Craziest coaster I've ridden was The Voyage at Holiday World, those 90 degree turns are sick.
The Voyage is a hybrid wooden
roller coaster, which opened in May 2006 at
Holiday World, an amusement park located in
Santa Claus, Indiana,
USA. A wooden hybrid consists of a
steel structure with
wood track. The Voyage has a lift hill of 163 feet, followed by drops of 154 feet, 107 feet and 100 feet. It travels underground through tunnels eight times. It is the third longest wooden coaster in the world at 6,442 feet and fourth fastest at 67.4 mph. In addition,
The Voyage has the most air time of any wooden roller coaster in the world with 24.2 seconds and features three 90-degree banked turns. The Voyage is also the sixth tallest wooden roller coaster. In 2006, The Voyage won the Best New Ride Award at the
Golden Ticket Awards. In 2007, The Voyage was awarded the title of Best Wooden Coaster at the same ceremony.
