Megafobia is a woodenroller coaster located at Oakwood Theme Park in Narberth, Pembrokeshire, Wales, UK. It was built by Custom Coasters International, Inc. who wanted a ride to showcase their company in Europe. Megafobia has a twister-style layout and is often ranked in the top-ten wooden roller coasters in the world.
Megafobia was the first large attraction to be installed at Oakwood Theme Park (then Oakwood Leisure Park) and it transformed the park's status from a small family country park to a major UK theme park.
