I heard via The Milky Way adventure park in Devon that today is National Roller Coaster Day. Over the years we've played a few minigolf courses next to, or underneath, roller coasters!
The Crazy Golf course at Fantasy Island in Ingoldmells sits right underneath a giant roller coaster
One of the first unplayable courses we visited on our tour was the Extraordinary Golf course at Alton Towers. Unfortunately it was flooded when we arrived on a rainy day in June 2007 so we were unable to play any of the roller coaster and ride-themed holes.
In 2011 Clacton Pier was home to a minigolf course that sat just along from the thrill rides the pier offers.
