooden inverting roller coaster, as Outlaw Run opened two months prior. However, Outlaw Run uses Rocky Mountain Construction's "Topper Track", which has thicker steel rails than traditional wooden track. This makes Hades 360's corkscrew the first modern inversion with "traditional" wooden track, albeit with a steel support structure.

Design[edit | edit source]


At 800 feet long, the tunnel is the longest underground tunnel on a roller coaster.[3] The first drop dives into the tunnel, which passes underneath a parking lot. When the train resurfaces, it travels through the corkscrew and round the 110-degree over-banked curve. It then dives back into the tunnel to return to the station.

Trains[edit | edit source]

The interior of the former train

Single train with 12 cars. In each car, riders are arranged 2 across in a single row for a total of 24 riders per train.

The train used today was built by Gravitykraft Corporation. Prior to the transformation into Hades 360, the ride used a train from the Philadelphia Toboggan Company.
